Uninterruptible Power Supplies (UPS) for Sea Defense

Power critical equipment, even during a power loss.

This sophisticated power conversion equipment is intended for use on naval ships, creating a continuous flow of power to critical systems. In the event of a power outage, the Uninterruptible Power Supplies (UPS) for Sea Defense continues to power the ship using rechargeable storage batteries. Once power is restored, UPS automatically reverts back to input power and recharges its batteries. 

The UPS can also be used as a power conditioner to block surges, spikes and transients and maintain stable voltage to serviced equipment.

 

833 Series

Leonardo DRS' 3 KVA AC Uninterruptible Power Supply (UPS) provides conditioned backup power to command, control, and communication equipment where a clean, reliable power supply is essential. The input to the UPS is supplied from the ship’s 440V, 60Hz, 3 phase AC service power conforming to MIL-STD-1399, section 300. The UPS system provides 115 VAC, 60 Hz, 1 phase high quality output power. 

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 the main’s input power. 

Each UPS system is made up of a power unit, which houses the power electronics, plus control and communication circuits and a battery unit, which houses the storage batteries. The UPS system utilizes MIL-SPEC circular connectors for input, output and battery unit connection.
