LED power supply Tridonic LCA 50W 100–400mA one4all lp PRE – technical data

LED power supply for demanding office and commercial projects

The Tridonic LCA 50W 100–400mA one4all lp PRE is a high-end LED power supply designed for modern linear and panel luminaires in offices, corridors and public buildings. The wide adjustable output current range from 100 to 400 mA allows precise matching to many LED modules used in recessed panels, linear systems and downlights. With up to 50 W output power, this power supply is suitable for both compact single luminaires and larger modular systems.

The slim, low-profile metal housing with only 21 mm height makes installation easy even in very shallow ceiling systems and narrow profiles. Designed as a built-in component with IP20 protection, the power supply fits perfectly into indoor luminaires. Support for luminaire protection classes I and II offers maximum flexibility to luminaire manufacturers and system integrators.

Power supply with DALI-2, ready2mains and advanced control

This LED power supply is equipped with the one4all interface supporting DALI-2 DT6, DSI, switchDIM and corridorFUNCTION. It can be seamlessly integrated into building management systems, lighting control networks and presence-based control scenarios. With ready2mains, configuration and dimming signals are transmitted via the mains wiring, eliminating the need for separate control cables in many projects.

The 1–100% dimming range is implemented by amplitude dimming, providing flicker-free light and high visual comfort in offices, meeting rooms and environments with computer workstations. Additional functions such as Constant Light Output (CLO), fade2zero soft switch-off and power-up fading at start-up enhance comfort and extend system lifetime. With lumDATA support according to DALI-2 parts 251, 252 and 253, the power supply can store luminaire data, provide energy reporting and support diagnostics and maintenance.

Efficient, reliable LED driver for long-life installations

Efficiency up to 92% combined with stand-by consumption below 0.17 W helps to reduce operating costs in energy-efficient office buildings and public facilities. The integrated Intelligent Voltage Guard system continuously monitors under- and overvoltage on the mains, improving protection of the power supply and connected LED modules.

The Tridonic LCA 50W 100–400mA one4all lp PRE offers a rated lifetime up to 100,000 hours and a 5-year manufacturer’s guarantee, making it a reliable choice for professional lighting projects. Compliance with key standards such as EN 61347, EN 62384, EN 62386 (DALI-2) and suitability for emergency lighting systems according to EN 50172 and EN 60598-2-22 ensures safe use in certified luminaires. For OEMs and installers looking for a flexible, configurable and durable LED power supply, this model provides an optimal balance of performance, control features and energy efficiency.
