Description
Thyristor power switches are required for contact-free switching of alternating current consumers. A typical application is the switching of ohmic-inductive consumers at a high switching frequency, especially in the industry, as, for instance, in the plastic packaging industry, in air conditioning and heat technology as well as in industrial kiln/furnace construction. Control and power section electrically isolated by opto-couplers. The control signal area is compatible with the logic outputs of the JUMO controllers. The power section operates as a zero voltage switch, i.e. switching always takes place at zero voltage, independent of the time when the control signal changes. This avoids noise or interference voltage. The input status is displayed by an LED.
