Using special metering, measuring bi-directional active
and four quadrants reactive electric energy
Main components used good-quality, designed for
electronic type electric energy meter design special
components
RS**5 communication interface using independent power
supply and with anti-static and surge protection circuit
Using high stability, low power consumption, with
real-time temperature compensation of high precision real
time clock, can ensures that natural environment within one
year of real time clock error is less than 2 minutes
Cost control mode: virtual medium
Main function: measurement of electric energy remote
control function, cost, display, clock period and rate
function, calibration, measurement and monitoring, event
recording, freezing, power meter, data storage, reset,
communication, pulse output, load control, parameter settings
and security authentication
Communication: RS**5, infrared (standard) and
carrier-wave
Shell adopts modular design, firm structure, flame
retardant, aging resistance, good sealing performance and
functions can be extended
