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 auxilliary firing boards, regulator boards, and special purpose boards to provide a complete control package.

FRS-300
The FRS-300 offers a reliable, low-cost alternative to other methods for charging the DC bus in various applications. The FRS300 combines the convenience
of having the firing, regulator and snubber circuit all on one board.
Other applications for this board would be in 3-phase battery chargers, welding equipment and other DC bridges where power quality is not an issue.

FCOG-6100
Three-Phase Firing BoardIntroduced
in 1983, this industry-standard firing board is ideal for large industrial power supplies, motor controllers and generator controllers. Reduced component count and improved reliability is achieved by utilizing
an industry-standard digital LSI-based design. The firing circuit's phase-locked loop digital gate delay circuit forms a set of phase-balanced, 60°-spaced, high current thyristor gate pulses in response to a voltage
or milliampere control input.
