Technical info

Applications

They are used to regulate the power delivered to the receiver, where this power is proportional to the input control signal. They are used in automation control systems where smooth control of receiver power is required for resistive loads. Typical applications for power controllers: heaters, industrial furnaces (annealing, quenching, drying, etc.), dryers, plastics processing equipment, industrial sealing machines, glass production industry, industrial heating systems (matting and lining of pipelines).
