Advanced Power Quality Analyser & Power Meter

Description

The PM175 PRO power quality analyzer merges the trusted design of PM17x legacy models with the advanced functionality of the PRO Series.

This powerful combination is presented on a bright LED display and is further enhanced by unique features, including an IRIG-B input and a fourth voltage input (V_ref).

Featuring multiple protocols (IEC 61850, DNP3 and IEC 60870-5-101/104) and dual-port ethernet, it is the ultimate solution for power monitoring, meeting and exceeding current requirements in utility and industrial applications.

LPIT Sensor interface

The PM175 PRO provides interface with a variety of commercial LPIT sensors designed for MV metering. This unique application is available for both PT/CT inputs.
