SRC Series for resistive loads

This range of thyristor stacks has been specifically designed for burst fire control or single cycle burst fire control of resistive loads in medium and high current heating applications for furnace, ovens, dryers etc. These units use a proven MOSFET driver circuit, originally developed in 1995, and feature closely controlled zero-voltage switch on, and low crossover commutation noise.

STA Series for transformer coupled loads OBSOLETE

This series is now obsolete but existing items can normally still be repaired if required. Suitable replacements may be found in the RLS2000 series which has similar control modes for transformer loads. Data sheets and manuals for the STA series are still available in our DOWNLOAD AREA
