Product InformationStore Part Number: PM3-55LK

Overview

The PowerMax PM3-55LK charger/converter has a fully integrated 3-stage microprocessor controller along with its highly controlled power supply output. The LK Series features a selector between 3-Stage Smart charging or Fixed Output Mode* for faster charging needs.

The PM3 can accept a low voltage input of 105 volts, and up to 135 VAC on the high end. Weighing in at approximently 7 lbs pounds the PM3-55LK 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.

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. 

Note:

*The Fixed Output Mode does not offer smart charging and simply outputs at the fixed voltage. Users are highly recommended to use the 3-Stage charging mode for safe charging.

Excellent product
I installed in a rather restricted place, but made ducts for the intake and exhaust. The converter is well-made, quiet, and doing an excellent job.

Great Battery Charger
I bought this charger/converter to charge the LiFePO4 battery on my off grid system. I needed a fairly robust charger for my 325AH battery and I had to be able to adjust the output to the proper voltage. I only have to use it if we have no sun for 3 days and have only used it once since I received it 2 weeks ago. This charger performed well and replaced the 2.2 kW needed to refill the battery in about 3.5 hours, which is right in line with the specs of the charger.

Be advised whenever charging a LiFePO4 battery do not leave it unattended. This charger is not specifically made to charge this type of battery; if you know
the specific settings for your battery and make the adjustments this works great and costs about a quarter of what a charger that is made specifically for these types of batteries.
