Misphase protection: The sequence of three-phase power connection error can cause open and close direction of the electric actuator to be wrong, and sometimes even damage the valve or actuator. JDX can real-time monitor the three phase of power, so when it finds misphase, it will cut off the power of motor by control circuit to protect motor and equipment.

Phase loss protection: If the voltage of any phase connecting with three-phase current motor is low, it can cause the motor to run abnormally and even to burn down. When JDX can find the voltage of any phase lost or low, it will cut off the power of motor to protect motor in time and equipment.

The JDX module is composed of a printed circuit including microprocessor and a case and the case is equipped with indicator lights for easily observing the working state of JDX.
