3phase ATS Automatic Transfer Switch

GEYA GPS8 Series Automatic Transfer Switch (ATS) is a high-performance dual power controller designed to guarantee power continuity for critical loads. Combining rapid switching capabilities with advanced digital protection, this device monitors voltage and current in real-time, automatically transferring the load to a backup power source (such as a generator, inverter, or secondary grid) when the main power fails or becomes unstable. Ideal for residential, commercial, and industrial applications, the GPS8 ensures your equipment remains safe and operational.

Smart Auto-Manual Dual Mode & Microcontroller Precision Automatic Switching: Instantly detects grid failures (L1) and switches to backup power (L2) within seconds using advanced microcontroller tech. Manual Control: Override automation anytime to manually select L1/L2 power sources via intuitive interface

Fully Adjustable Triple-Layer Protection Pre-Set & Customizable: Factory settings suit most applications, while adjustable thresholds let you fine-tune overvoltage (OV), undervoltage (UV), and overcurrent (OC) protection for specialized needs. Grid/Generator/Inverter Safeguard: Shields sensitive equipment from surges, drops, and overloads across all power sources
