The PSHC6M-1 type SCR trigger control board is a phase-shifting power controller. Its core component uses high-performance and reliable SCR trigger special integrated circuits produced by Siemens (SIEMENS). The output trigger pulse has high symmetry and stability and does not change with environmental temperature. It does not need to adjust the pulse symmetry and limit during use. It is widely used in the voltage and current regulation of various industries. Suitable for resistive loads, inductive loads, transformer primary sides and various rectifier devices such as power regulation systems.
The PSHC6M-1 is a three‑phase, phase‑shift type SCR trigger control board designed for industrial voltage and current regulation. It uses a high‑performance Siemens trigger IC to generate highly symmetric and stable pulses, suitable for resistive, inductive and transformer primary loads.
The document covers technical specifications, wiring diagrams for full‑bridge and half‑bridge configurations, parameter adjustment procedures, safety and environmental limits, and troubleshooting guidance to ensure reliable operation in harsh industrial environments.
