PC-class dual power automatic transfer switch

NEW QUALITY UPGRADE & MORE DURABLE
This 4P PC-class dual power automatic transfer switch (ATS) is engineered for low-voltage power distribution. It automatically switches loads between main and backup power sources upon detecting power failure or voltage abnormality, maintaining uninterrupted power supply for critical loads. It features both automatic and manual operation modes, with a lockable rotary handle to avoid unauthorized operation. The built-in LCD screen and status indicators provide real-time working data and clear state feedback. With high-strength conductive parts and reliable mechanical interlock structure, it prevents simultaneous connection of two power sources. It is widely applied in commercial buildings, hospitals and industrial projects to guarantee safe and stable power switching.
