PowerMax 45 AMP 12VDC Power Converter
Part Number: PM4-45
Power Converter/12 volt Power Supply/ Battery Charger
Built-in 4 Stage Smart Charge
Reliable, Safe and Clean 12 volt DC Power
Reverse Polarity, Overload and Thermal Protection
UL and CUL Approved
This unit converts 120 volt AC "Shore Power" to 12 volt DC power to operate 12 volt Appliances, lights, and other 12 volt accessories in your Boat, RV, Camper or Trailer. Also a "back up" power supply or battery charger for 12 Volt DC Solar panel installations, or anywhere you need a constant supply of 12 volt DC power up to 45 amps.
This unit DOES NOT have to be hooked to a battery to work, it will provide 12VDC directly to what you need to power.
As a Battery Charger, it is both a 45amp charger and a battery Tender, Maintainer.
This system provides an automatic charging system in four steps.
1. A fast charge to bring a good, drained battery back up to full voltage rapidly ("Boost").
- A standard charge to bring the battery up to a full
charge at a safe rate to prolong the life of the battery and provide power to run 12V lighting and appliances in the
3. A trickle charge to keep the battery fresh during times of load inactivity ("Storage").
4. A higher Boost mode is cycled through every 22 hours in a 24 hour continuous cycle to help with battery maintenance and improved charging. (“Desulfation”). The charger automatically changes modes to accommodate changes in conditions
