Nova Electric’s rugged CGLUPS-Series DC Input UPS is intended for military applications wherever pure sinewave battery-backed AC power is required directly from a DC input source. 28 VDC from Aircraft buss or Land Vehicle alternator feeds the CGLUPS and charges the batteries via diode isolation module, which blocks the batteries from feeding back onto the 28 VDC source. If the DC source is lost, the DC UPS continues powering the load using its internal batteries for approximately 4 minutes at full load, 0.8PF.

Nova’s CGLUPS-Series DC Input UPS systems are high-reliability power sources specifically designed for demanding applications in high shock, vibration, humidity, and EMI environments. These rugged, military UPS systems can be built to meet MIL-STD-810, MIL-S-901, MIL-STD-1472, MIL-STD-461, and other standards optionally. These models utilize the most durable componentry, offering maximum field-proven reliability for severe, harsh environments and high reliability applications such as:
