Enerpro -FCRO 2100 Single-Phase Firing Board

A Single-Phase Firing/Regulating Board This FCRO2100 2-SCR firing/regulator board provides a low-cost, reliable solution for supplying hard firing 'picket fence' gate pulses in single phase AC controllers and AC/DC converters. Used in a wide variety of motor and generator controllers and industrial power supplies, the firing circuit is based on a phase-locked loop digital gate delay circuit that form the required equidistant 180° displaced thyristor gate pulses. 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.
