PowerMax Battery Chargers

The PowerMax PM3 units are 3 stage units using a built in microprocessor controller to regulate charger functions, which provides efficient charging to the battery charger's maximum output (constant current), and monitoring of output voltage as it rises to the charger's absorption set point. The battery charger then maintains this absorption voltage (constant voltage) until the battery is fully charged. The charger then drops the output voltage to the 3rd mode, or "float" stage, which is safe for long term battery maintenance.

The PM3 series is protected by multiple protection features for a long, trouble-free life. 1) Reverse Battery Polarity Protection. 2) Brown-Out Input Protection. 3) Over-Current Protection - cycle by cycle peak limiting as well as rated current limiting to maximize the life of the charger. 4) Over-Temperature Protection. In addition, it is designed with a “proportional” fan control circuit. Fan speed is directly proportional to the converter’s internal ambient temperature. This enables the fan to turn on and off very slowly, minimizing unwanted fan-starting noise.

PowerMax PMBC Power Supplies

For automotive use, provides constant clean power supply during diagnostics and reprogramming and battery charging through a fully regulated DC output. Multiple protection features including: Overtemp, Brownoutinput, reverse polarity, over-current. Standard features include: 2 year warranty, 15 Foot clamp set, on/off switch, voltage adjustment knob (12.5 to 16.5 VDC), and digital voltage display. These are the latest "LK" models
