Product Description

Integra 1630 digital metering system provides high accuracy of 0.2% measurement, display, and communication of all major electrical and power quality parameters, including total harmonic distortion (THD) measurement up to the 31st harmonic.

To suit multiple applications, the INT1630 measures single-phase, three-phase-three-wire, and three-phase four-wire circuits, all selectable at the point of installation.
