Zhuhai Guoce Electric Energy Instrument Technology Co., Ltd
No. 4, Third Street, Cuizhu Industrial Zone, Qianshan, Zhuhai City, Guangdong Province
| Functional Features |
35mm DIN standard rail installation, in compliance with DIN EN 50022 standard. Standard configuration: Passive power pulse output.
Three phase active and reactive energy measurement and display of three-phase voltage, current, active energy, and reactive energy.
Voltage signal power supply, no auxiliary power supply required.
Prepaid fees
By adopting a pay before use policy, users can purchase a certain amount of electricity in advance before using it. When the electricity is used up, the meter will automatically cut off the power to prevent overdue electricity bills.
postpaid
To ensure the power supply of key users, the energy meter can be set to operate in power protection mode. After setting the power guarantee, the electricity meter will not automatically cut off the power if there is any arrears, and users can pay again after using the electricity.
metering function
A has the function of measuring positive and negative active energy;
Measurement of reactive energy for combination reactive power 1 and combination reactive power 2;
C supports multiple rate measurement (optional).
D supports hourly freezing, timed freezing, daily freezing, and scheduled freezing functions (optional);
display function
A supports displaying multiple parameter interfaces;
B has automatic parameter rotation display function;
communication
The electric meter has one RS485 interface, which is electrically isolated from the inside of the meter and designed with lightning protection circuit;
output function
Has active and reactive power test pulse output.
Event recording function
Real time measurement of effective values such as voltage, current, power, and current frequency;
B has recording functions such as programming and timing.
Equipped with remote recharge and remote closing function (optional)
Implement remote power on/off function of the energy meter by sending instructions through the main station backend.
