Flash Sale 3-Stage Smart Charger, 15 amp 12 volt

PowerMax PM3-15LK AC to DC converter/charger for 12V DC systems, featuring 3-stage smart charging, fixed voltage power supply mode, lithium compatibility, variable voltage adjustment, LED status indication, and built-in cooling fan operation.

The PowerMax PM3-15LK is part of the PM3 Series converter/charger lineup, designed to convert 120V AC power to 12V DC power for battery charging and DC load support. The PM3 Series supports built-in 3-stage smart charging and fixed output modes, giving installers flexibility for charging batteries or directly powering 12V equipment.

In 3-stage charging mode, the unit automatically moves through boost, normal, and storage charging stages. Factory smart charging voltages are listed as 14.6V, 13.6V, and 13.2V. Fixed voltage mode allows the output to be adjusted from approximately 13V to 16.5V for applications that require a constant DC output.

The PM3 Series is lithium compatible, works with multiple battery types, and includes protection features for reverse polarity, overload, and thermal conditions. It is intended for interior installation and must be installed by a certified electrician.
