ENA400 (PQA)

ENA400 power quality analyzer is based on an industrial PC in a 19" case and up to 2 external signal conditioning kits (ENA-SCM-01A). One 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 32 (e.g. 5 x 3U+3I).

ENA400 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.

ENA400 analyzer fully complies with the IEC 61000-4-30 standard, class A.
