The SAC range of Thyristor stacks is available for three phase 415V applications but other voltage supplies are available. They can control loads of up to 100A, with a number of signal control options. These stacks are assembled to suit the final load with options of phase angle, burst firing control or a combination of both. All SAC thyristor stacks come complete with appropriately rated High Speed semiconductor fuses and an integral heatsink.


Suitable for heaters, ovens, dryers, air curtains, hot plates, heating and ventilation. SCR solid state phase angle power handing gives smooth proportional control of all types of industrial processes,
