1–10V Rotary Dimmers
Take full control of your lighting.
Designed for use with high-frequency ballasts or LED drivers that accept a 1–10V DC control input, these rotary dimmers put smooth, responsive dimming right at your fingertips. Turn the knob to set the perfect brightness. Push to switch the mains power on or off. Clean, simple, intuitive control — every time.
Thanks to electrical isolation between dimming and switching, performance stays consistent and reliable. A single dimmer can operate one or multiple ballasts or drivers, making it a flexible choice for both small setups and larger lighting installations.
Just check your ballast or driver data sheet to ensure the combined control current doesn’t exceed 20mA, and keep the total mains load within 6A. For higher inrush currents, we recommend fitting inrush current limiters or using an additional high-current switch for mains control.
Wiring made simple:
This dimmer requires an additional two-core cable, as switching and dimming are handled separately. Wire the mains side as you would a standard switch, then connect the dimming side to the + and – terminals on your dimmable ballast or LED driver. Full wiring diagram included.
Bring precision dimming to your project — and make lighting control effortless.
