Newmar 115-12-20A Power Supply 115/230VAC to 12VDC @ 20 Amps

Heavy Duty Series

• Designed for powering 12 and 24 VDC communication/navigation equipment aboard commercial vessels where reliability is the primary consideration.
• Input voltage 115 or 230 VAC selected by slide switch on the front panel.
• Excellent Regulation and Ripple Spec: Output voltage maintained within 1% under all line and load conditions within rating; Ripple is less than 40 mV P-P. (12 volt) or 70 mV P-P (24-volt)
• Polyurethane conformal coated PC board and corrosion resistant heavy duty aluminum case with integral shock mounts assures survival in hostile environments
• Heat generated by semi-conductors is extracted and dissipated by large heat sink fins that maximize air contact for cool operation and long life of components.
• Supply and Load Circuit Protection: overvoltage, current limit; (set @ 105% of intermittent rating), thermal overload and input/output fusing.
• Thermally activated cooling fan on "CD" units.
