| Functions and features | |||||||||||||||
| ● 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. ● Ten pole width (Modulus 12.5mm), complying with standard JB/T7121-1993. ● 6 digits display (999999kWh) by step motor type impulse register. ● Standard configuration one port of pulse output passive (polarity), May select increase a distant port of pulse output passive (nonpolarity), (Product Configuration code is DF). And contact with all kind of AMR system conveniently, Complying with standard IEC 62053-31 and DIN 43864. ● Four LED instructions respectively power supply state and signal energy impulse. ● Automatic detection the direction of the flow of load current. And Instructions on individual LED ● 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. ● May select two components measure three phase three wire active energy (Product Configuration code is EH) or two phase three wire active energy (Product Configuration code is EG). ● Direct connect operation, type S wiring (Inlet from bottom, outlet from top). ● Short terminals cover, in order to reduce mounting space, and make mounting conveniently. |
