Main Usages:
This kind of meter integrates many functions into one, realizes the functions of time-sharing electricity measurement for active double-direction, measuring demand, sinusoidal reactive, calculating power factor, displaying and tele-transmitting present voltage, current, power and load curve etc. and it realizes the function of recording all the missing voltage, missing current and the percent of pass for voltage, the function of displaying, these functions prevent the tamper effectively, and meet the requirements of power supply department for scientific management, it can be widely used in power plant, substation,1 measuring customs and all the enterprises.
This kind of meter can be installed GPRS module (installed inside or providing outside), wireless module, GSM module and solving the remote meter reading channel according to the requirement of the customer. It expands the function of the meter.
Main Functions:
1. Measuring function: measuring electricity, measuring demand, measuring voltage, current and power, and measuring power factor function.
2. Alarming missing voltage, missing current and displaying and recording function.
3. Alarming over-limit voltage and displaying and recording function
4. Alarming over load function
5. Recording networks parameters function
6. Recording affairs parameters function
7. Remote programming and meter reading function
8. Meter reading function at power off
9. Copying function
10. Remote controlling function (only apply to GPRS communicating module meters)
Main Characteristics:
1. High accuracy, high overload, high reliability, low power consumption, small volume, light in weight and good structural performance.
2. The internationally advanced integration circuits specially used for Watt-hour Meter, permanent information keeping non-volatile memory and other hardware and software measurements are employed to prevent the meter from losing data at times when both AC power supply and internal support battery lost voltage.
3. STN, LCD of wide temperature range gives a clear and full view information.
4. Management software with friendly user's interface is reliable and easy-to-learn.
