The DCU20 is a microprocessor controlled DC-UPS rated 20A usable in 12V or 24V systems. DCU20 monitors the voltage supplied by a DC source and in case of power failure a backup battery is connected to the load. When powered externally the unit charges the battery by an integrated battery charger supporting various battery chemistries.
