Introduction
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sanyodenkilogo.jpg
I would like to thank Sanyo Denki (http://www.sanyodenki.com/) for supplying the review sample.
A few months ago I reviewed an "off-line" uninterruptible power supply here (http://www.techpowerup.com/reviews/TrippLite/Smart1000LCD/). An off-line UPS is one that switches over to the battery backup after the power is lost, ideally in such a short time that there is no disruption in power for the attached components. Another type is an "on-line" UPS, which runs from the battery all the time, charging the battery as it is needed. The unit I will be showing you today is a true on-line UPS solution. To quote CSE Magazine (http://www.csemag.com/article/CA6401714.html):
These days, however, sensitive electronic loads often can't tolerate a power outage of even one cycle and should be protected by an online UPS that provides power to the load continuously and can switch to backup power without interruption. By cleaning the normal power, online UPS systems also provide power free of interruptions, voltage or frequency variations and transients.
Features:
<blockquote>
55V AC to 150V AC input voltage window
40 Hz to 120 Hz input frequency window
Load short circuit auto return technology
Available in 1kVA, 1.5kVA, 2kVA and 3kVA models
Available in rack or tower type (rack only for 1.5kVA model)
Optional LAN / SNMP interface card

The Sanyo Denki A11H UPS came in a plain brown cardboard box. Inside the UPS was wrapped in heavy plastic and surrounded by Styrofoam.
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h18sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h18.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h19sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h19.jpg)
Included with the unit are a paper manual for the unit, instructions for the battery connection and the User Setting Guide. There is also a CD included with the SANUPS Software.

The A11H has an all-black casing with metal sides and a plastic vented front panel. Behind the right side of the front panel is the battery compartment.
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h06sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h06.jpg)
On the top left corner of the front is the control panel for the UPS. There are Power, Battery Test and Clear buttons, and an array of LEDs that show system status, including Load (%), Alarm and Battery Low.
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h08sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h08.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h09sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h09.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h10sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h10.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h11sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h11.jpg)
The back of the unit is where all the connections are made. There are two Serial connections and two DIN connections for controlling the unit, as well as Power and Reset switches. There are six total outlets that are closely spaced together, so there is little room to add power adapters directly to the unit. However, a unit like this can be used on multiple workstations or servers, and each can be connected to the UPS with a Power Distribution Unit or "power strip." Active cooling is provided by the 70mm exhaust fan which was quiet when first turned on, but under load is was a lot more noticeable. This may not be an issue if used in a server room, as most online UPS systems would be. There are also three removable panels on the back, which can be used to add optional components like the LAN interface card or connect an external battery.
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h12sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h12.jpg)
The power cable for the unit is a heavy 14AWG cable that measures about six feet in length.
[page=Optional LAN Interface Card]
Optional LAN Interface Card
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h15sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h15.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h16sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h16.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h17sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h17.jpg)
With the Sanyo Denki A11H UPS I received the optional LAN interface card. Again, the unit was packaged in a plain brown cardboard box and came with a User's Guide and Installation Manual.
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h20sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h20.jpg)
The card itself is about seven inches long and has a metal bracket around it for protection. There is also a proprietary cable that connects the card to the UPS.
Installation
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h13sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h13.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h21sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h21.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h22sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/sda11h22.jpg)
To install the LAN interface card, the right panel on the rear of the UPS needs to be removed by unscrewing two screws. The interface card can then slide into place and be secured by one of those screws. Finally, the cable is connected from the UPS to the card.
[page=Software]
Software
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software10sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software10.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software11sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software11.jpg)
If the Sanyo Denki A11H UPS is connected directly to a workstation via a serial cable, the included SANUPS Software can monitor the UPS and provide system status and power down the workstation as needed. The manual shows a serial cable should be included with the A11H. However, I did not receive one. Since I did not have a serial cable to connect the UPS, I received an error upon loading the software stating that there was no connection available.
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software12sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software12.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software13sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software13.jpg)
JT from Sanyo Denki made sure to send me the cable as soon as the error was noticed. When the connection is made, the battery condition can be seen, and charge percentage and available backup time are shown. When the input power is turned off, the display changes, showing that the output power is coming straight from the battery.
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software01sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software01.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software02sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software02.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software03sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software03.jpg)
When paired with the optional LAN interface card, the UPS can be configured by going to the IP address of the interface card and logging in. The A11H LAN interface card defaults to an IP address of 192.168.1.1. Unfortunately, this is a address often associated with a gateway in a SOHO network, and needed to be reconfigured to avoid conflicts. But before that can be done, any other device on the network with the IP address of 192.168.1.1 needs to be given a new address. It would have been easier to have the default setting be set to DHCP, especially if the default IP address would be outside the network range.

The above images are most of the pages available in the settings for the LAN card, with all of the settings at default. There are options to set up the UPS, Services (like HTTP, FTP, Telnet and SNMP), email and event logs, as well as get real-time information about the UPS.

</table>
Also plugged into the UPS were an HP PhotoSmart 8150 printer, a Belkin 4 port USB hub, a Creative Labs 5.1 speaker set, and a DSL modem/router. During the testing period the system was put through an array of benchmarking and gaming. During that period, the Sanyo Denki A11H never once gave an over voltage alarm, meaning the system was drawing too much power for the UPS to keep up with. The input voltage read in the software stayed between 115-120V. Output voltage stayed around 120-121V. Under most conditions, the A11H UPS showed the computer drawing only about 43-47% load. The highest I saw the load reach was 75%, but that was only briefly during certain portions of 3DMark06 testing. A nice feature of the A11H UPS was that the load percentage was shown on the front LED panel, since during the 3DMark testing the UPS software was not visible.
Run Time
With the serial cable connected from the A11H to the computer, the main power cable for the A11H was removed from the wall to simulate a power outage. The software showed that battery backup time for the system should have been about 10 minutes. However, I was pleasantly surprised to see the system still running at 12 minutes. At that point the battery charge level dropped to 30% and the SANUPS control software gave a warning that the battery was low and the system would be shutting down, which started after another 40 seconds. By the percentage left when the UPS shut down the PC, another 5 minutes may have been possible. That brings the total backup time to about 17 minutes, which is slightly longer than the 15 minutes claimed by Sanyo Denki under a 50% load. The SANUPS software allows multiple settings for the shutdown time, including when the battery is low (as tested), when the remaining backup time reaches as little as 2 minutes, or any amount of time after the power failure occurs.

<td>
The Sanyo Denki A11H On-line UPS is an excellent solution when sensitive equipment needs power protection. The wide input frequency range makes this UPS ideal for places that use backup generators, and the wide input voltage range allows the UPS to run longer without switching over completely to the battery, resulting in longer battery life. The optional LAN Interface card makes it easy to manage the A11H from a remote location, or the unit can be connected to a workstation or server with a serial connection.<br />
<br />
However, as with most UPS systems available, there weren't any cable management options available with the unit, and there was a limited amount of space available for power adapters. The problem with power adapters may not be as much of an issue, since many of these units are powerful enough to protect multiple machines, and power distribution units or power strips can be used to divide the power to any necessary accessories. The main issues I had with the A11H were that it used a serial cable for connection to a single machine, and that setting up the optional LAN Interface card could have been easier with DHCP enabled by default.
<br />
<br />
Overall the Sanyo Denki A11H UPS is a quality piece of equipment with an excellent set of features.

The A11H has an all-black casing with metal sides and a plastic vented front panel. Behind the right side of the front panel is the battery compartment.

On the top left corner of the front is the control panel for the UPS. There are Power, Battery Test and Clear buttons, and an array of LEDs that show system status, including Load (%), Alarm and Battery Low.

The back of the unit is where all the connections are made. There are two Serial connections and two DIN connections for controlling the unit, as well as Power and Reset switches. There are six total outlets that are closely spaced together, so there is little room to add power adapters directly to the unit. However, a unit like this can be used on multiple workstations or servers, and each can be connected to the UPS with a Power Distribution Unit or "power strip." Active cooling is provided by the 70mm exhaust fan which was quiet when first turned on, but under load is was a lot more noticeable. This may not be an issue if used in a server room, as most online UPS systems would be. There are also three removable panels on the back, which can be used to add optional components like the LAN interface card or connect an external battery.

The power cable for the unit is a heavy 14AWG cable that measures about six feet in length.

With the Sanyo Denki A11H UPS I received the optional LAN interface card. Again, the unit was packaged in a plain brown cardboard box and came with a User's Guide and Installation Manual.

The card itself is about seven inches long and has a metal bracket around it for protection. There is also a proprietary cable that connects the card to the UPS.
Installation

To install the LAN interface card, the right panel on the rear of the UPS needs to be removed by unscrewing two screws. The interface card can then slide into place and be secured by one of those screws. Finally, the cable is connected from the UPS to the card.

Software
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software10sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software10.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software11sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software11.jpg)
If the Sanyo Denki A11H UPS is connected directly to a workstation via a serial cable, the included SANUPS Software can monitor the UPS and provide system status and power down the workstation as needed. The manual shows a serial cable should be included with the A11H. However, I did not receive one. Since I did not have a serial cable to connect the UPS, I received an error upon loading the software stating that there was no connection available.
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software12sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software12.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software13sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software13.jpg)
JT from Sanyo Denki made sure to send me the cable as soon as the error was noticed. When the connection is made, the battery condition can be seen, and charge percentage and available backup time are shown. When the input power is turned off, the display changes, showing that the output power is coming straight from the battery.
http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software01sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software01.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software02sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software02.jpg) http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software03sm.jpg (http://www.techpowerup.com/reviews/SanyoDenki/A11H/images/software03.jpg)
When paired with the optional LAN interface card, the UPS can be configured by going to the IP address of the interface card and logging in. The A11H LAN interface card defaults to an IP address of 192.168.1.1. Unfortunately, this is a address often associated with a gateway in a SOHO network, and needed to be reconfigured to avoid conflicts. But before that can be done, any other device on the network with the IP address of 192.168.1.1 needs to be given a new address. It would have been easier to have the default setting be set to DHCP, especially if the default IP address would be outside the network range.

The above images are most of the pages available in the settings for the LAN card, with all of the settings at default. There are options to set up the UPS, Services (like HTTP, FTP, Telnet and SNMP), email and event logs, as well as get real-time information about the UPS.

Also plugged into the UPS were an HP PhotoSmart 8150 printer, a Belkin 4 port USB hub, a Creative Labs 5.1 speaker set, and a DSL modem/router. During the testing period the system was put through an array of benchmarking and gaming. During that period, the Sanyo Denki A11H never once gave an over voltage alarm, meaning the system was drawing too much power for the UPS to keep up with. The input voltage read in the software stayed between 115-120V. Output voltage stayed around 120-121V. Under most conditions, the A11H UPS showed the computer drawing only about 43-47% load. The highest I saw the load reach was 75%, but that was only briefly during certain portions of 3DMark06 testing. A nice feature of the A11H UPS was that the load percentage was shown on the front LED panel, since during the 3DMark testing the UPS software was not visible.
Run Time
With the serial cable connected from the A11H to the computer, the main power cable for the A11H was removed from the wall to simulate a power outage. The software showed that battery backup time for the system should have been about 10 minutes. However, I was pleasantly surprised to see the system still running at 12 minutes. At that point the battery charge level dropped to 30% and the SANUPS control software gave a warning that the battery was low and the system would be shutting down, which started after another 40 seconds. By the percentage left when the UPS shut down the PC, another 5 minutes may have been possible. That brings the total backup time to about 17 minutes, which is slightly longer than the 15 minutes claimed by Sanyo Denki under a 50% load. The SANUPS software allows multiple settings for the shutdown time, including when the battery is low (as tested), when the remaining backup time reaches as little as 2 minutes, or any amount of time after the power failure occurs.

The Sanyo Denki A11H On-line UPS is an excellent solution when sensitive equipment needs power protection. The wide input frequency range makes this UPS ideal for places that use backup generators, and the wide input voltage range allows the UPS to run longer without switching over completely to the battery, resulting in longer battery life. The optional LAN Interface card makes it easy to manage the A11H from a remote location, or the unit can be connected to a workstation or server with a serial connection.<br />
<br />
However, as with most UPS systems available, there weren't any cable management options available with the unit, and there was a limited amount of space available for power adapters. The problem with power adapters may not be as much of an issue, since many of these units are powerful enough to protect multiple machines, and power distribution units or power strips can be used to divide the power to any necessary accessories. The main issues I had with the A11H were that it used a serial cable for connection to a single machine, and that setting up the optional LAN Interface card could have been easier with DHCP enabled by default.
<br />
<br />
Overall the Sanyo Denki A11H UPS is a quality piece of equipment with an excellent set of features.
