Enerpro -FRS300 Firing Board

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. 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.
