Newmar DC-DC Converters - Isolated Series

Newmar's Isolated series DC-DC converters provide voltage conversion as well as input/output isolation, allowing use of negative ground gear to positive or floating ground battery systems, or vice-versa. Many models may also be used as 12 or 24 volt stabilizers for highly voltage-sensitive equipment.

Using an Isolated Converter as a voltage stabilizer on 12 or 24 volt systems can solve conducted noise and interference problems on sensitive DC powered devices communication, navigation systems, and DC micro-processor based devices.

Features

  • Wide range of input voltage
  • Precise output voltage regulation
  • Reverse polarity
  • Input fuse/Output fuse
  • Total input/output isolation, positive or negative ground
  • Current limiting, short circuit proof output
  • Automatic re-setting thermal shutdown
  • High/low input voltage shutdown
  • Polyurethane conformal coating on PC board
  • Power ON light
  • Rugged case designed for high vibration applications

NOTE: Usually ships in 3-5 business days.
