Single phase 4G, NB lot, WiFi, and 485 remote prepaid electricity meters are the new generation of miniature intelligent electricity meters launched by our company based on years of experience in meter design
This series of instruments adopts high-definition segmented LCD display, which can be used to set parameters such as clock, tariff period, and has the function of outputting electric energy pulses; It is possible to exchange actual data with the upper computer through NB · loT, WiFi, GPRS, and RS485 communication interfaces, achieving remote meter reading, remote control of opening and closing functions, and remote prepaid recharge functions, greatly facilitating automatic management of electricity consumption
Function and Characteristics
It can measure single-phase active positive and negative electrical energy, as well as reactive positive and negative electrical energy. It can also measure electrical parameters such as voltage, current, active power, reactive power, and power factor.
Can measure single-phase active positive and negative phase electrical energy; The measurement of reactive positive and negative electrical energy, and the measurement of electrical parameters such as voltage, current, active power, reactive power, power factor, etc; The electricity is accumulated separately by total, peak, flat, and valley.
Clock error within 0.5s/day, with automatic switching functions for calendar, metering, and leap years.
Programmable settings for two time zones per year, two time period tables, 12 day time periods, and four rates for peak, peak, flat, and valley, with a minimum interval of 30 minutes between time periods.
It has the functions of data rotation display and data key display, and can query all display items through the page turning button on the panel. It can be set to wheel display mode, and the default wheel display time is 4 seconds.
Active energy pulse output, used for meter calibration and remote energy collection.
Passive optoelectronic isolation output port, pulse width: 80ms ± 20ms.
