Tridonic LED Dali Driver LCA 45W 500-1400mA one4all SR PRE - 28000672

You are viewing a brand new OEM Tridonic LCA 45W 500–1400mA one4all SR PRE LED Driver – Article No. 28000672

Step up to higher output with the Tridonic LCA 45W 500-1400mA one4all SR PRE, a premium-series independent dimmable constant current LED driver designed for luminaire installation with a strain-relief cable entry. Like the rest of Tridonic's PREMIUM range, it pairs strong power delivery with flexible, multi-protocol dimming control — ideal for linear and area lighting in office and commercial applications.

Adjustable output for higher-power fixtures

This driver's output current can be set anywhere between 500 mA and 1,400 mA, with a maximum output power of 45 W, making it a good fit for fixtures that need more power than the standard 25 W drivers in the range. Current can be configured via the ready2mains programmer, I-Select 2 plug-in resistors, or directly through DALI, giving installers a choice of set-up methods.

Efficiency runs up to 90%, and standby power consumption stays below 0.15 W, keeping running costs and wasted energy to a minimum.

Multi-protocol dimming built in

The one4all interface supports DALI/DALI-2, DSI, switchDIM, and corridorFUNCTION dimming, alongside ready2mains configuration and dimming via the mains supply. Dimming range covers the full 1–100% window, so one driver can serve multiple control set-ups without needing separate SKUs for each protocol.

Durable and protected

Housed in a white polycarbonate casing rated IP20, this driver includes overload, short circuit, overtemperature, and open/no-load circuit protection, plus reduced surge current on start-up. It's also suitable for safety and emergency escape lighting systems compliant with EN 50172.

Rated for up to 100,000 hours of service life and backed by Tridonic's 5-year manufacturer guarantee, it's built for long-term, low-maintenance use.
