SELF SLD45-1150IBD-UN 45W DALI-2 Dimmable Constant Current LED Driver

Compact DALI-2 and DIP-Switch Adjustable LED Driver for Professional Track Lighting

The SELF SLD45-1150IBD-UN is a compact 45W constant-current LED driver designed for efficient and flexible indoor lighting applications. Featuring DALI-2 digital dimming and a circular housing, it is particularly suited to built-in installation within LED track lights, spotlights and other compact luminaires used in retail, hospitality, office and commercial environments.

Operating from a 120–240V AC input, the driver offers 16 DIP-switch selectable output currents from 400mA to 1150mA in 50mA increments. Its regulated output voltage ranges from 6–42V DC, depending on the selected current, with a maximum output power of 45W at 220–240V AC. A full-load efficiency of 88%, low output ripple and power factor correction support dependable lighting performance.

The SLD45-1150IBD-UN supports DALI-2 dimming from 1–100%, with linear and exponential dimming characteristics for flexible brightness control. Its integrated DIP switch allows installers to configure the appropriate operating current for compatible LED modules. Built-in open-circuit, short-circuit and overload protection help safeguard the driver, with automatic restart after applicable electrical faults are corrected.

Designed specifically for built-in luminaire installation, the driver features Class II construction, SELV output and IP20 protection. Its compact black housing measures 75.5mm in diameter and 30mm in height, making it suitable for space-restricted fittings. With a nominal lifetime of 50,000 hours under specified operating conditions and a 5-year manufacturer warranty, it provides a practical solution for professional DALI-controlled LED lighting installations.
