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. 6 digits display (999999KWh) by step motor type impulse register.
3. 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 DI). And contact with all kind of AMR system conveniently, Complying with standard IEC 62053-31 and DIN 43864.
4. Four LED instructions respectively power supply state and signal of energy impulse.
5. Standard configuration don’t 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)
6. Single direction three components measure three phase four wire active energy consumption. It is nothing with direction of the energy of load current. Complying with standard IEC 62053-21.
7. Standard configuration direct connect operation , type 16B wiring, we can also choose another type of wiring, and use 5+1 digits display by impulse register, CT (Product Configuration code is DV) and PT & CT (Product Configuration code is DX) for operation, it is type 48B wiring.
8. Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is EI).
