Enerpro - Firing Boards

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.

	Enerpro FRS 300 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.
	Enerpro FCRO 2100 Single-Phase Firing/Regulating 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 FCRO 4100 Single-Phase Firing/Regulating 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 FCOG 6100 Three-Phase Firing Board Introduced in 1983, the FCOG6100 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.
	Enerpro FCOG 61BP Three-Phase Bi-Polar Firing Board The FCOG61BP Bipolar Thyristor Firing Board represents the most recent addition to the Enerpro family of phase-control technologies. Based on the proven, time-tested FCOG61003-phase firing boards the FCOG61BP provides users the flexibility for polarity switching rectifiers and sequence-switching ac controllers.
	Enerpro FCOVF 6100 Variable Frequency Firing Board The FCOVF-6100 board is the variable frequency/variable voltage version of the industry standard FCOG 6100 board. This board is capable of utilizing input mains variable frequency and variable voltages coming from large alternators, converting the AC voltage to DC for field excitation and battery charging. Typical uses would be in diesel / electric vehicle
	Enerpro FCOG 1200 Twelve-Pulse Firing Board The FCOG 1200 firing board supplies delayed, hard-firing gating pulses for parallel or series connected 12-pulse converters or AC controllers. The 12-gate outputs are spaced at 30° intervals required to eliminate the 5th and 7th harmonics of the AC input current.
	Enerpro FCOP 1200 Twelve-Pulse, Two-Board Firing Package The FCOP 1200 twelve-pulse firing package is made up of the DDOG1200 Gate Delay Determinator board mounted on top of the FCOA 1200 Auxiliary firing board. This combination is able to handle mains voltages up to 900 VAC.
