Product Description
PM3000 Power Master is a compact power monitoring and control platform built for small to medium electrical monitoring projects. It combines power meter data collection, supervisory display, alarm and event recording, historical trend, power quality monitoring, demand control and automatic reporting in one system.
It is suitable where a full SCADA system is too complex, but the site still needs power monitoring, electricity reports, demand control, e-mail alerts, remote web access and integration with third-party supervisory systems.
Corrected model name: Based on the datasheet, the product is PM3000 Power Master, not PA3000.
