Dual Mode Firing Circuit, DMFC12


The DMFC12 is a single phase or phase-to-phase trigger module with the option of Phase Angle or Burst Fire Control, or a combination of the two i.e. start up in phase angle and then continue in burst firing.

Standard Din Rail mount
Phase Angle and Burst Fire Control, or Combination of both
Soft-Start 0-30 seconds adjustable
Current limit (using external CT/Hall-effect device)
Enable input (volt-free)
0-5V/0-10V, 0-20mA/4-20mA or potentiometer input signal
24Vdc or 18-24Vac supply
Output power span and zero adjustment


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.
