Enerpro - Auxiliary Firing Boards

Each ENERPRO auxiliary firing board provides the ability to drive six to twelve additional SCRs. You can also daisy-chain up to five auxiliary firing boards with a single Enerpro firing board. Auxiliary firing boards can be used with the FCRO-4100, FCOG-6100, FCOG-1200 and FCOVF-6100 models.

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.

FCOREM-60 Six-SCR Auxiliary Firing Board

The FCOREM-60 is the high voltage version of the FCOAUX-60, when in combination with the FCOHV-61 firing board, allows 4-quadrant operation at mains voltage up to 900 VAC. This firing board is used whenever the firing board and the SCR are separated by large distances.

Enerpro FCOA-1200 Twelve-SCR Auxiliary Firing Board

The FCOA-1200 board supplies delayed hard firing "picket fence" gate pulses for gating paralleled and series connected 12-pulse converters or AC controllers. This board is used in conjunction with the FCOG-6100 board, or DDOG-1200 board, utilizing the logic circuitry.
