The DC LED driver is a dimmable independent constant current solution specifically designed for 24V input applications, providing precise control and robust performance for a wide range of low-voltage systems. This driver features adjustable output current between 100 and 550 mA and supports a maximum output power of 20 W. It achieves up to 91.5% efficiency while maintaining minimal power input on stand-by of less than 0.35 W. The dimming range spans from 2 to 100%, with a minimum dimmable current of 10 mA, making it ideal for luminaires of protection class III. Its design supports both solar-powered systems and other 24V battery applications, enabling extended autonomy and integration with modern energy management solutions.
The driver incorporates multiple interfaces for flexible connectivity, including near field communication (NFC), powered DALI-2, and a zhaga book 18-compliant socket for sensor integration. These interfaces allow seamless interaction with DALI-2 sensors, communication nodes, and compatible auxiliary devices. Key functions include adjustable output current in 1-mA steps through NFC or DALI, enhanced constant light output (eCLO), and protective features such as overtemperature, short-circuit, overload, no-load, and input voltage range monitoring. The driver also supports DALI-2 compliance for firmware updates, auxiliary power supply, integrated bus power supply, luminaire data, energy reporting, and diagnostics and maintenance, providing comprehensive functionality for modern lighting and off-grid systems.
Intelligent safeguards, including Intelligent Temperature Guard (ITG) and deviceKEY protection against unauthorized parameter changes, enhance reliability and safety in demanding applications. The driver delivers a 24V, 3W power supply and supports DiiA/Zhaga connectivity extensions DT49, DT50, DT51, and DT52, enabling advanced integration for connected lighting systems. Configuration flexibility is provided via companionSUITE for NFC and DALI, allowing in-field programming even after installation. Its low standby losses contribute to extended battery life and prevent deep discharge, making it particularly suitable for solar street lights, off-grid systems, boats, camping equipment, and traffic signage.
In terms of electrical performance, the driver exhibits an in-rush current of 77.3 A with a duration of 235 µs, an output power range from 1.8 to 20 W, and starting times of 0.5 s in stand-by and 0.85 s in DC mode. Turn-off time at full load is 0.05 s. Output current tolerance is ±3%, with a maximum non-repetitive output peak of 15% above the nominal current. Low-frequency output current ripple remains within ±3.3%, while the maximum output voltage reaches 100 V. Housed in a robust casing with IP67 protection, the driver measures 162.5 mm in length, 73 mm in width, and 43 mm in height, offering durability and environmental resistance for outdoor and wet applications. With a nominal lifetime of up to 50,000 hours and an 8-year guarantee, this DC driver combines long-term reliability, flexibility, and efficiency for a wide range of 24V low-voltage installations.
