3 Phase Thyristor Power Regulator, 300A-600A

3-phase thyristor power regulator features 300A, 400A, 500A, 600A huge current and control signals 4-20mA, 0-5V DC, and 0-10V DC . A power regulator has high precision, accurate temperature control, and over-temperature protective function. This SCR power regulator is a Three-phase three-wire SCR power regulator for regulating power, voltage, and controlling temperature in an electric power system.

Features

1. The thyristor power regulator adopts a simple structure, good quality, and longer service life.

2. The SCR power regulator has a linear phase-shift control circuit, high-precision correct temperature control, good stability performance, and superb heat dissipation.

3. The power regulator SCR is suitable only for resistive loads such as heaters, bulbs, tubes, ovens, etc.

4. Module Protection: The customer needs to use a semi-conductive fast fuse for load over-current protection.

5. 4-20mA, 0-5V, and 0-10V control signal modes are available which can be adjusted by the customer by using the available jumper/toggle switch.

Warning

1. The main circuit adopts a three-phase three-wire input without any phase sequence.

2. When a Y connection is used for a three-phase load, the center of Y should not be connected with a zero line, otherwise, the SCR power regulator will lose control.

3. SCR power regulator is a wall-mounted type, the vertical installation can make the power regulator achieve the best cooling.

4. The SCR power regulator is a product with a huge current, please keep in mind that terminals (A.B.C) shall be locked tightly, otherwise, the SCR power regulator will be burned by terminal heating.

5. Module protection: please use a semi-conductive fast fuse for overload and overcurrent.
