Features

This product is a clamp-type power quality analyzer that supports a
variety of wiring systems. It simultaneously performs simulations of
instantaneous values, integrated values, demand values for power
management, harmonic analysis, power quality events, and phase lead
capacitor values for improving the power factor. Voltage and current can
be displayed as waveforms and vectors.
Measured data can be saved to files in SD memory cards or internal memory,
and the files can be transferred to a PC through USB communication.
Safety Design
This product complies with safety standard IEC 61010-1 CAT. IV 300V/
CAT. III 600V/CAT. II 1000V.
Power Quality Measurement
This product supports international power quality measurement standard
IEC61000-4-30 Class S. It can perform highly accurate frequency
and rms voltage measurements and harmonic analysis as well as
simultaneously measure without gaps swell, dip, interruption, transient,
inrush current, and flicker that are necessary for capturing and monitoring
power abnormalities.
Power Measurement
This product can measure active, reactive, and apparent powers as well
as watt-hour, power factor, rms current, phase angle, and neutral line
current.
Wiring Systems
This product supports single-phase two-wire (four systems), single-phase
three-wire (two systems), three-phase three-wire (two systems), and
three-phase four-wire measurement lines.
Demand Measurement
You can monitor in a simplified form the usage condition so that the
specified target value (contract demand) is not exceeded.
