An online UPS isolates attached devices from the mains supply by using the battery path as the primary power source. This means there’s no switching delay during blackouts or brownouts, and power can be conditioned at all times. Such technology can be expensive, but the OL2000ERTXL2U offers a hefty 2,000VA/1,800W capacity for a shade under $2,000.
It’s a sturdy 2U unit that can be floor- or rack-mounted, and the LCD panel unscrews and twists to suit the orientation. This provides information about charge and load status, battery capacity or estimated run-time.
The UPS has eight battery- and surge-protected IEC C13 outlets plus one larger C19 socket. The four C13 outlets can be optionally designated as non-critical load (NCL), which will be turned off first in the event of a blackout to provide a longer run-time for the five critical-load sockets.
The UPS comes with PowerPanel Business Edition (PBE) software that monitors it and provides system shutdown services. An agent is loaded on the system via a direct USB or serial connection, while other Windows, Linux and VMware systems powered by the UPS have a client installed to receive network shutdown commands. From the agent interface you can configure the NCL sockets, schedule battery tests and power cycles for regular intervals, and remotely manage all agents and clients.
We tested the UPS with our standard dual-PSU Dell PowerEdge R515 server, which draws around 150W. With the plug pulled, the server ran for a respectable 1hr 15mins before the agent shut it down with five minutes of battery left.
The OL2000ERTXL2U is ideally suited to SMBs that want top-quality online power protection and good battery life.
