Product InformationStore Part Number: PM3-100-12


Using only the best in manufacturing technology, Power Max has designed and built a powerhouse charger/converter. Capable of provinding 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 11 pounds the PM3-100-12 is a great option for RV, radio, backup power, and pump use, as well as many other extremely high amperage demands. Because of its high demand abilities, the PM3 must be installed in a well-ventilated area where it will be safe from the environment.

PM3-100 100 amp power supply
Pros: Outstanding COMPACT power supply! This powers my Texas Star 350 HDV, RF Concepts 170 Watt VHF and TE systems 100 watt UHF Amplifiers Without breaking a sweat! Does get a little warm but the cooling fan brings the temp down FAST. Great Product and WILL recommend to others as well as this seller! Great price good customer service!
Cons: Freaked out a little when it initially went to 14.8 volts at start up. Didnt read where it would drop to 13.72 V.Slight panic attack that was my doing. Graham at Powermax cleared up any issues I had. Great customer service.
Other Thoughts: Would be nice if there was an option to ship via USPS. Some of us live in areas where theft of UPS from porches is a big and real issue. Another alternative would be for UPS to ship to a SECURE location such as a store or other "locker type" facility because of this issue.
