Jxd-ir20a overvoltage and undervoltage adjustable phase sequence protector

1、Overview:
The function of this product integrates motor phase staggering protection, phase failure protection and upper and lower voltage protection. When the phase sequence is wrongly connected, the motor is out of phase and the power supply voltage fluctuates greatly, it can effectively protect the motor, and is easy to use (only connect the three-phase power supply and output control line). It has the characteristics of independent of the power of the motor and small volume. In addition, in order to resist interference, the function of phase failure delay action is added, which is an ideal protector for three-phase AC motor.
This product is in positive state, that is, when the circuit is normal, the internal relay is closed and the indicator light is on.
