This fixed output LED driver is a reliable solution for self-contained emergency lighting, providing mains operation for LED modules with a forward voltage range of 50–220 V. Designed for direct luminaire installation, the driver features a low-profile cross-section of 21 x 30 mm and delivers output power between 6 and 75 W. The device operates in constant current mode with adjustable output current from 100 to 400 mA, configurable via ready2mains Programmer or I-SELECT 2 plugs. The integrated emergency lighting unit supports one-hour or three-hour rated durations and automatically shuts down the output if the connected LED load falls outside the specified range. A green LED indicates the battery charge status, while the electronic charge system manages battery health and safety.
Battery management includes polarity reversal protection, deep discharge protection, and short-circuit-proof battery connections to ensure safe and reliable operation. The driver is compatible with high-temperature NiCd or NiMH cells, including D, Cs, or LAL battery types. The electronic charging system maintains battery readiness while ensuring minimal energy loss during standby operation. Battery charging time is under 24 hours for full capacity.
Electrical specifications include a rated supply voltage of 220–240 V AC with a frequency of 50/60 Hz, an AC voltage tolerance of 198–264 V, and overvoltage protection up to 320 V for 48 hours. Typical rated current at full load is 380 mA, with no-load input currents of 16–18 mA depending on the emergency duration configuration. Leakage current at full load is below 0.25 mA, and inrush current peaks at 26 A for 280 µs. Maximum input power is 85 W, while typical no-load input power ranges from 2 W to 2.4 W. The driver maintains a high power factor of 0.98 and total harmonic distortion below 10% under full load conditions.
The device provides rapid response times, including standby start time under 0.25 seconds, mains-off start time under 1.3 seconds, and emergency detection start time under 0.5 seconds. Turn-off time under full load is below 0.05 seconds. Output current tolerance is within 5%, and low-frequency current ripple is below 5% at less than 120 Hz. Maximum output voltage, including open- or short-circuit conditions, reaches 280 V. The driver complies with EN 60598-2-22 for mains voltage changeover thresholds and withstands surge voltages of 1 kV between line and neutral, 2 kV between line/neutral and PE, and 2 kV at the output against PE.
Operating conditions accommodate ambient temperatures from –5 °C to 50 °C, with a maximum casing temperature of 75 °C. The device is rated IP20 for protection against solid foreign objects and limited access, and its operational lifetime extends up to 50,000 hours. This fixed output emergency LED driver is backed by a five-year guarantee, combining long-term reliability, precise current control, and robust battery and electrical protection for self-contained emergency lighting applications in commercial, office, and public building environments.
