ENA440 (PQA)

Power quality analyzer ENA440 consists of a PC in a compact metal case and an external signal conditioning kit (ENA-SCM-01A). ENA-SCM-01A kit provides signal conditioning for up to 16 analog signals and optional digital inputs (up to 64). Digital inputs are sampled synchronously with analog inputs. The total number of voltage and current signals can go up to 16 (e.g. 5 x 3U or 2x 3U+3I).

ENA440 is the best solution for customers, who are looking for a permanently installed Power Quality analyzer to monitor multiple 3-phases power systems. ENA-Node firmware module fault recorder and transient recorder can trigger and store analog quantities together with digital data.

ENA440 analyzer fully complies with the IEC 61000-4-30 standard, class A.
