The LED emergency driver is a versatile and compact solution designed for self-contained emergency lighting systems. It functions as a dimmable built-in LED driver and includes an integrated emergency lighting unit with automatic self-test functionality. The unit is suitable for LED modules with a forward voltage range of 20 to 50 V and provides SELV-compliant output voltages below 60 V DC. Housed in a compact plastic casing, the driver combines durability with flexible installation options, making it ideal for modern indoor emergency lighting applications.
The driver delivers constant current operation with output currents ranging from 300 to 1,400 mA during mains operation. Adjustments in 25 mA increments can be made using the I-SELECT 2 PLUG, allowing precise adaptation to various LED modules. Emergency operation is supported for durations of one, two, or three hours, selectable via a simple two-way dip switch. The unit automatically shuts down output if the LED forward voltage falls outside the defined range, protecting the connected light modules. A two-color LED status indicator provides clear information on operational condition, while an electronic multi-level charge system ensures proper battery maintenance. Pulse current charging is supported for NiMH batteries, and the driver incorporates deep discharge protection, polarity reversal protection, and short-circuit-proof battery connections for enhanced safety and reliability.
The driver offers a broad range of interface options, including switchDIM, corridorFUNCTION, and Rest mode, enabling flexible control scenarios for different emergency lighting applications. Terminal connections are simplified through 45° push terminals. The unit accommodates high-temperature NiCd or NiMH batteries in various form factors, including D, Cs, LA, or LAL cells, and can be connected to a battery box for independent operation. All components are rated for a design life of four years, ensuring long-term reliability and minimal maintenance requirements.
Electrically, the driver operates on a supply voltage of 220–240 V at a frequency of 50 or 60 Hz, with overvoltage protection up to 320 V for 48 hours. Leakage current is kept below 0.5 mA, and the power factor (λ) under normal operation is 0.95, with a total harmonic distortion (THD) below 10%. Emergency operation starts in under 0.5 seconds following detection of a power failure, delivering an output current with a tolerance of ±7% and a low-frequency ripple of less than 2% below 120 Hz. The maximum open circuit voltage is 60 V, and the mains voltage changeover complies with EN 60598-2-22 standards. The driver operates within ambient temperatures from –5 to 50 °C for units up to 40 W and –5 to 45 °C for higher-power units, with a maximum casing temperature of 75 °C.
Physically, the driver is rated IP20 for indoor use and has a guaranteed operational lifetime of up to 50,000 hours. A five-year warranty reinforces its reliability and suitability for continuous emergency lighting applications in commercial, institutional, and public buildings. The combination of flexible interfaces, precise current control, integrated safety features, and compatibility with multiple battery types makes this LED emergency driver a robust and dependable solution for modern emergency lighting systems.
