Thyristor Control of Silicon Carbide Heaters

CD Automation thyristors can be operated in a single cycle burst mode which is optimum for silicon carbide heaters. At 50% output the thyristor is one cycle on, one cycle off, i.e. 0.02s on, 0.02s off (at 50Hz) which minimises the risk of over-stressing the silicon carbide heater during the on period.
