LED drivers can be dimmed by analogue, PWM or resistor

RECOM expands its portfolio of dimmable LED drivers with the 25W RACD25-A and 35W RACD35-A. Both feature 3-in-1 dimming, allowing the modules to be dimmed with an analogue signal (1-10V), PWM or external resistor. Each is available in 1 of 5 different types of output current, ranging from 350 to 2100mA, making them capable of powering a wide range of CoB LEDs.

Each unit offers an excellent power factor (over 0.98 at 120VAC, over 0.93 at 240VAC and over 0.9 at 277VAC) and efficiencies of 81% for the RACD25-A and 83% for the RACD35-A. Both modules are just slightly larger than a deck of cards (102x73.5x33mm), so are easily integrated into almost any application.

With a wide input voltage range of 90-305VAC, these versatile drivers are suited for worldwide power grids. Target applications include general lighting, public buildings, retail, outdoor lighting, architectural lighting and bathrooms.

The units carry double-isolated wires, are housed in IP67-rated casing and protect against short circuit, overload and over-temperature. The drivers are environmentally versatile, suitable for both indoor and outdoor use, in damp and wet areas.

The RACD25-A and RACD35-A LED drivers are UL8750 and EN61347 certified, comply with the European harmonics standard EN61000-3-2 Class B and come with a five year warranty.
