Sola UPS 520 1050RM
The Sola 520 1050 rack-mount UPS is rated at 1050VA. This rating is just outside the range we had specified. We still tested the 520 and included it in the main review. We didn't think the extra 50VA would make much difference. The 520 managed 43:23 (min:sec) in our run-down test. We received three rack-mountable UPSs in total. The 520 did not perform as well as the Powerware 5119 rack mount but it's almost $500 cheaper, and the 520 also cost one dollar less to run per minute. The Sola 520 was the second cheapest UPS to run based on our dollar per minute calculation. (The Powerware 5115 1000i was the only UPS that cost less to run.)
The Sola 520 looks a lot bigger than the Powerware rack-mount UPS only because it sits a lot higher. The Sola 520 weighs in at 27kg (heavier than the Powerware rack-mount UPS). The 520 is designed to protect corporate servers, Unix servers/workstations, hubs, routers, and small business servers. An increased number of servers, hubs, and routers are being placed in rack enclosures and because of this, we have started to see more rack mounted UPSs.
The Sola 520 uses the same software as the other two Sola UPSs. The 520 rack mount integrates features such as user-programmable buck/boost and nominal voltage regulation, and has a built in BestDock communications slot for expanded communication options, including PC interface via the Internet using the BestLink SNMP/ Web adaptor. The Sola 520 has the same number of LEDs on the front panel as the Sola 325, and it features the same audible alarms. We did, however, notice that some of the audible alarms beep at different second intervals. On the back are four Australian type output plugs. There are also two surge protection jacks that will protect equipment that use an RJ-11 or RJ45 connection.
The 520 user guide was very similar to that provided with the 325. It was thin but adequate and easy to follow. It features a quick startup page that steps through the installation procedure and a troubleshooting section that should get you out of any difficulties. The Sola 520 is a good all round performer. It is well priced and it performed well in the run-down test. The Sola 520 offers more bang for your buck than all of the higher scoring UPSs.
