Enerpro -FCRO 4100 Single-Phase Firing Board

Single-Phase Firing / Regulating Board Assemblies utilizing the 4-SCR FCRO 4100 board as a basis, make a low-cost alternative for field excitation on large motors. Typical uses for the FCRO 4100 would be for 2-quadrant bridge converters and, in combination with the PTIR-1 or PRTIFL1A board, 4-quadrant bridge converters. ENERPRO Firing Boards -- the industry standard for more than a decade -- employ proprietary digital LSI technology to deliver cost-effective and reliable high current "picket fence" gate pulses, soft-start circuitry, and voltage or current control of the delay angle. The delay angle varies with an inverse proportional relationship to the command angle (maximum command equals minimum delay). ENERPRO firing boards can be combined with optional auxiliary firing boards, regulator boards, and special purpose boards to provide a complete control package.
