Applications
Product types
Efficiency and cost optimization
- Primary-side regulation (PSR): these drivers eliminate the need for an optocoupler and secondary-side feedback, drastically cutting costs and PCB space.
- High power quality:engineered for professional and industrial lighting, they provide a high-power factor (>0.9) and very low Total Harmonic Distortion (THD) over a wide input voltage range.
- Integrated safety:advanced suite of protections, including overvoltage, overtemperature, and short-circuit, to ensure the long lifetime of LED modules.
The digital evolution for smart lighting
- SMED technology: powered by state machine event driven (SMED) engines, these controllers offer hardware-speed reaction times with the flexibility of digital programming.
- Precise dimming: capable of managing multiple PWM channels with ultra-high resolution (up to 1.3ns), ideal for sophisticated dimming and color mixing.
- Programmability: perfect for smart city applications and professional luminaires that require communication and custom lighting profiles.
Benefits
- Cost optimization: PSR technology reduces total system cost and complexity.
- Superior light quality: Accurate current regulation prevents flicker and ensures
- Smart & connected: STLUX enables the transition to digital, programmable smart lighting.
- Global compliance: Designed to comply with international standards for efficiency and harmonic distortion.
