The main interface board for Trojan UVSwift SCA and UVLogic AM systems, original part number 912492, operating at 240 V. This is the control printed circuit board that sits between the system controller and the reactor hardware: it carries the lamp, sensor and interlock signalling that lets the controller report lamp status, UV intensity, power level and alarm state, and it is what a plant SCADA link ultimately reads from. It is a control board, not a lamp ballast, despite being grouped with the ballasts. The UVLogic AM and UVSwift SCA reactors share a common parts family — they take the same quartz sleeve — which is why one board is listed against both. Supplied by cBallast on quote-to-invoice terms; lead time and freight are quoted per RFQ against the destination Incoterm.
