Get flexible, reliable dimming control with the Tridonic LCA 25W 350-1050mA one4all SR PRE, a premium-series constant current LED driver built for professional lighting installations. Part of Tridonic's trusted PREMIUM range, this compact driver combines high efficiency with genuine multi-protocol dimming versatility, making it a smart choice for offices, linear lighting, and area lighting applications.

Adjustable output to suit your fixture

Unlike fixed-output drivers, this unit lets you set the output current anywhere between 350 mA and 1,050 mA, giving you the freedom to fine-tune brightness to match your luminaire design. Adjustment can be made via the ready2mains programmer, I-Select 2 plug-in resistors, or directly through DALI, so you can configure it the way that suits your workflow best.

With a maximum output power of 25 W and efficiency up to 90%, this driver delivers strong performance while keeping running costs down. Standby power draw is under 0.1 W, helping minimise wasted energy when the fixture isn't in use.

Multi-protocol dimming built in

The "one4all" interface is what sets this driver apart — it supports DALI DT6, DSI, switchDIM, and corridorFUNCTION dimming, plus ready2mains configuration and dimming straight through the mains supply. That means a single driver can cover multiple control set-ups, cutting down on the need to stock several driver variants. Dimming range runs smoothly from 1% to 100%.

Built to last, built to protect

This driver is fitted with comprehensive protection circuitry, guarding against overtemperature, short circuit, overload, no-load/open circuit conditions, and input voltage fluctuations, with reduced surge current for gentler start-up. It's also suitable for use in emergency escape lighting systems compliant with EN 50172, making it a versatile option where standard and emergency lighting needs overlap.

Backed by a rated service life of up to 100,000 hours and Tridonic's 5-year manufacturer guarantee, this is a driver designed for long-term, low-maintenance operation.
