LED power supply for linear and area office luminaires
The Tridonic LC 20W 80–500mA 54V D4i NF h16 PRE4 is a premium LED power supply designed for modern linear and panel office luminaires. Its wide operating window lets you set the output current anywhere between 80 and 500 mA, so a single unit can match many LED module configurations and simplify project design and stock management. Constant current operation guarantees stable LED performance, while low current ripple and a high power factor support excellent light quality and energy efficiency in professional installations.
LED power supply with DALI‑2, DSI, switchDIM and NFC
This LED power supply offers extensive lighting control options. The DALI‑2 DT6 and DSI interfaces allow seamless integration into building automation and advanced lighting control systems. The integrated switchDIM function enables simple control via a standard mains pushbutton – a short press switches the power supply on or off, while holding the button smoothly dims the light up or down. With corridorFUNCTION you can easily create presence‑based lighting in corridors and circulation areas, using different light levels and delay times. Built‑in NFC communication makes configuration fast and flexible: output current, dimming limits, CLO curve and many other parameters can be programmed wirelessly using Tridonic companionSUITE tools.
Energy-efficient and durable LED power supply for demanding projects
With typical efficiency up to 86% and stand‑by power consumption below 0.2 W, this LED power supply helps reduce operating costs in commercial and office buildings. The Constant Light Output (CLO) feature compensates LED lumen depreciation over time, ensuring stable illumination levels and consistent visual comfort. The low‑profile 16 mm metal housing with IP20 rating fits easily into slim luminaires and ceiling systems, while robust protection functions (over‑temperature, short‑circuit, overload, no‑load and overvoltage) provide reliable operation in everyday use. A lifetime of up to 100,000 hours and a 5‑year manufacturer warranty make the Tridonic LC 20W 80–500mA 54V D4i NF h16 PRE4 a secure long‑term choice for professional lighting designers and installers, including projects with central battery and emergency lighting according to EN 50172.
