This manual introduces the product features and usage of EA05AF automatic voltage regulator.
This manual provides technical parameters, wiring diagrams, and installation precautions for the EA05AF automatic voltage regulator used with self-excited generators. It details input voltage requirements, power consumption, excitation field output, and adjustment procedures.
Operational guidance includes startup steps, low‑frequency protection adjustment, voltage and stability tuning, as well as a troubleshooting table for common issues such as voltage not establishing or unstable output. This manual is written in Chinese.

The regulator accepts an input voltage of 160 V to 260 V AC, single‑phase two‑wire.
Check that the residual magnetism voltage (SVAC) is above the required level; if it is low, apply a short external DC source (3‑12 V) to the excitation leads to re‑magnetize, then restart the generator.
