Multi-function Power Meter
The PM135 is a multifunctional three-phase power meter.
Featuring versatile I/O options, communication ports and protocols, it is ideal for integration in utility substations or industrial SCADA systems.
An LCD display, accompanied by a LED load-bar, enables easy on-site access to power parameters and viewing of load percentage at a glance.
