AOYI Power stabilizer Regulator scr automatic thyristor HNSCR 120LA ZQ Power Regulator pid controller

△  Novel appearance,heat dissipation optimization,high performance,high quality.

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

2. Applicable load: Constant impedance, IR far-infrared Ray, UV lamp, etc. 

3. When loading Y connection, the center point cannot be connected with zero line, otherwise, the SCR will lose control. if three-phase load is unbalanced, the center point must be connected with the zero line, our product of three-phase four-wire system can be chosen.

4. SCR is wall-mounted, and vertical installation for optimum heat dissipation.

5. SCR is a product with big current, Please be sure to lock the terminal (R.S.T) and (U.V.W) tightly, or SCR will be burned by terminal heating.

6. When the temperature of radiator over 85℃,SCR will stop working automatically, please check whether the actual load current is out of the range of SCR. The environment of SCR should be improved to make it well ventilated. Power on and operating after troubleshooting.

7. When the load is not used, disconnect the control signal to make the SCR output zero, and then cut off the power supply of the main circuit.

8. When the SCR has lain idle for three months and has not been used, please deal with the surface dusts and charge it once .Method: Connect the line according to the manual VR adjustment wiring diagram, adjust the potentiometer to make the distance between E1 and E2 is 0Ω.Sending the three phase electricity and turning the potentiometer slowly to make the SCR output less than 20V. Working 5 minutes like this.

9. Operating environment: Please use in an environment that is well ventilated, free from direct sunlight or heat radiation, non-corrosive and non-flammable.
