product details

Product Introduction

The DTSY/DSSY series electronic three-phase prepaid energy meter is a new type of IC card prepaid energy meter with multiple functions such as energy metering, load control, and user information management. This meter is an ideal product for the current reform of the electricity system, the commercialization of electricity, the solution to billing difficulties, and the regulation of power grid load status. There are two connection methods for this series of three-phase energy meters: direct connection or connection through a transformer. The performance indicators of this product comply with all technical requirements for electronic three-phase prepaid energy meters in GB/T 7215.321-2008 "Level 1 and Level 2 Static AC Active Energy Meters" and GB/T 189460-2001 standards.

Function and characteristic

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

● Three phase power supply, with one wire (any one of the three wires of a three-phase three wire energy meter) or two wires (any two of the four wires of a three-phase four wire energy meter) disconnected, the measurement accuracy is not affected;

Purchase electricity first and then use it. Multiple meters and cards in the same area can be used for inserting cards and disconnecting power when unplugged. The power consumption can be automatically deducted, and when the power is zero, the power will be automatically tripped and disconnected. It also has a certain anti-theft software design

The power purchase card adopts SLE4442 encrypted 1C card, and each power purchase card has _ random passwords to prevent forgery:

● Anonymous purchase of electricity cards; Cannot report loss; Cannot replace card, users should keep it properly to prevent loss. The power purchase card can be used repeatedly to purchase electricity within the same area;

The load switch is installed externally and controlled internally by a relay (with a contact capacity of 250VAC/5A) or a built-in relay for power-off control

The supporting IC card electricity sales management system has complete functions such as electricity sales management and electricity monitoring;
