Communications Equipment Critical Power Solution
These power supplies are ideally suited for use with 12 VDC communications equipment. The switching technology has
high efficiency and includes special filter circuitry for use with all frequencies including HF. To meet individual power
requirements, peak currents from 10A to 30A are supported. Some models include Ampere and Voltage meters.
Protection Features
All models have built-in protection features including output current limiting, overvoltage protection, internal fuse
protection, and over temperature shutdown.
Easy installation, safety and reliability
These units integrate seamlessly with standard 12/13.8 VDC equipment. The output screw-type terminals are heavy
duty connections and easily accessible from the rear which ensures a safe and reliable installation
(*) ICS - Intermittent Communication Service. Peak current is limited to 50% max Duty Cycle, 5 minutes max ON time.
