DDSYU5881-CK single-phase rail type prepaid electric energy meter (4P)

Product Overview:

summary:

DDSYU5881-CKThe single-phase electronic rail prepaid energy meter (hereinafter referred to as the meter) uses microelectronics technology to measure electrical energy, which complies withThe electric meters according to GB/T17215.321-2008 and GB/T18460.3-2001 standards adopt a fully shielded and sealed structure, and use advanced single-chip processing systems for data acquisition, processing, and storage. They have good resistance to electromagnetic interference, low self consumption and energy saving, high precision without calibration, anti electricity theft, high overload, long service life, small size, beautiful appearance, and easy installation.

Functional features:

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