Function
features:
★
Adopt overseas advanced digital processing bidirectional power,specialized energy metering
IC and SMT technology
★ High accuracy, high reliability,exact measurement
★
Prevent from stealing electric energy, low power consumption, low cost
★
Measure and count bidirectional power,needn't adjust for a long working time
★
Three-phase power supply, the accuracy of measurement will not be affected when one or two
phase electricity is cut off
★
Prompt the lack of phase(for choice)
★ Ensure
passage of all the tests for electromagnetic compatibility
★
Long range of operating voltage and current Technical
