DC-DC Converters - Standard Series
Convert 20-50 VDC to 12 or 24 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.

Extreme vibration mounting kit The Extreme Vibration Mounting Kit is available to protect NEWMAR power converters from the extreme stresses of shock and vibration when mounted on high–vibration vehicles. The kit (pictured here) replaces the standard vibration kit provided with the unit and fits into the unit's mounting flange to act as a "super shock absorber" for electronics in high-vibe applications. It is available to fit all NEWMAR units from 2 to 70 lbs. Specify KIT–L for units which weigh 2–15 lbs. and Kit–H for units which weigh 16-70 lbs. |
