GTCM-U, GTCM-R solid-state voltage regulating trigger module external dimensions Installation wiring diagram: (unit: mm)

Notes:
Due to the low heat generated by the triggering module itself, it does not need to be installed on the heat sink.
The anode and cathode of the thyristor in the main circuit generally require the addition of a resistance capacitance absorption circuit for protection, with a resistance of 50-100 Ω/5W and a capacitance of 0.1-0.47uF/400VAC, or the use of a specialized overvoltage protection absorber produced by our factory.
When selecting thyristors and rectifiers in the main circuit, the current and voltage parameter values should be 2-4 times larger than the actual values.
The requirements for heat dissipation, cooling, and installation of thyristors and rectifiers in the main circuit can refer to relevant requirements.
