SCR Power Controller With Temperature

SCR Power Regulator, also known as a thyristor power controller, is a device that controls the delivery of electrical power. They are designed to vary AC voltage across resistive and inductive loads. They have many advantages such as large capacity, high efficiency, good controllability, long life and small size. They are a bridge between weak current control and controlled strong current.

SCR Power Regulator is an extremely important power electronic device that can control megawatt-level power with extremely small control power. It is often used in rectification, switching, frequency conversion, inverter and other circuits. High-power SCR uses a very large area The silicon wafer needs to be packaged in a tube shell with a heat sink.

Application

Thyristor power regulator, also known as SCR power controller is used to control power delivery.widely be used:

1. Aluminium melting furnaces;

2. Holding furnaces;

3.Boilers;

4.Microwave dryers;

5.Multi-zone drying and curing overs;

6.Plastic injection moulding requiring multi-zone heating for mainfold moulds;

7. Plastic pipes and sheets extrusion;

8. Metal sheets welding systems;

Warning:

• The main circuit adopts three-phase three-wire input without requirement for phase sequence.

•  SCRis a product with bigcurrent,pleasekeep in mind that terminals(R.S.T)and (U.VW)shall not be locked tightly, or SCR burned by terminal heating. 

• When Y connection is used for three-phase load,the center of Y should be connected with zero line,if not so, relative equilib rium of the three-phase is required. ·When the temperature of radiator exceeds 75℃:,the module will stop working automatically,and only the power indicating light is bright on the moment.oling.
