Application
ZMM75SF single phase electronic DIN-rail multi-tariff intelligent energy meter uses microelectronic technology to measure electric energy, and meets the GB/T17215.321-2008, GB/T18460.3-2001 and DL/T614-2007 standard electric meters, adopting Fully shielded, 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 It has the characteristics of long life, small size, beautiful appearance and convenient installation.
The meter is applied to the computer management, and the electricity is purchased first. The maximum operating power can be limited within the rated current range (defined by the power supply department). The electric energy meter can be RS485 communication remotely sold, or the IC card can be sold. The IC card has one meter and one card, and the special card is used. The lost card does not lose power and the 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.
ZMM75SF series electric 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 ambient temperature of -30 ~ 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.
Main Technical Data
1.Specification
2.Basic error
3. Startup
Under the condition that the rated voltage, rated frequency and power factor are 1.0, the starting current of the meter is 0.004Ib for the level 1 and 0.005Ib for the level 2.
4. Latency
When there is no current on the line of the meter, and the voltage applied to the line is 115% of the rated value, there is no more than one output pulse.
5. Power consumption: ≤ 1.5W, 10VA
