Competitive Advantage

1. Front board three fixed installation, up and down mounting holes center distance is 198-212 mm, users can choose any one by themselves.

2.Voltage components and current components, using double insulation structure, have good electrical characteristics.

3.Active single-phase electric power metering,no subject to adjust in terms of long working;

4. 6 digits display (999999KWh) by step motor type impulse register.

5. Standard configuration only a polarity port of pulse output passive, may select add a nonpolarity port of pulse output passive distant (Product Configuration code is DF). And contact with all kind of AMR system conveniently,Complying with standard IEC 62053-31 and DIN 43864.

6. Four LED instructions respectively power supply state and signal of energy impulse.

7. Standard configuration dont detection direction of the flow of load current. May select automatic detection the direction of the flow of load current. And instructions on individual LED. (Please specified when ordering)

8. Single component measures single-phase two-wire active energy consumption,Complying with standard IEC62053-11.

9. Direct connect operation, two types wiring optional, standard or special one with CT

10.Standard configuration short terminal cover, which is helpful to reduce installation space and make it convenient to install; May select extended terminal cover, which is for protecting the safety of using electricity.
