| 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. 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. 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 100imp/ kWh, can select). Complying with standard IEC 62053-31 and DIN 43864. 5. 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. 6. Six LED instructions respectively every power supply state, signal of closed energy impulse and distant energy impulse and data communication state. 7. Automatic detection the direction of the flow of load current. And Instructions on individual LED 8. 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. 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 CT (Product Configuration code is FC) and PT & CT (Product Configuration code is EC) for operation. 10. Standard configuration short terminals cover, may select extension terminals cover, in order to protect to use safety. (Product Configuration code is GF). |
