The Isolated series provides 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 input 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, pos. or neg. 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
