Power & Revenue 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.

Remote Power Meter

Transducer version (no display) of the PM172E

The RPM075 is a non-display power meter providing a solution for cases where there is no available space for display panels. Can be connected anywhere, via panel/wall and DIN rail mounting.



Remote Display

The RPM072 can be interfaced with Remote Display RDM172 via an RS485 communication port, or added as a second display for the PM172 series.
