DTSYU866 / DSSYU866 Three phase rail type prepaid energy meter (with infrared communication 485)

Overview

The DTSY866 single-phase electronic rail prepaid energy meter (hereinafter referred to as the meter) uses microelectronics technology to measure electrical energy and complies with the GB/T17215.321-2008 and GB/T18460.3-2001 standards. It 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 meter calibration, anti-theft, high overload, long life, small size, beautiful appearance, and easy installation.

Electricity meters should be managed by computers and used after purchasing electricity. The maximum operating power can be limited within the rated current range (limited 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.
