This single-phase or phase-to-phase trigger module uses variable phase-angle control with adjustable signal matching, current limit input and adjustable soft-start. The pulse-train output is reliable, powerful and universally applicable to resistive or inductive loads. The ac input supply transformer (optional extra) is remote for increased reliability and wide operational voltage capability. Adjustable current limit allows feedback control and via a few external parts, this can give voltage or speed control of ac or dc loads. The module is fully enclosed for safety and eligibility in industrial environments.


This unit is applicable to most ac or dc, resistive or inductive loads.  Typically used in complete power assemblies (stacks) for controlling thyristors, triac or hybrid diodes on single-phase to neutral, or phase-to-phase supplies, within the line voltage limits (see typical power connections section).

  • Fires triacs or thyristors up to 440V (50/60Hz) supplies
  • MONO-LINK™ gate-to-gate firing
  • No phase timing or matching required
  • Zero voltage switching (RFI free).
  • Status LED giving output ratio indication.
