BAP-1950 Three Phase SCR Driver FEATURES INCLUDE • Automatic frequency tracking of input mains from 30Hz to 90Hz (no phase delay errors!) • Automatically corrects for phase rotation • On-board diagnostic LED indicators • Feedback for solid-state over temperature sensing of SCR heatsink • Hard DC gate firing, suitable for firing large area devices • The phase reference signals are filtered to reduce harmonic content above the fundamental • On-board Feedback Control – eliminates the need for an external controller • Improved logic implementation with state-of-the-art FPGA • Optional on board Isolated voltage and current feedback inputs • Industry standard size, form factor and connector interface The BAP-1950 is a versatile three-phase bridge SCR firing board with advanced features and functions. The BAP-1950 is the ideal firing circuit for large industrial power supplies, motor controllers and generator controllers. It can be used to phase control AC mains; soft-start high power systems; produce variable, unregulated DC in it's open loop configuration; and with the closed loop feedback option, produce regulated DC output with voltage control and current limiting. The BAP-1950 is insensitive to phase sequence and mains voltage distortion. It features high gate voltage isolation, soft and instant start/stop functions, phase loss inhibit and can be used at mains frequencies between 30 and 90Hz without adjustment. Its form factor and size are industry standard and does not require auxiliary boards to implement all of its functions and options.
