The UPS -sc420 was delivered promptly. It was easy to install. The system initiated quickly and seems to do all that we hoped for.

If you need a small, *non-rack-mounted* UPS for use with Point of Sale applications or home entertainment systems, this is one of the most inexpensive models that you should consider. While it does not offer a lot of output capacity (only 260 Watts / 420VA), that may be enough for your application. 5 to 20 minutes of runtime, depending on the connected load may be enough. Check this one out!

I received my SC 420 this week, and right out of the box plumed in all the connections and it to power, pushed the power button and unite was up and running, We have had some storm surges and have seen no problems with the computers and monitors that are attached.

The product is great, but the process and purchase experience not so much. I ordered it on-line and it was delivered in reasonable time and works well, but I don't have a receipt. Didn't get one at purchase and didn't get one - or a packing list, with the product.

Neat little 420VA UPS which uses and older style serial connection. Still very much useful of you have equipment that uses serial. Newer units do have USB but not really totally necessary if you're using with older equipment. Definitely recommended if it fits your use scenario.

A little tricky to connect the battery the first time, but well worth the effort. I have my computer, monitor, and printer connected. Several times I have had brief power failures and my Smart-UPS kicked in smoothly and saved all my work. Well worth the investment in peace of mind and saved work.

The UPS is working fine and was plug and play. The serial interface was unexpected and worthless. The last 6 APC UPS I have purchased over the years always came with a USB connection. Not this one, my server does not have a serial connection.
