ZYG-GVD2280A Manuals

Zhuoyi ZYG-GVD2280A Full Isolation AC Solid-State Voltage Regulator User Manual

The ZYG‑GVD2280A is a full‑isolation AC solid‑state voltage regulator that integrates a synchronous transformer, phase‑detection circuit, phase‑shift trigger circuit and a TRIAC. By varying the control voltage (or current), the trigger angle of the TRIAC is adjusted, allowing precise AC voltage regulation for applications such as electric furnace heating, temperature‑controlled equipment, remote‑control systems, industrial automation, signal lights, stage lighting, instrumentation, and medical devices.

The manual describes the module’s structure, wiring connections, performance parameters, mounting dimensions, and safety precautions. It also gives detailed guidance on heat‑sink selection, installation, and protection measures such as external fuses or varistors to prevent over‑current and over‑voltage damage. This manual is written in Chinese.
