ENA510 (PMU + PQA)

Model ENA510 is built in a rugged plastic PELI case. The analyzer has a durable construction useful for field measurements. It allows monitoring of one or two three-phase voltage and current systems. Currents are measured using current clamps.
The analyzer can be controlled via a built-in touch screen with surface hardness 7H (diamond has 10H). Access to the analyzer can be done remotely using Ethernet or Wi-Fi too.

The analyzer is equipped with a remote GPS signal receiver for precise time synchronization and phasor measurement according IEEE C37.118.
Additionally the analyzer has 16 digital inputs (24 V).

Available models of ENA510:

  • 1x 4U + 1x 4I
  • 1x 4U + 3x 4I
  • 2x 4U + 2x 4I
  • 4x 4U
