DTSYU866 / DSSYU866 Three phase rail type prepaid energy meter (7P)

Overview

The DTSY866/DSSY866 three-phase electronic rail prepaid electric energy meter (hereinafter referred to as the electric meter) uses microelectronics technology to measure electric 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 calibration, anti-theft, high overload, long life, small size, beautiful appearance, and easy installation.

Features

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.

The electric energy meter is suitable for measuring active energy with a frequency of 50Hz or more or 60Hz, and is installed in indoor and outdoor meter boxes for use. Suitable for environments with temperatures ranging from -35 to 80 degrees Celsius, relative humidity not exceeding 85%, and no corrosive gases in the surrounding air to avoid the effects of dust, sand, salt spray, condensation, etc.
