Accurate energy measurement is critical to the reliable operation of EV charging infrastructure. Using standard reference systems, test adapters, and portable test units, we enable certified testing of EV charger meters to ensure compliance with international standards and regulatory requirements.

Precise verification prevents systematic overcharging of consumers and mitigates undetected power losses for utilities, ensuring both sides are protected. With the rapid rollout of EV charging networks under green energy and net-zero carbon initiatives, certified meter testing is an essential step in commissioning and maintaining high-performance EV chargers.

PWS 2.3 genX

The PWS 2.3 genX Portable Working Standard is a three-phase portable electronic meter test unit of accuracy class 0.1, used for testing single and three-phase electricity meters on site. The PWS 2.3 genX allows checking of all meter installation parameters and associated circuits.

PWS 3.3 genX

The PWS 3.3 genX is a combination of a Portable Working Standard of class 0.05 % and an IEC 61000-4-30 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 addition of a battery pack keeps the device running in the event of interruptions in the supply voltage.
