Summarize
Multi-function power meter can measure the power parameters used in
three-phase power system with high precision: three-phase voltage,
current, active power, reactive power, power factor, power factor,
power factor, power factor, power factor, power factor, power
factor, power factor, power factor, power factor, power factor.
Power grid frequency, active power, reactive power, and with
communication interface and power pulse output function. Using
MODBUS-RTU communication protocol, LCD 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.
Peculiarity
Measurement: three-phase voltage, current, active power, reactive
power, power factor, frequency, active power, reactive power
display: three rows of LCD digital tube display, high visibility
Communication: RS485 communication, MODBUS-RTU communication
protocol
Output: two power pulse output (pulse constant 3200imp/kwh)
Expansion: can directly input signal from current, voltage,
transformer, field programmable setting of input parameter ratio
Use: incoming line, bus and important distribution loop, using GCS,
GCK, MNS, GGD and other cabinet types
