Detailed content

  • Modes: zero-cross / random fire
  • Trigger accuracy: ±1°
  • 24 VDC logic supply
    Features:​ Optical isolation to gate pulses, built-in SCR open/short detection, programmable ramp.
    Materials & Structure:​ Aluminum heat-spreader base, FR-4 control PCB, fiber/opto-isolators, screw pulse terminals.
    Working Principle:​ Sync transformer derives mains phase; controller delays gate pulse per setpoint; pulses fired through isolator to SCR gates.
    Installation:​ Mount in panel with clearances for heat sink; separate pulse wires from power bus; shield sync transformer leads.
    Precautions:​ Never fire into open SCR; verify phase sequence; disable output before probing gates.
