1.Stable measuring accuracy,

2.Bi-directional measuring function

3.Reserve data without back-up battery.

4.Register driven by single chip to avoids data inconsistency

5.Adoption of optical coupling isolated passive pulse output interface .

6.Featured with wide load range, high accuracy, high reliability, high sensitivity, straight error curve, low power consumption, small volume, light weight, energy saving, material saving, direct register display, etc.

Working Principle

Wiring diagram

1.Starting: under conditions of reference voltage,reference frequency and power factor is 1.0, the meter should be able to start and measure the electric energy normally when meter of class 1 is 0.4%Ib and meter of class 2 is 0.5%Ib.

2.Creeping: anti-creeper logical design, apply a reference voltage of 1.15 times to the voltage circuit, while there is no current in current circuit, testing output of the meter shall not produce more than one pulse.

3.Power consumption: ≤2W (10VA).

4.Ambient conditions Standard working temperature: -25℃～55℃

     Limiting working temperature: -25℃～60℃ 

     Note: limiting working temperature for special requirements: -40℃～70℃
