ZYG-GVD2280A is a full isolation AC solid-state regulator module that integrates a synchronous transformer, phase detection circuit, phase shifting trigger circuit and output thyristor. By changing the control voltage (current) size, the output thyristor trigger phase angle is changed to achieve AC voltage regulation. This product can be widely used in electric furnace heating constant temperature equipment, remote control systems, industrial automation control devices, signal lights, stage lighting control devices, instruments, medical devices, etc. In some special devices requiring shock resistance, corrosion resistance, moisture resistance, and explosion protection, this product has incomparable advantages over traditional regulators in harsh working environments.
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.
