Thyristor power switches are used for contact-free switching of a.c. loads. A typical applicationis the switching of resistive-inductive loads at high switching rates, especially in theindustrial sector, such as in the plastics packing industry, in HVAC engineering and in theconstruction of industrial furnaces.Control and power section are electrically isolated by optocouplers.The control signal range is compatible with the logic outputs of JUMO controllers.The power section operates as a zero-voltage switch, which means that it always switcheswhen the voltage passes through zero, irrespective of the instant of the signal change.This reduces the generation of interference in the electrical supply.The input status is indicated by an LED.
