RS485 energy meter three phase four wire inductive for household with digital display
Function And Features:
1.35mm standard DIN rail installation, complying with standard DIN EN50022. Or frontboard installed (mounting holes center distance 63 mm), users can choose any one by themselves.
2. Ten pole width (Modulus 1 2.5mm), complying with standard J B/T71 21 -1 993.
3. Have three tariffs, may select 12 daily period of times. You can set the date arbitrary which can automatic read the meter every month.May select single tariff function in weekend. (Please specified when ordering)
4. There are a clock and Maintenance-free backup lithium batteries in it. Battery capacity detection and display all the time.It can keep the electricity data for 12 months.The data can be kept forever after blackout.
5. May select cycle display (default) or push the button itemized display, we can set the cycle display, it can display 14 data at most. Can select the data displayed. The decimal displayed can choose set one or two.
6. There are a polarity port of pulse output passive closed and a no polarity port of pulse output passive distant, the output rate is 10 or 100 imp/kWh (can select),Comply with standard IEC62053-31 and DIN 43864.
7.There are far infrared and a port of RS485 communication data for setting and reading the meter.Set and operation have password protection, communicationagreement complying with standard D L/T645-1 997.
8.Ten LED instructions respectively power supply state, signal of energy impulse, the direction of the flow of load current, the tariff state just now and the data communications state.
9.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 .
10.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 AN) and PT & CT (Product Configuration code is AP) for operation.
11.Standard configuration short terminals cover, may select extension terminals cover, it is for protecting use electrical safety. (Product Configuration code is AM).
