KPM75 Power Quality Analyzer
KPM75 is the advanced power quality analyzer that follow international power quality standards and monitor all power quality parameters such as flicker, short interruptions in recorded voltage, and harmonic up to 63rd measurements with power data Statistics, IO signal control alarm, communication and other functions.
It’s mainly used in main line to monitor the incoming line grid power quality online in real time.
