This constant current in-track LED driver is designed for luminaires requiring precise, reliable power control within a one-phase system. It includes an ACU ALU NIPPLE M10x1 accessory for mounting the luminaire head, which is supplied separately and not pre-assembled. Compatible with a range of in-track systems (refer to data sheet chapter 3.8), this driver supports luminaires of protection class II and incorporates temperature protection according to EN 61347-2-13 C5e. The output current can be selected via a DIP switch, offering fixed values of 900, 950, 1,000, and 1,050 mA, with a pre-selected current of 900 mA. The driver delivers a maximum output power of 44.1 W with up to 88% efficiency and a nominal lifetime of up to 100,000 hours, making it a durable solution for long-term lighting applications.
The housing is constructed from polycarbonate and is available in black, white, or grey, with IP20 protection, ensuring safe use in standard indoor environments. The driver is equipped with overload, short-circuit, and no-load protection, safeguarding both the fixture and the electrical network. Its compact form factor, measuring 140.6 mm in length, 36.6 mm in width, and 59.8 mm in height, allows seamless integration into in-track luminaires, particularly for spotlight applications in retail and hospitality settings.
Electrical performance is optimized for AC supply voltages between 198 and 264 V at 50/60 Hz, with overvoltage protection up to 320 V AC for two hours. The typical rated current at full load is 225 mA, with typical power consumption of 48.8 W and a minimum output power of 27.0 W. The driver maintains a high power factor, with λ ranging from 0.97 to 0.98 over the full operating range, and a total harmonic distortion (THD) of less than 10%. It features fast starting and turn-off times of less than 0.5 seconds and zero hold-on time during power failure. Output current tolerance is ±7.5%, with a maximum non-repetitive peak current of 1,176 mA and low-frequency current ripple under 5%.
Safety and reliability are further enhanced with surge protection capabilities of 1 kV between line and neutral, 2 kV between line/neutral and PE, and surge voltage at the output side below 3 kV. The driver is rated for an ambient operating temperature of 25 °C for full lifetime performance, with storage temperatures ranging from -25 to 80 °C. Its maximum output voltage is 59 V, making it suitable for a variety of LED modules. This in-track LED driver combines precise current control, robust protection features, and long-term reliability, making it an ideal solution for focused, high-quality spotlight applications in commercial and hospitality lighting. It comes with a 5-year guarantee for added assurance.
