Wiring Diagram of Thyristor Power Regulator


Precautions
- Main circuit is 3-phase 3-wire input, no phase sequence is required.
- Applicable load: constant impedance electric wire, IR far infrared, UV lamp, etc.
- SCR is high current product, please be sure to lock the (R.S.T) and (U.V.W) terminals, otherwise the terminals will heat up and the SCR will burn out.
- In the Y type wiring method, center point cannot be connected to zero line, otherwise the SCR will lose control.
- When temperature of the heat sink exceeds 75℃, the module will automatically protect and stop working. At this time, only the power indicator LED is on.
- SCR is wall-mounted and can be mounted vertically for best heat dissipation.
Thyristor power regulator price is competitive, can be used in electric power system for power or voltage regulating and temperature control. Rated current can select 75/90/120/150/200/250A, rated voltage is 380VAC, input is 3 phase 3-wire. Control signals are optional in 4-20mA, 0-5VDC, 0-10VDC. Power controller comes with protection function, safe and durable.
