The HAC range of thyristor stacks is available for single and three phase 240/415V applications (other voltages can be accommodated). They control loads up to 160A, with a number of control options. They are assembled to suit the final load, with options of phase-angle, burst-firing (3 or 2/3rds phase-control) or a combination of both burst firing and phase angle (typically, using the FC36M). All standard HAC thyristor stacks are fan cooled and fitted with at least one thermal trip for added safety of overheating.
Suitable for heaters, ovens, dryers, air temperature, hot plates, duct heating and ventilation. SCR solid state phase angle power handing gives smooth proportional control of all types of industrial processes, e.g. furnaces, electroplating, controlled rectifiers, transformers, motors.
