Newmar 115-12-20a power supply 115/230vac to 12vdc @ 20 amps

These super-rugged DC supplies are ideal for powering 12 and 24 volt communication equipment in base stations, remote sites and mobile communication applications where reliability is essential. The proven linear circuit design provides pure output and long life. These power supplies have been produced by Newmar for more than 25 years and are used in communication systems worldwide where high reliability in hostile environments is essential. Features 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) Input voltage 115 or 230 VAC selected by slide switch on the front panel. 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.
