Description
 
Convert 10-56 VDC to 12 or 24 VDC isolated ground output for powering communication/ navigation equipment. This permits connection of negative ground gear to positive or floating ground battery systems, or vice-versa. Ideal for powering voice, data and navigation transceivers in mobile and marine applications.

Input range:10-56 VDC; positive, negative or floating ground,

Output: 12 or 24 VDC, 3 to 35 amps.

Features

  • Excellent Regulation: Output voltage maintained within 2% 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.
