Technical data of Tridonic LED power supply LC 75W 250-400mA 220V o4a lp ADV

LED power supply for advanced linear and area luminaires

This Tridonic LED power supply LC 75W 250-400mA 220V o4a lp ADV is designed for professional luminaires. It is perfect for linear fixtures, panels and general area lighting. Constant current operation ensures stable performance of modern LED modules.

The output current is adjustable between 250 and 400 mA. Setting is done via the I-SELECT 2 interface using dedicated plugs or resistors. Fine 1 mA steps give lighting designers precise control over module loading and system efficiency.

High typical efficiency above 92% reduces power losses and heat generation. This helps to extend the lifetime of the whole luminaire. Low stand-by consumption below 0.4 W supports energy efficient building concepts.

LED power supply with DALI-2, DSI and switchDIM control

The power supply integrates multiple control options in one compact device. It supports digital DALI-2 DT6 and DSI protocols. Additionally it offers switchDIM control for direct connection of a pushbutton.

With switchDIM you can switch and dim the luminaire without a complex control system. A short press toggles ON or OFF. Holding the button dims up or down. All units in one group can be synchronized to 50% with a dedicated press sequence.

The integrated corridorFUNCTION V2 enables simple corridor lighting logic. It provides background level and presence dependent control. This is ideal for staircases, corridors and technical areas where safety and savings matter.

Safe, reliable LED power supply for long term use

The low profile ML300 housing allows installation in slim linear luminaires. IP20 rating makes it suitable for integration inside indoor fittings or ceilings. Push terminals simplify wiring and reduce assembly time in production.

The power supply includes a full set of protection features. It is protected against overheating, short-circuit, overload, no-load operation and mains surges. In case of a fault the output is deactivated and can be restarted after correction.

Designed lifetime up to 100,000 hours and a five year manufacturer warranty ensure long term reliability. Compliance with emergency lighting standards allows use in central battery systems. This Tridonic LED power supply is an excellent choice for offices, schools, healthcare and commercial projects.
