115-12-20A Power Supply

This super-rugged DC power supply is ideal for powering 12-volt communication and navigation equipment onboard commercial vessels where reliability is essential. The proven linear circuit design provides pure noise-free output and a long service life.

Features:

Excellent Regulation and Ripple Spec (output voltage maintained within 1% under all rated line and load conditions)
Polyurethane conformal coated PC board and corrosion-resistant heavy-duty aluminum case with integral shock mounts assure survival in hostile environments
The heat generated by semi-conductors is extracted and dissipated by large heat sink fins for cool operation
Protection: overvoltage, current limit; (set @ 105% of intermittent rating), thermal overload, and input/output fusing
Thermally activated cooling fan on “CD” units
