 CTM Three PhaseAC Voltage Regulating Module

 (lt can be used as three phase fan speed controller)

     CTM isolation three-phase voltage regulating module sets three-phase potential detection,
phase shifting circuit, trigger circuit and three groups of anti parallel one-way SCR at an
organic whole, need not external synchronous transformer, through l-5VDC, 2-10VDC 4-20mA
signal, automatic control or external potentiometer manual control to achieve change
conduction Angle is implemented three-phase load voltage from o to grid whole voltage of
acljustable steplessly, widely used in industrial furnace, electric oven, lamplight illume,
transfonner primary surge in equipment such as temperature adjustment, dimrner, voltage
regulating control, also applies to fan, pump ruotor control.


Main Characteristic
    Three-phase integration design, have power, control and fault indicationj convenient installation, input and
output terminal photoelectric isolation, built-in overheating protection function and the RC surge absorbing circuit,adjust, the linear good,strong anti-jamming capability, which can be directly and temperature is used together.
