Function
features:
★
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
★
Long range of operating voltage, current and operating temperature
★ Low
power consumption, high integration level, high cost performance
★ Measure
active and reactive power(four-quadrant)
★ Record
voltage, current, instantaneous power,
power factor,
apparent power,
real-time frequency
★ Measure
for each phase
★ Large
LCD displayed in Chinese
★
Active/reactive multi tariff, can programme to set the tariff and period of time
★
Record opening the cover, record events
★
Display at power failure
★ Display
in turn function. The time interval can be set by infrared or RS485
★
Clock function. The clock can be checked by infrared or RS485
★ Adopt
long-lived lithium battery, the life of the battery is more than 15 yearsTechnical
