Additional Firing boards can be configured to trigger paralleled SCR’s for very high current applications or to provide a twelve pulse driver for smooth DC control

Optional Extras

Din rail housing (W30105)

Commander module (A402131)

Signal conditioning board (A402086)

Thyristor modules,fuses & complete assemblies.


 Thyristors require a high initial gate current pulse and comparatively wide sustaining pulses to ensure reliable firing, particularly at small phase control angles. The FC36MV provides the following firing specifications

 Gate Drive: Picket Fence with a PRF of 25Khz

an initial firing pulse of; 10 volts open circuit. 750 mA into 10 Ohm, and sustaining pulses 400mA into 10 Ohm per output. The sustaining pulses are 20 uS Wide.

 High output initial triggering pulses

 Gate isolation to 3500 V rms.

 Adjustable Soft start and soft start times

 Selectable hard start and hard stop

 50/60 Hz operation auto selection

 Remote Logic input for control in noisy environment 5-24 V dc

 3 analogue control inputs 0-5V, 0-10V dc and 4-20mA

 Current control input 0-5V dc

 Over-current limit trip (Latching)

 Adjustable ramp control 0-30 seconds

 Pre-selectable or automatic Phase Angle to Burst Fire control

 Switchable Phase reversal

 Selectable Inductive or Resistive load setting

 Selectable timing delay for use as a twelve pulse driver

 High immunity to mains voltage distortions

 Complete with integral supply transformer.

 Closed loop current or voltage control via optional remote programmer and signal conditioning board
