ENA330 (PQA)

Power quality analyzer ENA330 is a compact, display-less instrument with 4 voltage and 4 indirect current inputs designed to process signals from external current clamps. The ENA330 contains a powerful embedded PC and uninterruptible power supply for approx. 1 minute of operation.

Due to its low profile, ENA330 is ideally suited for mounting inside shallow switching cabinets. Users perform instrument configuration and control via USB or ethernet using the provided remote control software installed on an external PC. ENA330 can be ordered with several optional internal memory sizes for storing up to several months of data.

ENA330 analyzer fully complies with the IEC 61000-4-30 standard, class A.
