Wilmore's Series 1600 DC-to-AC inverters are designed to provide uninterrupted power to AC-powered electronic equipment in data/communications network installations powered by DC battery plants. Compatible with 19 and 23 equipment racks, these compact (3.5 high), highly-efficient (up to 90%), convection cooled inverters are designed to be reliable and cost effective alternatives to the bulkier and more expensive units available to communications network operators. Series 1600 inverters provide an isolated, regulated, frequency stable quasi-sine0wave output, with output power ratings of 500 and 1000 VA. Optional built-in automatic load switchover circuitry permits operation in uninterruptible or standby modes. Standard input voltages are 24, 48, and 130 V DC with standard outputs of 120 V AC/60 Hz and 230 V AC/50 Hz.
