Summarize
Single-phase multifunctional power meter can measure the power
parameters used in single-phase power grid system with high
precision: single-phase voltage, current, active power, reactive
power, power factor, grid frequency, active power, reactive power,
and with communication interface and power pulse output function.
Using MODBUS-RTU communication protocol, LED field display and
remote RS-485 digital communication are realized. It has the
characteristics of easy connection and installation, simple wiring,
convenient maintenance, small engineering amount, field
programmable setting input parameters, etc., and can complete the
networking communication with different PLC and industrial control
computers in the industry.
