## 45/60 Watts 

## • AC Input LED Driver **xxx Series** 

## • AC Input LED Driver 

- Constant Voltage/Constant Current Operation 

- Constant Current Dimming Versions 

- High Efficiency 

- Water Proof to IP67 

- Class 2 

- 3 Year Warranty 

The DLE series of AC input LED drivers incorporate universal input with active power factor correction in a two power stage design, eliminating flicker while providing a high efficiency solution. Designed as a class II isolation product, without the need for a safety earth, DLE series LED drivers are also approved as a class 2 limited power source, making them suitable for a wide range of applications. Dimmable constant current versions are available with the facility for PWM, voltage and resistance programming.
