Digital Panel Meter
A Digital Panel Meter (DPM) is a full‑fledged electronic measuring instrument that converts incoming electrical signals into readable digital outputs on LED or LCD screens.
It measures voltage, current, power, energy and other parameters, available in single‑function and multi‑function versions. Current transformers are required for AC measurements.
It requires auxiliary power supply, and supports RS485 communication, alarm and analog transmission. Common standard cut‑out sizes include 48×96 mm and 72×72 mm.
It features high‑precision intuitive digital display, flexible panel‑mount installation and wide signal compatibility with optional alarm and communication functions.
It is widely applied in industrial distribution cabinets, power supply equipment and automatic machinery for real‑time electrical parameter monitoring.
