CSN® Thyristor control type STTR

Our CSN® thyristor control, consisting of a combination of microprocessor controllers and PLC controllers with thyristor actuators, guarantees precise and wear-free control.

Description

Our CSN® thyristor controller impresses with its outstanding features: The use of microprocessor controllers and PLC controllers in combination with thyristor controllers ensures precise control without wear. The full oscillation cycle principle effectively eliminates mains feedback.
