Qlt RGBox 55 24V power supply 55W for LED RGB systems DMX

QLT RGBox 55 is a converter power supply for 24V RGB LED systems, designed and manufactured by QLT for professional colour light control in constant voltage installations. The compact PVC enclosure — measuring 147 x 75 x 39 mm — integrates all the electronics required to independently drive RGB LED strips and modules, delivering an output power of 55W across three PWM channels at 24V DC, each rated at 2A. The unit accepts standard mains input at 220–240V AC, with Insulation Class II and an IP20 protection rating confirming its suitability for protected indoor environments.

This power supply is engineered for technical installations where colour management is the central element of the lighting design: commercial staging, architectural feature lighting and high-end contract projects. The DMX input with built-in self-test function and signal LED enables seamless integration into professional automation and control systems. Alternatively, switching, dimming and colour regulation can be managed via one or more push-buttons, making the unit equally suited to applications where DMX control is not available. Parallel connection of up to 10 RGBox units via the included 1-metre cable allows straightforward system expansion, scaling the installation to meet requirements of different sizes and complexities.
