Product InformationStore Part Number: PM3-75-12


Using only the best in manufacturing technology, Power Max has designed and built a powerhouse charger/converter. Capable of providing a constant load demand of up to 100% of its rated capacity, the PM3 series converters are among the best. Pumps, fans, motors, and radio equipment will run with no problems on the PM3 converter/charger. 

Each PM3 charger/converter has a fully integrated 3-stage microprocessor controller charger along with its highly controlled power supply output.  The PM3 can accept a low voltage input of 105 volts, and up to 135 VAC on the high end. Weighing in at only 9 pounds the PM3-75-12 is a great option for RV, radio, backup power, and pump use, as well as many other high-amperage demands. See the PM3-100-12 for the highest amperage PM3 converter/charger availible. Because of its high demand abilities, the PM3 must be installed in a well ventilated area where it will be safe from the environment.

Great converter
The unit runs quiet, and provides consistent output. It’s slightly smaller than the space used by my factory converter so the air flow is great. I would definitely recommend. Easy to install and rinds great.
