0.8 KW DC Uninterruptible Power Supply (UPS)

Leonardo DRS’ 0.8 kW DC Uninterruptible Power Supply (UPS) is intended for use on board naval combat ships to power critical command, control, communications and navigation equipment. The input to the 0.8 kW UPS is supplied from the ship’s 440V, 60Hz, 3 phase AC service power conforming to MIL-STD-1399, Section 300. 

If input power is lost, or if the power quality is outside acceptable limits, the UPS system continues to provide the output power for the specified duration using rechargeable storage batteries and upon restoration automatically revert to main’s input power.
