Product Description
Newmar DC to DC Converter. Converts DC 32 volts down to 12 volts @ 35 amps. Unit was used in 24 volt construction equipment to lower voltage to 12 volts to operate radios and other DC equipment. Unit is 7" wide, 6" tall and 14" long. Unit has been tested and works as it should. Missing plexiglass cover over input/output connections but does not affect its functionality.
Manufacturer Features & Specs
-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 Isolated series 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. Performance Specifications - Standard & Isolated Series
