Features


Integrates the three phase phase-detection circuit, the phase-shift circuit, the control circuit and the trigger circuit.

Various control signals for selection

E, F, H types can be controlled by the manual control circuit, G type cannot be adjusted with the potentiometer

Notice


The speed control of the three phase AC asynchronous motor should be adjusted by the frequency converter, while the three phase voltage regulation module can only be applied to fan motors and pump motors where the requirements are not high. For the soft start of the three phase motors, the voltage/current closed-loop control system should be used.

The performance of the weak current part of the three phase thyristor phase-shift trigger module is stable and reliable, and the consistency of the six channels (or three channels) trigger is also very good.However, the three phase thyristor phase-shift trigger module adopts the strong current trigger mode, so if any thyristor in the main circuit malfunctions (the gate is damaged) and cannot be triggered, the corresponding trigger terminal on the three phase thyristor phase-shift trigger module will be easily damaged. This is the main deficiency of this module.

In the main circuit, an RC snubber circuit must be added between the anode and the cathode of the thyristor for protection. The resistance of the RC circuit is generally 15~30Ω, 3W or more, and the capacitance is 0.1~0.47μf, 400VAC or more.

The synchronous transformer is sold together with three phase thyristor phase-shift trigger module.
