EN50160 Power Quality Analyzer

The PM175 is an analyzer providing the full range of power quality monitoring and reporting, according to the EN50160 standard.*

Equipped with built-in digital I/Os and a serial communication interface supporting SCADA-driven protocols, it is suitable for integration in utility substation or industrial SCADA systems. Its powerful LED 7-segment display shines visibly in the darkest environments, facilitating a quick reading of crucial power parameters on-site. Likewise, it is equipped with a LED load-bar, enabling the viewing of load percentage at a glance.

The PM172 offers capabilities for basic power quality monitoring, providing calculations such as harmonics, THD, TDD and K-factor.Its powerful LED 7-segment display shines visibly in the darkest environments, facilitating the quick reading of crucial power parameters on-site. Likewise, it is equipped with a color LED load-bar, enabling the viewing of load percentage at a glance.
