LoRaWAN SINGLE-PHASE ELECTRICITY METER

Category

● Time-sharing metering: Accumulates active electric energy based on time periods and stores total, peak, flat, and valley energy ● Prepayment functionality: Remote electricity sales through RS485/LoRaWAN/NB module, with low-balance alerts and overdraft limit feature ● Measurement and monitoring: Measures, records, and displays parameters (e.g. voltage, current, and power factor with an error margin of ±1%.) ● Timing function: Temperature compensation, automatic calendar, timing, and leap year conversion

LoRaWAN SINGLE-PHASE ELECTRICITY METER

HKT single-phase fee-controlled intelligent watt-hour meter is a new generation of energy metering products. This product adopts the special large-scale integrated circuit and SMT production technology, and has the functions of power metering, data processing, real-time monitoring, automatic control, information interaction and so on.

Features of LoRaWAN Single-phase Electric Meter

  • Metering: It has the function of time-sharing metering, and the active electric energy is accumulated according to the corresponding time period, and the total, peak, peak, flat and valley electric energy is stored.
  • Prepayment: The watt-hour meter can sell electricity through the remote 485 or LORAWAN/NB module. When the electricity quantity is lower than the alarm value, the user is reminded to purchase electricity in a display mode; It has the function of overdraft limit.
  • Measurement and monitoring: It can measure, record and display the voltage, current, power factor and other operating parameters of the current watt-hour meter. The measurement error shall not exceed ± 1%.
  • Timing function: Built-in hardware clock circuit with temperature compensation function is adopted, which has automatic conversion functions of calendar, timing and leap year.
