This combined emergency LED driver is a versatile solution for self-contained emergency lighting systems, supporting manual testing for rapid verification of functionality. The driver can be installed either as a built-in module or independently using the optional clip-on strain-relief accessory, providing flexible installation options for various luminaire types. With a maximum output power of 32 W and a nominal lifetime of up to 100,000 hours, it is suitable for long-term operation in offices, retail, healthcare, and public building applications. The driver delivers constant power output in emergency mode and is fully compliant with EN 50172 standards for emergency escape lighting systems.
The device supports adjustable output current between 350 and 700 mA via I-SELECT 2 plugs, allowing precise control over LED module operation. It includes comprehensive protective features, such as overtemperature, short-circuit, overload, no-load, and input voltage range protections, ensuring safety and reliability under all operating conditions. The driver supports emergency operation durations of one or three hours, depending on the connected battery, and maintains output stability even under peak load conditions.
Battery management is handled through an intelligent charge system, providing deep discharge protection, polarity reversal safeguards, and short-circuit-proof battery connections. The driver is compatible with NiCd or NiMH batteries, which offer a design life of four years, ensuring extended reliability and minimal maintenance requirements.
Electrical specifications include a rated supply voltage of 220–240 V AC with a frequency of 50/60 Hz and overvoltage protection up to 320 V for 48 hours. Typical rated current during full-load charging is 178 mA, with no-load input current of 20 mA. The driver exhibits a peak inrush current of 4 A for 260 µs and a maximum input power of 38.8 W, with typical no-load input power of 1.1 W. Efficiency at full load is 84% with a power factor of 0.95, and total harmonic distortion is 14%.
The starting time under full load is less than 0.5 seconds, with AC to emergency switchover occurring in under 0.5 seconds and turn-off time under full load under 0.05 seconds. Output current tolerance is less than 5%, with non-repetitive peak output exceeding 35% and low-frequency current ripple below 5%. Maximum output voltage, including open- or short-circuit conditions, is 60 V, and the mains voltage changeover threshold follows EN 60598-2-22 standards. Surge capability reaches 1.2 kV between line and neutral, 2.4 kV between line/neutral and PE, and 2.4 kV at the output against PE.
Ambient temperature ranges vary with output power: for outputs ≤25 W, –25 °C to 50 °C or 40 °C depending on conditions; for outputs >25 W, –25 °C to 45 °C or 35 °C. Maximum casing temperature is 80 °C. The driver has a long operational lifetime of up to 100,000 hours and is backed by a five-year guarantee. This combination of adjustable output, robust protective features, intelligent battery management, and flexible installation makes the driver ideal for emergency lighting applications in commercial and public spaces.
