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

Specifications:

• Nominal Input/VAC: 115/230    
• Maximum Input Current @115: 5.5
• Maximum Input Current @230: 2.5
