Soft-start function gradually ramps the output voltage to prevent abrupt surges that could damage a fan motor or LED lamp, extending their life. Digital voltage regulation provides precise, convenient control through a digital interface, allowing easy adjustment of fan speed or LED brightness. Time-based shutdown timer enables automatic power-off, supporting energy efficiency and a quiet environment. Power consumption reduction: a quick double-click turns off the digital tube display, minimizing energy use and reducing light pollution. Use cases: - PC case or electronics cabinet: use the soft-start to protect small DC fans, adjust speed with digital regulation, and turn off the display when silent operation is desired. - Desk lamp or LED lighting setup: fine-tune brightness with the digital control and set a timer to automatically power down after use. - Bedroom or media area: enjoy gentle startup for airflow or lighting, and use the display-off function to keep the room dark while maintaining control.
