The MWH-10 meter provides high precision measurement, display and remote communication functions for active watt-hour and active power. It can also be equipped with 2 relay outputs, 2 external control inputs and 1 RS485 communication output (Modbus RTU Mode) or 1 pulse output interface, making it suitable for a variety of applications such as power management, remote input and output, alarm and remote communication control.
The ADTEK MWH-10 is a digital energy meter that provides high‑accuracy measurement of active energy (Wh) and active power (W). It features dual‑window display, optional RS485 Modbus RTU communication, pulse output, and two configurable relay outputs for remote monitoring and control.
The manual describes product features, wiring diagrams, configuration options, timer function, error messages, and safety specifications, enabling users to install the meter in shallow‑depth DIN panels and integrate it into energy management or building automation systems. This manual is written in Chinese.
