RS232 Under Over Voltage Current Protector surge Monitor reclosing protector

 

(1) Overvoltage and undervoltage protection When the voltage is low/higher than the set value, the protector automatically disconnects the power supply; after the voltage is normal, the automatic closing is energized.

 

(2) When the overload/short circuit is short-circuited or the current is greater than the rated current, the protector is disconnected for protection.

 

(3) If the leakage protection circuit exceeds the specified leakage current, the protector will be disconnected immediately.

 

(4) Lightning protection The 1.2/50us (8/20us) combined wave is added between L-N, 2kV does not cause malfunction, and 6kV does not damage. With three levels of lightning protection.

 

(5) Zero-fire line reverse protection When the zero-fire line is reversed, it will not be closed/or automatically disconnected to avoid electrical burnout and accidents.

 

(6) Neutral disconnection protection When the “zero line” on the incoming line side is loose or cut, the three-phase voltage is unbalanced to a certain value, the protector is opened, and after the recovery, it is automatically closed.

 

(7) Automatic disconnection when power is off When the line is powered off, the input and output lines are automatically disconnected. When the re-incoming call is avoided, the electric appliance is burnt due to the abnormal power supply. When the call is re-initiated, if the power supply is normal, the power is automatically turned on.

 

(8) Fault detection before closing Before the closing, the voltage of the power supply line is automatically detected, the zero-fire line is reversed, and the neutral line is disconnected. If any fault exists, the power supply is rejected.

 

(9) Automatic reclosing After the trip occurs, it will automatically re-close after a certain time interval. The manual closing is reduced, the continuity of power consumption is ensured, the operating rate is improved, and the user is more convenient.

 

(10) The remote control has an RS232 communication interface inside, which can be externally connected when needed, and is convenient to be connected with remote monitoring equipment to realize remote monitoring.

 

(11) Fault indication When the above protection is disconnected, different red indicators are on, indicating the corresponding fault type.
