PR3-DIN 3-phase Burst-fire Power Controllers
Thyristor power control modules from United Automation which can provide seamless control of three phase electric heating loads from a suitable BMS or smilar controller. These burst firing controllers use zero-voltage switching technology to minimise noise problems caused by RFI and include over-temperature trips with automatic reset. Typical applications include HVAC systems, electric heating coils, heating cables, induction heaters and electric furnaces.
