Elcom Network Analyzer model ENA400
Characteristics:
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 uo 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 on and store analog quantities, together, with digital data.
ENA400 analyzer fully complies with the IEC 61000-4-30 standard, class A.
