Detailed description
Ⅰ.Features：
⊙ True RMS metering:
Measure all the
electric parameters such as voltage,current,frequency,active/reactive/apparent
power,power factor and etc.
⊙MONITORING:
1.power quality
2.Voltage harmonics 2-31st
3.Current harmonics 2-31st
4.Voltage crest factor
5.THFF(TIF)
6.Current k factor
7.Voltage unbalance factor
8.Current unbalance factor
9.Max/Min statistics with time stamps
⊙Communication:
standard RS-485 communication interface,which supports
Modbus-RTU protocol;
⊙I/O optional module:
A maximum of 3 modules can be used for one meter.
Digital input,digital output,pulse output,reply output, analog output are
provided by I/O option module.
ALARM:
Alarm contact for over voltage,under voltage,over
current.
⊙Harmonic:
the meter
measures component harmonics 2-31st inst and THD for both current
and voltage.
⊙time of use:
user can assign up to 4 different
tariffs(sharp,peak,valley and normal) to different time periods within a day.
