This single phase firing module has its own built in power device, reducing wiring and fixing connections. Ideal for heating loads up to 25A, when fitted onto a suitable heatsink. Burst firing operates on a 1second nominal time base. The zero crossing triggered output has a variable on/off ratio which is proportional to the manual control signal or dc input demand signal. The burst firing circuit provides trigger pulses coincide with the mains polarity crossover, ensuring complete sine wave cycles are passed through the resistive load. This prevents fast changes in load current and inhibits RFI.


Virtually all resistive loads including ovens, hot plates, furnaces, dryer heater bands, space heating and other temperature control applications, up to 25A when fitted on to a suitable heatsink (1.3°C/W).


  • 25A triac fitted.
  • Universal span and zero matching to voltage or mA control signals.
  • Status LED giving output level indication.
  • No external filtering required.
  • Consumes fewer than 2W.
  • Adjustable soft start function
