The emergency lighting LED driver is a compact, low-profile solution for self-contained emergency lighting systems, offering reliable operation for LED modules with a forward voltage range of 50–250 V. With a cross-section of only 21 x 30 mm, the driver integrates seamlessly into luminaires while providing essential emergency functions. It operates in non-maintained mode and supports rated durations of one, two, or three hours, selectable through a plug-based duration link. The driver employs 3-pole technology, enabling two-pole LED module changeover and delayed power switching for the LED driver, ensuring stable performance and protection against overloading. Automatic shutdown of the output occurs if the LED load falls outside the specified range, while constant power output is maintained for consistent performance. A two-colour status display LED provides clear visual indication of operational status.
The driver incorporates a sophisticated electronic charge system, deep discharge protection, and short-circuit-proof battery connections, with polarity reversal protection implemented via the 3-pole connector. It automatically detects the type of connected battery technology, supporting both NiMH and LiFePO4 batteries, and accommodates various cell formats including LA and 18650. LiFePO4 batteries benefit from Tridonic LiFeGuard protection for extended reliability. Self-test capabilities include monitoring of battery status, LED status, functional testing, and duration verification, in accordance with IEC 62034 standards. Compatibility extends to most constant current LED drivers, allowing flexible integration across a range of luminaire designs.
The driver supports high-temperature battery cells and is compatible with both NiMH and LiFePO4 chemistries. LiFePO4 batteries with Tridonic LiFeGuard ensure safe operation and extended design life, while battery selection guidance is available in the respective data sheet. Electrical specifications include a rated supply voltage of 220–240 V, AC voltage range of 198–264 V, and mains frequency of 50/60 Hz. The output current follows the specifications of the connected LED modules, with a maximum open circuit voltage of 300 V. The driver provides surge protection of 1 kV between L-N and 2 kV between L/N-PE, with the same 300 V capability on the output side.
Designed for demanding environments, the driver operates reliably across ambient temperatures from -25 °C to 55 °C, with a maximum casing temperature of 80 °C, and is rated for IP20 protection. In rest mode, it supports up to 100 emergency units with a maximum wiring distance of 1,000 meters. Functional testing occurs weekly with a five-second test, while annual duration tests are configurable for one, two, or three hours depending on system requirements. The nominal lifetime of the driver reaches up to 100,000 hours, ensuring long-term reliability, and it comes with a five-year guarantee. This combination of compact design, flexible battery compatibility, comprehensive self-test functions, and robust protection features makes the driver ideal for professional emergency lighting installations.
