DC-DC Converters Standard Series

Convert 20-50 VDC to 12 or 24 VDC negative ground output for powering communication/ navigation equipment, on negative ground systems. (see Isolated series for positive ground applications.) Ideal for powering voice, data and navigation transceivers in mobile and marine 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 long life of components.
  • Polyurethane conformal coating on PC boards and corrosion-resistant anodized aluminum case 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 and overvoltage protection*. * Except 3 Amp. Models.

All models now CE certified for sale/use within the European Union (EU).

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-vibe applications. It is available to fit all NEWMAR units from 2 to 70 lbs. Specify KIT-L for units which weigh 2-15 lbs. and Kit-H for units which weigh 16-70 lbs.
