| ● 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. ● May select 6+1 digits display (999999.1kWh) or 5+2 digits display, it can be arbitrary set by users from far infrared or port of RS485 data communication. ● 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 100imp/kWh, can select). Complying with standard IEC 62053-31 and DIN 43864. ● There are a port of far infrared data communication and a port of RS485 data communication. Standard configuration communication agreement complying with standard DL/T645-1997, can also choose any other communication agreement. ● Five LED instructions respectively power supply state (phase voltage L1 & L3), signal of closed energy impulse and distant energy impulse and data communication state. ● Automatic detection the direction of the flow of load current. And Instructions on individual LED ● Single direction two components measure two phase three wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21. ● 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 CT (Product Configuration code is FA) and PT & CT (Product Configuration code is EA) for operation. ● Standard configuration short terminals cover, may select extension terminals cover, in order to protect to use safety. (Product Configuration code is GD). |
