TCI Low voltage 12-24V dimmer PWM for LED strip

The TCI Low Voltage 12-24V PWM Dimmer for LED strips is a compact and versatile light control device designed for recessed installation in Safety Extra Low Voltage (SELV) systems. Thanks to its 250 Hz PWM technology, it delivers smooth and precise dimming for LED strips powered at 12V (up to 55W) or 24V (up to 110W).

This TCI dimmer stands out for its operational flexibility, supporting three selectable control modes via dip-switch, making it suitable for professional and residential installations requiring reliable and accurate light management.

Main technical features

Light intensity regulation ranges from 0/0.5 to 100%, achieved through the PUSH LV function, a 0/1...10V interface (current 0.4 mA), or a 10 KΩ potentiometer. The dimming mode — between 1...10V control and Push function — is selected via the dip-switch located beneath the terminal cover. The PUSH function allows switching on and off with a short press and intensity adjustment with a longer press, with automatic stop at minimum and maximum values and dimming level memory upon power restore. The PVC body measures a compact 57 x 57 x 22 mm with a protection rating of IP20.

Safety and protection

The dimmer operates exclusively within protection class III, ensuring maximum safety in extra-low voltage systems. The maximum control cable length from push button to last driver is 15 metres; for longer runs, cables must be kept separate from the 100-240V mains. Only normally open push buttons without incorporated indicator lights must be used.

Applications

This TCI PWM dimmer is the ideal solution for LED strip dimming in residential, commercial and contract environments where precise light control is required with a minimal footprint and a clean recessed installation.
