This dimmable built-in constant current LED driver is engineered for professional-grade performance and versatility, suitable for luminaires of protection class I and II. It provides reliable and flexible current control with selectable fixed output currents of 200, 250, 300, 350, 400, 450, 500, and 550 mA, with a pre-selected default of 200 mA. The output current can be conveniently adjusted either via DIP switch or through DALI commands, allowing precise customization down to 1 mA increments. With a maximum output power of 75 W and a rated efficiency of up to 93%, this driver ensures high energy conversion and minimal losses in demanding lighting applications. It also incorporates temperature protection compliant with EN 61347-2-13 C5e standards, extending operational reliability and safeguarding against overheating.
Designed for long-term durability, the driver achieves a nominal lifetime of up to 100,000 hours and carries a 5-year guarantee. Its low-profile metal housing with a white cover ensures ease of integration into compact luminaire designs while maintaining a clean, professional appearance. The unit provides IP20 protection, making it ideal for indoor environments where ingress protection against solid objects is sufficient. Engineered with an anti-glowing design, it prevents unwanted residual light emission when turned off, maintaining lighting quality and user comfort.
Equipped with versatile one4all interfaces, including DALI-2, switchDIM, and corridorFUNCTION, the driver supports multiple dimming and control protocols for adaptive lighting management. Its 0° push terminal blocks enable quick and secure wiring connections, further simplifying installation. Functionally, the driver supports constant light output (CLO) operation to maintain consistent illumination levels over time, as well as protective mechanisms against overtemperature, short-circuit, overload, and no-load conditions. It is also suitable for use in emergency escape lighting systems in accordance with EN 50172, ensuring dependable operation in safety-critical environments.
Configuration flexibility is enhanced through companionSUITE software, which allows intuitive setup and parameter adjustments via DALI. The application-oriented operating window supports a wide range of LED modules, maximizing compatibility across linear and area lighting applications. In addition to its strong performance metrics, the driver achieves excellent energy efficiency through low standby losses—under 0.45 W—helping reduce operational costs and energy consumption.
Operating across a broad input range of 198–264 V AC or 176–280 V DC, the driver supports both alternating and direct current modes, with mains frequency compatibility from 0 to 60 Hz. It withstands overvoltage conditions up to 320 V AC for 48 hours and provides robust protection against transient electrical disturbances, including 1 kV surge protection between line and neutral and 2 kV between line/neutral and protective earth. On the output side, it offers surge immunity below 3 kV against PE.
Electrical performance is optimized for professional use, with a typical rated input current of 360 mA at 230 V and a power factor (λ) reaching up to 0.97 under full load. Total harmonic distortion (THD) remains below 8%, ensuring stable and efficient operation. The driver’s start-up times are rapid—under 0.7 seconds in both AC and DC modes—with a switchover time of less than 0.3 seconds between power sources. The turn-off response is also nearly instantaneous, under 0.05 seconds. Output parameters are tightly controlled, maintaining a current tolerance of ±5% and a low-frequency ripple below ±3%, while flicker performance meets high-quality lighting standards with PstLM ≤ 1 and SVM ≤ 0.4.
Supporting a dimming range from 1% to 100% (with a minimum current of 5 mA), this driver ensures smooth, flicker-free light transitions ideal for applications requiring fine control over brightness levels. The maximum output voltage reaches 250 V, with a rated output power window from 11.5 W to 75 W, accommodating a wide variety of LED load configurations. The unit’s in-rush current peaks at 30.5 A for 163.9 microseconds, demonstrating robust electrical tolerance during startup.
Compact and installation-friendly, the driver measures 280 mm in length, 30 mm in width, and 21 mm in height, making it suitable for integration into slim linear fixtures or shallow housing designs. Its construction and performance characteristics make it particularly suited for linear and area lighting systems across retail, commercial, and industrial applications where reliability, flexibility, and precise dimming control are essential. Combining high efficiency, broad compatibility, and extended service life, this driver represents a dependable solution for modern lighting environments requiring intelligent control and lasting performance.
