Features: This is a safety isolated standard 0-10V dimming controller that uses PWM digital brightness adjustment technology, allowing stepless brightness control via a manual knob. It is designed to control various LED dimmable drivers and dimming electronic ballasts that accept 0-10V dimming signals to adjust LED lamp brightness. The dimming range is 0-100%, and the safety isolation circuit helps protect the load from damage due to voltage fluctuations. Compatible with at least 95% of drivers using standard 0-10V dimming signals. Easy to install: The ultra-thin design allows for simple installation in electrical boxes and wall panels for convenient and intuitive operation.
