Three 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
It can achieve forward and reverse metering of three-phase active and reactive energy, and has power direction indication function. It can also measure electrical measurement parameters such as three-phase voltage, current, active power, reactive power, and power factor
It can achieve forward and reverse metering of three-phase active and reactive energy, and has power direction indication function. It can also measure electrical measurement parameters such as three-phase voltage, current, active power, reactive power, and power factor. Electric energy is accumulated according to total, peak, average, and valley, respectively
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 30minutes between time period
It has the functions of data rotation display and data key display, 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
Passive optoelectronic isolation output port, pulse width: 80ms ± 20ms
Communication interface: RS485; Communication protocol: DL/T645-2007 (customizable MODBUS-EVEN); Communication speed: DL/T645-2007 2400bps (default) parity check; MODBUS-EVEN 9600bps (default) parity check; 4800bps, 2400bps, and other options are available
By using RS485 to form a wired or wireless network for remote automatic meter reading, remote power sales, and remote switching, intelligent management of electricity consumption can be achieved
