The POWLOV0001 is the 12 VDC battery charger board for Tornatech GPD diesel fire pump controllers. Rated 10 A with 120/220 VAC supply input, it carries drawing identification BC1-BC2 on the controller schematic and keeps the engine's 12-volt starting batteries charged so the diesel can crank the moment the controller calls for it.
A failing charger board commonly announces itself through battery trouble or low-voltage alarms on the GPD panel, or batteries that lose charge between weekly engine tests. Swapping in this board restores charging without replacing the controller — just verify your batteries are wired as a 12 VDC bank before ordering.
Fits Tornatech GPD diesel fire pump controllers with 12 VDC battery systems; for 24 VDC systems, use the POWLOV0002 board instead. Veteran-owned Cybertronic Controls ships from Hammond, Louisiana — call 985-351-5681 to confirm your drawing reference.
