Multi-function Power Meter
The PM172 is a Class 0.2S/0.2 power meter designed for high-accuracy metering of three-phase AC circuits.
Equipped with built-in digital I/Os and supporting numerous communication protocols, it is suitable for integration in utility substations or industrial SCADA systems.
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.
