Specifications
It has function of carrier communications, relay control, withADE7755 chip, high integration.high measurement accuracy, etc.
Functions and features
1) Each of four periods has different rates(point period, peak period, smooth period and trough period). Every period of time can be programmed into 12 periods of time and the minimum time interval is one minutes.
2) All the consumption date can be reserved for 12 months.
3) It can auto identify the directional, will be auto save and accumulate to the forward direction power counter. It can auto save the reverse direction power, starting time and the total time.
4) It has the function of reverse directional pulse test and indication.
5) It has the isolated RS485 commuication, and design for prevent from the lightning strike.
6) Date-copying adopt the password and program switch protection, recording the latest program time and degree.
7) It adopts the hardware clock circuit, the lowest current consumption, The battery is one-time and environmental protection lithium battery.
8) It can setup the meter number, bureau number, time-period, rate, date, time, meter reading time, password and the initial electric power.
9) It can indicate the short voltage of the backup battery, the hardware state of the meter, the communication state of the meter, the clock state, the directional electricenergy, time-adjusting state and present time-period.
10) It can read via RS485 or hand computer.
11) Meter reading function at power off.
