Summarize
The multi-function harmonic meter can measure the power parameters
used in the three-phase power system with high precision:
three-phase voltage, current, active power, reactive power, power
factor, grid frequency, active power, reactive power, power quality
analysis, and with communication interface, four-way switching
input, four-way switching output, and four-way analog output
functions. Local or remote switch signal monitoring and control
functions can be 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.
