32-12-35 DC Converter

Convert 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.)


  • Excellent Regulation: Output voltage maintained within 1% under all line and load conditions within rating
  • 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 components
  • Polyurethane conformal coating on PC boards and corrosion-resistant anodized aluminum cases with heavy-duty shock mounts assure survival in hostile environments

Numerous Converter and Load Protection Circuits:

  • Current limiting
  • Automatic thermal shutdown
  • Short circuit proof
  • Reverse polarity
  • Overvoltage protection
  • Carries CE mark


  • Input Voltage: 20-50
  • Output Voltage: 13.6
  • Output Amps (Intermittent): 35
  • Output Amps (Continuous): 30
  • Case 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. (5.5 kg)
  • Output: 13.6 VDC (internally adjustable 12.6 -14.5) or 24.5 VDC (or specify)
  • Ripple: 150 mV P-P maximum
  • Regulation: 1% Line/Load
  • Switching Frequency: 40 Khz
  • Efficiency: 85% – Typical.
  • Isolation: Output/Chassis; Input/chassis: 250 VDC

Duty Cycle Ratings*:

  • Intermittent: 20 minutes max on time, 20% duty. current limit set at approx. 105% of intermittent rating.
  • Continuous: 24 hours, 100% duty *24-12-3: 2 minute max. on time
  • Idle Current: Less than 100 mA (including power “ON” light)

  • 0-50 degrees C, Derate Linearly From 100% @ 40 degrees C To 50% @ 50 degrees C.
  • Thermal shutdown @ 70 degrees C Case Temperature
  • Model 24-12-3: Full output -25 degrees to +30 degrees C; Derate linearly from 100% @ +30 degrees C to 45% @ +50 degrees C

Mechanical Specifications:

  • Powder coated aluminum heat sink case
  • Front panel terminal block
  • Heavy duty mounting flange
  • Conformal coated PC board


  • Operation as a battery charger or parallel redundant operation* – derate to continuous duty rating (contact factory)
  • Extreme vibration mounting kit. (Information below)

Option: Extreme Vibration Mounting Kit

The 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 and 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 units that weigh 16–7 lbs.

This product may not be returned to the original point of purchase. Please contact the manufacturer directly with any issues or concerns.
