This document introduces the technical data, features, and functions of the AMDG-X/F series motor protectors. The product has multiple protection functions, including grounding, short circuit, phase loss, locked rotor, current imbalance, overload, overvoltage, and undervoltage. It also offers different relay contacts and communication interface options. Detailed user manuals and selection guides can be downloaded from the company's website.
The XINWEI AMDG‑X/F series motor protector provides comprehensive protection for three‑phase AC motors, including ground, short‑circuit, phase‑loss, stall, current‑imbalance, overload, and optional zero‑sequence, under‑load, over‑voltage and under‑voltage functions. The device uses a DSP core, offers digital parameter setting, LED display of currents, voltage and fault codes, and supports various communication interfaces.
The manual details technical data, relay types, physical dimensions, wiring connections, and step‑by‑step procedures for configuring protection parameters, interpreting fault codes, and performing resets. It also lists the optional features for each sub‑series (F0‑F8) and provides contact information for further documentation downloads. This manual is written in Chinese.

It protects against ground, short‑circuit, phase‑loss, stall, current imbalance and overload conditions.
Depending on the sub‑series, options include no interface, 4‑20 mA output, MODBUS/RS‑485, and PROFIBUS.
Zero‑sequence protection is optional and requires an external LJ‑type zero‑sequence current transformer.
