POWER SUPPLIES HEAVY DUTY SERIES

These super-rugged DC power supplies are ideal for powering 12 and 24 volt communication/ navigation equipment onboard commercial vessels where reliability is essential. The proven linear circuit design provides pure noise free output and long service life.

FEATURES

  • Excellent Regulation and Ripple Spec: Output voltage maintained within 1% under all rated line and load conditions
  • 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 for cool operation
  • Protection: overvoltage, current limit; (set @ 105% of intermittent rating), thermal overload and input/output fusing
  • Thermally activated cooling fan on “CD” units

Option: Extreme Vibration Mounting Kit

The Extreme Vibration Mounting Kit is available to protect power converters from the extreme stresses of shock and vibration when mounted on high vibration vehicles.

The kit (pictured here) 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 tor units which weigh 2-15 lbs. and Kit-H for units which weigh 16-70 lbs.
