Newmar 32-12-10 DC-DC Converter 20-50VDC To 13.6 VDC @ 10A
Convert 20-50 VDC to 12 or 24 VDC output for powering communication/ navigation equipment, on negative ground systems. (see Isolated series, below for positive ground applications.) Ideal for powering voice, data and navigation transceivers in mobile and marine applications.
- Excellent Regulation: Output voltage maintained within 1% under all line and load conditions within rating.
- 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 overvoltage protection*. Except 3 Amp.
- Carries the CE mark
Same features as Standard Series, but with the additional capability of permitting connection 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.
Input range:10-56 VDC; positive, negative or floating ground.
Output: 12 or 24 VDC, 3 to 35 amps.
