The Pulsar EX RT online uninterruptible power supplies (UPSs) feature an extended runtime option using Ballard Power Systems' Nexa RM fuel-cell modules. The rack systems offer power protection optimized for maximum reliability and long backup times for high-density IT applications and servers. Models powered by the 3200-VA fuel cells can provide virtually unlimited backup time as long as hydrogen fuel is supplied. Contained in replaceable cylinders, hydrogen is piped directly to the fuel-cell modules. Call the company for pricing information.
