Burst Firing Trigger Module, FC11BL


Single phase burst firing modules for driving triacs and thyristors with resistive loads.

Fires triacs & thyristors up to 440V
RFI free, zero voltage switching
Selectable soft-start function
Opto-coupled output
MONO-LINK® gate-to-gate firing
Voltage control or 4-20mA current loop
Auxiliary 5Vdc output for manual control
LED output power indicator


The number of complete mains cycles during fixed repeating periods (typically 1 to 10 seconds) is varied, thus altering the duty cycle or on-/off-time ratio. Trigger pulses coincide with the zero-crossing times of the mains supply thus ensuring no RFI is produced when using resistive loads.
