Application

ZMM75SY single-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. Using 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. The electric card can transmit data in two directions, and can automatically power off the alarm to call the user to purchase electricity. When the power is zero, the power is automatically turned off, and there is a certain anti-stealing software design.
ZMM75SY series electronic energy meter is suitable for frequency 50HZ or more or 60HZ active energy metering, and is installed in indoor and outdoor meter box. Applicable to the ambient temperature of -35 ~ 80 ° C, relative humidity does not exceed 85%, and the surrounding air should not have corrosive gases, to avoid dust, salt spray, condensation and other effects.
