FCOAUX-60
Six-SCR Auxiliary Firing Board

The FCOAUX-60 operates in conjunction with the FCOG-6100 board, or the FCRO-4100 board, where operation of more than six (or four) is required. Typical examples would be paralleled SCR applications and 4-Quadrant operation.

Used in Parallel SCR Gating
Used in Power Supply Reversing Applications
