The QY series thyristor regulators from Yinhe High‑tech Development are designed for precise power control in industrial heating, motor drive and transformer regulation applications. The manual provides a complete guide to product features, wiring, control methods and safety precautions.
Key sections include product introduction, model designations, technical specifications, wiring diagrams, control signal input methods, output characteristic curves, and after‑sales service information. The document also lists optional functions such as over‑voltage, over‑heat, soft‑start and soft‑stop protection. This manual is written in Chinese.
| Input Voltage | Three‑phase AC 380 V ±15 % or single‑phase AC 220 V ±15 % |
|---|---|
| Control Power Range | 10 kW – 500 kW (customizable) |
| Control Signal (Voltage) | DC 0–10 V or DC 0–5 V |
| Control Signal (Current) | 4–20 mA |
| Overheat Protection Temperature | 70 °C |
They are used for temperature control in industrial furnaces, glass production, diamond press heating, torque motor speed control, rectifier transformer regulation, and other high‑power heating and control fields.
The regulator uses phase‑shift (移相) triggering to provide stepless voltage regulation, allowing continuous adjustment of the output voltage.
The devices include over‑voltage protection, over‑heat protection, soft‑start and soft‑stop functions, and can be configured for constant‑voltage, constant‑current or over‑current protection as needed.
