Dimmable IP20 built-in constant current 40 W DALI-2 LED Driver. Designed for basic, functional streetlighting and outdoor luminaires.
The SNC D4i intelligent driver enables interconnection with smart lighting systems, data collection and maintenance as well as simple integration of sensors and controllers into the luminaire through the dual integrated power-supply of the driver. The sensors and communication devices are directly powered from the driver and are therefore easy to integrate into the luminaire.
The drivers are based on industry standards with regards to programming, safety and energy efficiency (high surge/burst, NFC programming, high Power Factor, long lifetime). With the driver based chronoSTEP functionality, luminaires can be dimmed autonomously in the central hours of the night. One wide operating window to cover several operating points of the luminaire.
Functions
- Future proof driver with chronoSTEP, DALI-2 and D4i dimming capability combined in one device
- Dual integrated power supply for the ZD4i ecosystem – bus power supply and 24 V DC AUX power supply to power sensors and controls.
- Constant light output function (CLO)
- Intelligent Voltage Guard Plus (IVG+)
- Full protection set (overtemperature, short-circuit, overload, no-load, undervoltage / overvoltage, reduced surge amplification)
Interface
- Near field communication (NFC). Support for NFC multiple programming (single and multi packaging)
- In-field (re-)programming via NFC and u6Me2 possible after installation
- U6Me2 (configuration of chronoSTEP times and levels via mains)
- One adaptable chronoSTEP profile compromising 7 dimming steps offers needed functionality but less complexity
- Terminal blocks: 45° push terminals
Benefits
- High overvoltage protection: up to 10 kV asymmetric
- Nominal lifetime of 100,000 h and 5-year guarantee
- Smaller housing sizes of 133 mm length to fit into miniaturized luminaires
Typical applications
- For standalone luminaires to achieve adaptive lighting requirements or streetlights that are interconnected with smart lighting systems
- Road & street, tunnel, residential, area and industrial lighting
