Description
The GDWY-30KVA is a high-power, industrial-grade three-phase automatic AC voltage stabilizer designed to compensate grid voltage fluctuations and deliver stable 380V AC output for critical loads. Adopting servo motor-driven carbon brush regulation + compensation transformer technology, it provides ±2% high precision and fast response under severe voltage swings (±20% input) and dynamic load changes.
Built into a heavy-duty steel cabinet with intelligent control system, LCD digital display and comprehensive protection circuits, it ensures 24/7 continuous operation in harsh industrial and substation environments. Widely used for production lines, CNC machines, laboratory equipment, substations and data centers where stable voltage is critical.
