Suitable for constant current LED luminaires, the RACD45-A and RACD60-A series have been annonuced by RECOM Lighting. The 45 and 60W LED drivers feature a 3-in-1 dimming function which enables the drivers to be controlled with 1-10V analog, PWM, or external resistor dimming.

Opeating from input volatges of 90-305V AC, the RACD45-A series has four models offering current output ranges of 700-1850mA, and the RACD60-A series has five models with current output ranges of 1050-4200mA. The LED drivers are supplied with IP67-rated enclosures (protected against ingress of dust and moisture), enabling the drivers to be installed in industrial or out-buildings as well as damp rooms like bathrooms or basements.

Operating over a temperature range from -30 to +65°C, the class 2 power supplies feature an excellent power factor of greater than 0.98 at 120V AC, greater than 0.93 at 240V AC and greater than 0.9 at 277V AC. Additionally, the RACD45-A and RACD60-A series provide efficiencies of more than 87% and low THD. The modules are fully protected against short circuit, overvoltage, and over temperature.

Steve Roberts, Technical Director, RECOM, commented: “With the flexible dimming options we are able to offer customers the usage of standard dimmers as well as to tailor the output current by using a simple resistor which could be placed at the light engine.”

The RACD45-A series has dimensions of 171.1x45.3x32.5mm and the RACD60-A series has dimensions of 174x45x30mm. Complying with the European harmonics standard EN61000-3-2 Class C, the UL8750 and EN61347 certified LED drivers are supplied with a five year warranty.
