    Features

    • Phase control: continuous intersection control, stable output, ammeter does not flutter, but half wave every cycle will generate harmonics.
    • Use load: constant impedance load, variable impedance load, IR lamp.
    • Zero-position control: Distributed zero-position control, minimum resolution is 1Hz, will not generate harmonics, and the ammeter appears jittering when output.
    • Applicable load: constant impedance load.

    Precautions

    1. Main circuit is 3-phase 4-wire input, no phase sequence is required.
    2. 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, causing e SCR burn out.
    3. SCR has a built-in fast fuse for over current and short circuit protection. If the fuse is blown, be sure to replace it with fuse of the same specification. Be careful not to increase amperage of the fuse at will.
    4. When using 3-phase load Y type connection, the center point of Y must be connected to zero line. If the center line of Y is not connected to zero line, the 3-phase load needs to be relatively balanced.
    5. When using the module, if load power is high or heat dissipation conditions are not good, please consider air cooling.

    I want to know about your 3 phase 3 wire scr power regulator
    Wondering about the 3 phase 3 wire scr power regulator.
    It says for power and voltage regulation.
    Does that mean it's good for holding amperage steady?

    The power regulator is used to adjust the power and voltage of the heating thermostat equipment and the power system and control the temperature.
    But the current stability is related to the input voltage.
