Functions and features |
1. 35mm standard DIN rail installation, complying with standard DIN EN50022. Or front board installed (mounting holes center distance 63 mm), users can choose any one by themselves. 2. Ten pole width (Modulus 12.5mm), complying with standard JB/T7121-1993. 3. Standard configuration 6 digits display (999999kWh) by step motor type impulse register. May select 7 digits display by impulse register (Product Configuration code is DK). 4. There are a polarity port of pulse output passive closed and a nonpolarity port of pulse output passive distant, the output rate is 10 or 100 imp/kWh (can select). And contact with all kind of AMR system conveniently, Complying with standard IEC 62053-31 and DIN 43864. 5. Five LED instructions respectively every power supply state and signal of closed energy impulse and distant energy impulse. 6. Automatic detection the direction of the flow of load current. And instructions (signal of closed energy impulse is green when working, that is meaning the direction of the flow of load current reverse). 7. Single direction three components measure three phase four wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21. 8. May select two components measure three phase three wire active energy (Product Configuration code is DH) or two phase three wire active energy (Product Configuration code is DG) 9. Standard configuration type S wiring (Inlet from bottom, outlet from top) for direct connect operation, we can also choose another type of wiring, and use 5+1 digits display by impulse register, CT (Product Configuration code is CI) and PT & CT (Product Configuration code is BI) for operation. 10. Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is DF). |
