High quality Single Phase Voltage Current Protective Adjustable Over Under Voltage Protector Electric Power Protector

20A-2P-1NO1NC详情页

Products Description


      WDS238-VAP type multi-function Protective Device is designed to measure single phase two 

wire AC active energy and used in overvoltage protection, under voltage protection and over-

current protection . In case of over-voltage fault, under-voltage fault or over-current fault in line, 

this product can instantly power off the load to prevent electrical equipment from being burnt. 

The over-voltage, under-voltage and over-current values of this product can all be set up by 

yourself and can be adjusted on the basis of local practical condition .It is a long use-life product 

with the advantage of high stability , high over load capability , low power loss and wide working 

voltage range.


Features


1. LCD display with backlight, can display total active energy (kWh), real time current (A),

    voltage(V), active power (W).

2. LCD display kWh (4 digital+1 decimal), Bi-directional total active energy measurement ,reverse

    active energy measure in the total active energy

3. Product self-design has function of lighting protection

4. Overvoltage protection, under voltage protection and overcurrent protection can select auto-

    Reclosing mode or manualReclosing mode

5. In case of over-voltage fault, under-voltage fault or over current fault in single phase line, the

    product can power off the line and can automatically restore connecting the line over a time

    delay after voltage of the line is recovered to normal condition.

6. In case of transient over voltage in line, the product can protect the equipment from false

    operation.

7. In case that the line subjects to unstable voltage or sudden power-off and power-on due to

    loosened connection and other fault, the product will disconnect the line.

8. When fault voltage of the line reaches the peak, the product itself will not be damaged.

9. Under over-current protection mode, you also can select Malignant load protection (Pure

    Resistive Load limit) which is used for Apartments and Student Dormitories electric safety

10. You can select the circuit output cycle switch on/off mode

11. Led indication of overvoltage protection, under voltage protection and over-current protection

12. Diversified design for the protection, you can closed t any one of overvoltage protection,

    under voltage protection and over current protection in any time
