Three Phase SCR Firing Boards
Three Phase
The industry standard Enerpro FCOG6100 remains a proven solution for industrial power supplies, battery chargers, motor and generator controllers. Other boards feature additional six gate outputs and polarity transition circuits, high voltage tolerant, high output gate pulse transformers and increased creepage distances.
FCOG6100 Standard Firing Board
The FCOG6100 provides economical and reliable phase-angle control of SCR AC controllers and DC converters operated from three-phase mains. The board features six isolated gate drives, independently configurable soft start/soft stop control inputs, and an analog delay angle command input configurable for a variety of common voltage or current ranges. A variety of current and voltage regulator boards are available in addition to auxiliary firing boards for remote or parallel SCR arrangements.

FCOVF6100 Variable Frequency Firing Board
The FCOVF6100 variable frequency firing board provides the functionality of the industry-standard FCOG6100 firing board for applications with variable-frequency AC mains. An onboard frequency compensation scheme makes the firing circuit less sensitive to line frequency variations while an isolated DC-DC converter provides enhanced control power flexibility. The FCOVF6100 is offered in a standard 30-140 Hz frequency of operation range and customer-specific ranges to 600Hz.
