Tornatech GPD diesel fire pump controllers built around a 24 VDC battery bank take this POWLOV0002 charger board, identified as BC1-BC2 on the panel drawing. It accepts 120/220 VAC supply and delivers up to 10 A of charging current, holding the 24-volt engine batteries ready between starts.
Where the companion POWLOV0001 serves 12 VDC systems, this 24 VDC version is the one to fit when your controller's batteries are wired as a 24-volt bank — check the battery configuration and the drawing reference before ordering. Installation is a board-level swap, so the rest of the GPD controller stays in service.
Weak cranking, persistent battery alarms, or a bank that won't hold charge are the usual reasons this board gets replaced. Cybertronic Controls is veteran-owned and based in Hammond, Louisiana — call 985-351-5681 and we'll confirm compatibility before you buy.
