summary:

The DDSYU5881-LK single-phase electronic rail prepaid energy meter (hereinafter referred to as the meter) uses microelectronics technology to measure 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.

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.

DDSY866-LThe series of electronic energy meters are suitable for measuring active energy with a frequency of 50Hz or more or 60Hz, and are 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.

Functional features:

1. Equipped with IC recharge management;

2. Measuring active electricity: total electricity and electricity, remaining electricity;

3. Record the latest purchased electricity display alarm amount, power outage alarm amount, and hoarding amount;

4. Communication function: The electricity meter has RS485 communication function.

5. Remote power on/off function

6. Can support remote recharge (standard DL/T645- (1997) 2007 protocol);
