32-12-35 DC ConverterConvert 20-50 VDC input to 12 VDC negative ground output for powering communication and navigation equipment on negative ground systems. (See Isolated Series for positive ground applications.)Features:Excellent Regulation: Output voltage maintained within 1% under all line and load conditions within the ratingThe heat generated by semi-conductors is extracted and dissipated by large heat sink fins that maximize air contact for cool operation and the long life of componentsPolyurethane conformal coating on PC boards and corrosion-resistant anodized aluminum cases with heavy-duty shock mounts assure survival in hostile environmentsNumerous Converter & Load Protection Circuits:Current limitingAutomatic thermal shutdownShort circuit proofReverse polarityOvervoltage protectionCarries CE markSpecifications:Input Voltage: 20-50Output Voltage: 13.6Output Amps (Intermittent): 35Output Amps (Continuous): 30Case Size (H x W x D): 6.0 x 4.7 x 16.0 inches (15.2 x 11.9 x 40.6 centimeters)Weight: 12 lb.

(Information below)Option: Extreme Vibration Mounting KitThe Extreme Vibration Mounting Kit is available to protect NEWMAR power converters from the extreme stresses of shock and vibration when mounted on high-vibration vehicles. The kit replaces the standard vibration kit provided with the unit. It fits into the unit’s mounting flange to act as a ‘super shock absorber’ for electronics in high-vibration applications. It is available to fit all NEWMAR units from 2 to 70 lbs. Specify KIT L for units that weigh 2–15 lbs. and Kit H for 16–7 lbs.This product may not be returned to the original point of purchase.
