An auto transformer starter (ATS) panel is an electrical control panel that uses an autotransformer to reduce the voltage supplied to a motor during startup, thereby limiting the inrush current. This method ensures smoother and more efficient motor starting, particularly for high-power motors, and is widely used in industrial and commercial settings.
