Application

ZMM1250SY three-phase electronic rail prepaid electric energy meter uses microelectronic technology to measure electric energy. It complies with GB/T17215.321-2008 and GB/T18460.3-2001 standard electric meter, adopts fully shielded and fully sealed structure. Use advanced single-chip processing system for data acquisition, processing and storage, with good anti-electromagnetic interference, low self-consumption and power saving, high precision, no need for calibration, anti-stealing, high overload, long life, small size, beautiful appearance Easy to install and so on.
The meter is applied to the computer management, and the machine uses electricity after purchasing electricity. The maximum operating power can be limited within the rated current range (defined by the power supply department). One card and one meter, and the card and the use, the lost card does not lose power, the replacement card is reused.
