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.
