Single-phase multi-rate electric energy meter

Detailed Product Description

Product Brief introduction

 

Single-phase multi-tariff electric meter/energy metering/electricity meter adopts advanced microelectronics technique and SMT manufacturing technology, its performance conforms to IEC62053-21 standard. This product is used for measuring single-phase AC active electric energy with rated frequency of 50Hz or 60Hz, it also owns many advantages as high precision ,high sensitivity ,reliable performance, wide load, low power consumption, small volume etc.

 

Function 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 five minutes.

2. All the consumption date can be reserved for 12 months

3. It can automatic identify the directional, will be automatic save and accumulate to the forward direction power counter. It can automatic save the reverse direction power, starting time and the total time.

4. It has the function of reverse directional pulse test and indication

5. Electric isolated RS485 communication, have the design of prevent from thunder stroke.

6. When read a data, it has double protection of password and programmed switch, recording the latest programmed time and degree automatically

7. It adopt the hardware clock circuitry, low current consume and adopt imported one-off green environment-friendly 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 battery, the hardware state of the meter, the communication state

The meter, the clock state, the power direction, time adjusting state and the present time-period. It can read via RS485 or hand computer.

10. Energy meter can change month during the day of automatic reading data meter in the period of power Cut
