DC Gate 80
Paradan radio presents the DC Gate 80
This is a 13.8 volt high-power battery back-up system for powering your radio station, repeater, or other equipment. It can supply up to 80 amperes from either the power supply or the battery. Whenever the ac power is lost, this unit instantaneously switches from the power supply to the battery. The switching element is a dual Schottky Diode. There is a built- in four-stage 10-20 amp battery charger to rapidly restore the battery following a power outage. Charge current, and battery voltage, are displayed on the LCD digital meter. One-quarter inch brass studs assure robust electrical connections.
