This dimmable IP20 built-in constant current LED driver sets the industry benchmark by combining long lifetime, high surge immunity, high power factor, and high efficiency with extensive programmability and integrated power features. Fully DALI-2 and D4i certified, the driver includes dual integrated power supplies to support the ZD4i ecosystem, offering both bus power and a 24 V DC auxiliary power supply for sensors and control devices. Integrated power monitoring and energy reporting allow standalone luminaires to meet adaptive lighting requirements, while streetlights and interconnected systems can leverage smart lighting functionalities. Suitable for luminaires of protection class I and II, the driver also provides additional equipotential connections to offer more flexibility in design. Programming can be performed wirelessly via NFC or DALI, while selected features can be configured through cabinet programming using u6Me2. The driver supports a nominal lifetime of up to 100,000 hours, ensuring long-term reliability.
The driver offers versatile interfaces including NFC for programming and configuration, DALI-2 and D4i (powered DALI-2) for intelligent dimming and communication, and cabinet programming via u6Me2 to set chronoSTEP times and levels through mains power. Terminal blocks with 45° push terminals simplify installation and connection. Its functions include an integrated bus power supply to operate sensors and control devices in compliance with DALI part 250, and an integrated 24 V, 3 W auxiliary power supply (DALI part 150) for devices requiring higher power. The driver supports data reporting in accordance with DALI parts 251, 252, and 253, covering luminaire, energy, and diagnostics data. Autonomous dimming via the chronoSTEP function can be programmed using NFC, DALI, or u6Me2, and the constant light output (CLO) function ensures consistent performance. A full protection suite safeguards the driver against overtemperature, short-circuit, overload, no-load, undervoltage, overvoltage, and reduced surge amplification. Additionally, deviceKEY prevents unauthorized parameter changes.
The benefits of this driver include its future-proof functionality, combining chronoSTEP, DALI-2, and D4i dimming capabilities in a single device. Robust thermal behavior simplifies design integration, while sensors and communication devices can be powered directly by the driver, reducing system complexity. Flexible configuration is available via companionSUITE software or cabinet programming, and a wide operating window supports various LED module combinations. In-field reprogramming via NFC and u6Me2 allows updates after installation, and the driver enables energy metering and predictive maintenance. High overvoltage protection up to 10 kV asymmetric accommodates protection class I and II applications, and integrated ESD protection ensures operational stability. Typical applications include road and street lighting, tunnels, residential areas, and industrial or area lighting projects.
Electrical specifications include a rated supply voltage of 220–240 V with an AC voltage range of 198–264 V and a mains frequency of 50/60 Hz. The driver supports overvoltage protection up to 320 V AC for 48 hours. Typical rated current at full load is 355 mA, with leakage current below 0.7 mA and touch current of 600 µA when equipotential connected. In-rush current reaches 42.6 A with a duration of 162 µs. Maximum input power is 80.5 W, while standby power consumption is under 0.45 W. Output power ranges from 8 to 75 W with efficiency at full load of 93 percent. Power factor (λ) ranges from 0.65 C to 0.98 over the full operating range, and total harmonic distortion (THD) remains below 7 percent. AC mode start time is under 0.7 seconds, turn-off time under full load is below 0.03 seconds, and output current tolerance is ±3 percent, with maximum non-repetitive output peak current of 805 mA. The output LF current ripple is ±5 percent, P_ST_LM at full load is ≤1, and SVM at full load is ≤0.4. The maximum output voltage is 180 V, with a dimming range from 10 to 100 percent. Mains surge capability reaches 6 kV between L-N and 10 kV between L/N-PE, with burst protection up to 4 kV and output side surge under 1 kV. The driver measures 133 mm in length, 77 mm in width, and 31 mm in height, holds an IP20 protection rating, and comes with a 5-year guarantee.
