The QY series thyristor voltage regulator is designed for industrial furnace heating, glass production, diamond press heating, torque motor speed control, and various power‑transformer applications. It offers both single‑phase and three‑phase versions, with AC regulation and rectifier regulation functions, and integrates power, control, protection, and cooling circuits in a compact aluminum housing.
The manual includes product introductions, application fields, wiring diagrams, control signal input methods, output characteristics, safety precautions, and after‑sales service information. It also lists detailed model specifications, mechanical dimensions, and optional features such as over‑voltage, over‑heat, soft‑start and soft‑stop protections. This manual is written in Chinese.
