Since the launch of the Lifud A1 series-an isolated, full-voltage range street light power supply-it has garnered widespread recognition and favor among overseas customers thanks to its high reliability, wide voltage compatibility, and robust protection capabilities. To further meet the diverse control requirements of smart street lighting, Lifud has launched the IP42-rated version of its A1 dimmable series, delivering a more flexible and intelligent power solution for outdoor lighting projects.

A Proven Legacy with Upgraded, Robust Quality

As the latest additions to the A1 series, both the IP67 and IP42 dimmable models inherit the series’ high-performance DNA:

• Wide Voltage Compatibility: An ultra-wide input range of 90–305Vac easily handles complex grid fluctuations.

• Highly Reliable Architecture: Features 3rd-generation SiC semiconductor technology and explosion-proof film capacitors, combined with a 50,000-hour full-power lifespan design to withstand harsh outdoor environments.

• Comprehensive Protection: Includes multiple safeguards against over-temperature, over-voltage, under-voltage, and short circuits, plus 10kV lightning protection, ensuring the stable operation of the lighting system.

• Global Certifications: Backed by ENEC, CE, CB, RCM, and SAA certifications, ensuring easy compliance with project standards worldwide.

Dimmable Capabilities for Flexible Smart Control

Supporting 3-in-1 dimming, scheduled dimming, and Constant Light Output (CLO) functions, Lifud LED drivers enable tiered brightness control and intelligent time-based adjustments based on road lighting needs. This effectively reduces energy consumption and extends luminaire lifespan, perfectly meeting the requirements for precision management in smart street lighting. Additionally, when paired with a Lifud programmer, parameters can be easily customized to meet specific project needs and ensure rapid configuration.

Dual Protection Options to Suit Various Luminaire Designs

The IP67 version simplifies waterproof design requirements for luminaires, eliminating concerns about thunderstorms or humid weather. The IP42 version allows for lower overall luminaire costs when paired with an effective waterproof fixture design. No matter your luminaire design, there is a Lifud LED driver that fits your needs perfectly.

Comprehensive power range coverage for worry-free selection

The A1 series offers options for both dimmable and standard ON/OFF models, covering a power range of 40W to 240W. Across the entire lineup, efficiency reaches up to 94%, with a power factor >0.9 and THD <10%-delivering high energy efficiency and grid-friendly performance while meeting the power requirements of mainstream street lighting applications.

Choose Lifud for your power supply needs

From non-dimmable to dimmable versions, and from IP42 to IP67 ratings, the Lifud A1 series has undergone continuous iteration and upgrades-all to provide customers with more comprehensive and perfectly tailored power supply solutions for outdoor lighting.
