Newmar Isolated Series DC Converter

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 24V stabilizers for highly input voltage sensitive equipment.

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