Newmar DC Coverters
Cat. No. NM-C
Weight 2 lbs

Convert 20-50 VDC to 12 VDC negative ground output for powering communication/navigation
equipment, on negative ground systems. Ideal for powering voice and data transceivers in mobile applications.

• Excellent Regulation: Output voltage maintained within 1% under all line and load conditions within rating (except 3 amp models).
• 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 over voltage protection*.
* Except 3 Amp. Model.
