1. General Description

       DDS238-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 .

 2.Product features

2.1 LCD display with backlight , can display total active energy (kWh) , real time current (A) , voltage(V) ,  active power (W) , temperature(℃)

2.2 LCD display kWh (4 digital+1 decimal) , Bi-directional total active energy measurement ,reverse active energy measure in the total active energy

2.3 Product self-design has function of lighting protection

2.4 Overvoltage protection, under voltage protection and over-current protection can select auto-Reclosing mode or manual–Reclosing mode

2.6 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 lien is recovered to normal condition.

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

2.8 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.

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

2.10 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

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

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

2.13 Diversified design for the protection , you can closed t any one of  overvoltage protection, under voltage protection and over-current protection in any time
