The D4i dimmable built-in constant current outdoor LED driver delivers precise and reliable performance for a wide range of industrial, road, and street lighting applications. It offers a dimming range of 1 to 100 percent, with a minimum current of 10 mA, allowing for highly flexible lighting control. The driver supports luminaires of both protection class I and protection class II and incorporates temperature protection in accordance with EN 61347-2-13 C5e standards. The output current can be adjusted between 200 and 1,050 mA using near field communication (NFC), DALI, or the ready2mains Programmer. With a maximum output power of 200 W and efficiency reaching up to 93.5 percent, it maintains exceptionally low standby power consumption of less than 0.3 W, minimizing energy use during idle periods.
This LED driver is equipped with multiple interfaces to provide comprehensive control and configuration options. Near field communication enables in-field programming, while powered DALI-2 and ready2mains allow configuration directly via the mains supply. The U6Me2 interface supports the programming of the programmable chronoSTEP function, controlling time schedules and dimming levels. Terminal connections utilize 45° push terminals for secure and reliable wiring. Additionally, the driver includes deviceKEY protection to prevent unauthorized changes to parameters and supports DiiA/Zhaga connectivity extensions DT49, DT50, DT51, and DT52, offering compatibility with a wide range of connected lighting systems.
Functionality extends beyond standard control, with adjustable output current in 1-mA steps, programmable chronoSTEP for customized time and level settings, and an enhanced constant light output function (eCLO) to maintain consistent light levels. The driver includes comprehensive protective measures such as overtemperature, short-circuit, overload, no-load, input voltage range monitoring, and reduced surge amplification. Intelligent Temperature Guard (ITG) and Intelligent Voltage Guard Plus (IVG+) provide additional safeguards, and configurable external temperature management (ETM) enhances operational safety. An auxiliary 24 V, 3 W power supply supports connected devices and sensors, making the driver highly adaptable for complex lighting networks.
The driver offers significant benefits for installers and system integrators, including flexible configuration through companionSUITE via NFC, DALI, or ready2mains, or through the U6Me2 programmer. Its wide application-oriented operating window ensures compatibility with various luminaire designs, while low standby losses combined with high efficiency contribute to optimal energy performance. In-field programming allows adjustments after installation without additional tools, and the driver provides robust protection against overvoltage up to 10 kV asymmetric for both protection classes, as well as integrated ESD protection for sensitive electronic components.
Electrical specifications include a rated supply voltage of 220–240 V, AC voltage range of 198–264 V, and DC voltage range of 176–280 V, supporting mains frequencies of 0, 50, and 60 Hz. Overvoltage protection can withstand 320 V AC for 48 hours, while inrush current peaks reach 85 A for 215 µs. Typical rated current at full load is 953 mA, with leakage current below 0.5 mA. The driver achieves a power factor of 0.98, total harmonic distortion under 8 percent, and maximum output voltage up to 400 V. Switching times are rapid, with AC mode starting under 0.75 s, DC mode under 0.8 s, and turn-off times below 0.5 s. The output current tolerance is ±3 percent, with peak currents limited to 15 percent above the nominal output, and low-frequency current ripple maintained within ±3.3 percent.
The robust construction of this D4i LED driver includes a polycarbonate casing and IP20 protection rating, with compact dimensions of 170 mm in length, 100 mm in width, and 40 mm in height. It is rated for a lifetime of up to 100,000 hours and comes with an 8-year manufacturer guarantee, making it a highly reliable solution for demanding outdoor lighting applications in roads, streets, and industrial environments.
