Specifications and Features

As described earlier, the thyristor unit normally holds the input signal control circuit and power element in one unit for the configuration of error detection and current control circuit. Thus, the unit can be conveniently used, and is commonly used for heater and AC control. However, thedisadvantage of the thyristor unit is the high price depending on the function available. Woonyoung Co., Ltd. specialized in the production of SSR, produces the power control unit for SSR to have the economic price using the control unit and SSR for simpleAC power controller.
