The PWS 3.3 genX is a combination of a Portable Working Standard of class 0.05 % and an IEC *****-*-** Class A compatible Power Quality Analyzer with 4 voltage (U1, U2, U3, UN, UPE) and 4 current channels (direct: I1, I2, I3 and via clamp-on CT: IN / IPE Neutral current / Protection Earth current).

The modular concept of the PWS 3.3 genX allows the extension of the direct current measurement range from 12A up to 120A and the adding of a battery pack keeps the device running in the event of interruptions in the supply voltage during Power Quality recording or when supply from measuring voltage.
