Overview

DDSY193The single-phase electronic rail prepaid energy meter (hereinafter referred to as the meter) uses microelectronics technology to measure electrical energy, which complies withGB/T17215.321-2008andGB/T18460.3- 2001A standard electric meter adopts a fully shielded and sealed structure, and uses an advanced microcontroller processing system for data acquisition, processing, and storage. It has good resistance to electromagnetic interference, low self consumption and energy saving, high precision without calibration, anti-theft, high overload, long life, small size, beautiful appearance, and easy installation.

Electricity meters should be managed by computers, and electricity should be used after purchase. Within the rated current range, the maximum operating power can be limited(Restricted by the power supply department)One card, one meter, dedicated card, no power loss after card loss, can be used after card replacement. Electric cards can transmit data bidirectionally and automatically power off to alert users when purchasing electricity. When the battery level is zero, it automatically shuts off the power and has a certain anti-theft software design. The electric meter hasRS485Communication function. comply withDL/T 645-（1997）2007Communication Protocol for Multi functional Energy Meters and Power Industry Standards of the People's Republic of ChinaDL/T 698-1999The requirements of the Technical Conditions for Centralized Meter Reading System for Low Voltage Power Users.
