Three phase three wire one meter multi card, irrigation meter, public meter

Brief introduction

A new type of three-phase electronic prepaid energy meter with multiple functions such as energy metering, load control, and user information managementICThe card type prepaid energy meter is an ideal product for the current reform of the electricity system, realizing the commercialization of electricity, solving the difficulty of charging, and regulating the load status of the power grid. There are two connection methods for this series of three-phase electronic energy meters: direct connection or connection through a transformer. The product meets all performance indicatorsGB/T18460.3-2001andGB/T 17215.321-2008All technical requirements for three-phase electronic prepaid energy meters in the standard.

2、 Function and Features

1. Measuring three-phase active energy, long-term operation does not require calibration;

2. Three phase power supply, if any two of the four wires of the three-phase four wire energy meter are disconnected, the measurement accuracy will not be affected;

3. Equipped with phase failure indication function or voltage indication function;

4. Capable of outputting electrical energy testing signals.

5. One household, one card, with good anti-counterfeiting properties;

6. When the remaining battery level is equal to the alarm battery level, the digital display will keep on, reminding users to purchase electricity in a timely manner;

7. The remaining power is0Time trip and power outage;

8. Automatic power outage for overload, facilitating the implementation of capacity expansion by the power department;

9. Equipped with data write back function for easy management by the power department;

10.The load switch is installed externally and controlled internally by a relay (with a contact capacity of)250VAC/5A）；

11.matchedICThe card sales electricity management system has complete functions such as electricity sales management and electricity monitoring.
