3 Phase SCR Power Regulator, 25A, 40A

Features

1. The thyristor power regulator adopts multipurpose LED indication for working condition, has good quality, and long service life.

2. A linear phase-shift control circuit is used in the SCR power regulator, with good stability performance, heat dissipation, and high precision.

3. High voltage resistance available, adjustable for maximum and minimum output, more safe and reliable to use.

4. A 3-phase SCR power regulator features automatic protective functions through a built-in fast fuse.

5. 30A and 40A SCR power regulators are suitable for resistive loads such as heaters, ovens, bulbs, tubes, furnaces, etc.

6. Precise temperature control, high efficiency, and delta connection can be achieved.

7. The PCB control board of the power regulator adopts SMT production, with a separate control method, withstanding voltage, current resistance, maintenance, and no interference.

Automatic Adjustment

Phase Control

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

2. For the Y connection load, the center of Y should not be connected with the zero line, otherwise, the SCR power regulator will lose control.

3. The 3-phase SCR power regulator is designed with a fast fuse for overcurrent and short circuit protection. When the fuse is burned out, please replace it with the same specification fuse, do not use the one with larger fuse amperes.

4. SCR power regulator is a product with massive current, please keep in mind that terminals (R.S.T) and (U.V.W) shall be locked tightly, otherwise, SCR will be burned by terminal heating.

5. During the operation of this module, when the load power is high or there is a bad radiating condition, please consider wind cooling.
