Critical Power Solution for 13.8Vdc Mobile Equipment
These DC-DC Converter power supplies are ideally suited for use with mobile 12/13.8 VDC equipment. Both Isolated and
Non-Isolated models are available. The design technology emphasizes high efficiency, tight regulation and low
ripple/noise. To meet individual peak power requirements, models support peak currents up to 25% above nominal.
Protection Features
All models have built-in protection features including output current limiting, overvoltage protection, internal fuse
protection, and over temperature shutdown. Isolated models include a crowbar on the output to prevent damage.
Easy installation, safety and reliability
These units integrate seamlessly with standard 12/13.8 VDC equipment. Screw-type terminal connections are used
which are easily accessible and ensure a safe and reliable installation.
(*) Intermittent Communication Service. Peak current limited to 50% max Duty Cycle, 5 minutes max ON time.
