The LED driver has a dual mode of operation:CV mode: at loads below the preset current limit, the RACD60 behaves as a fixed voltage source. CC mode: at loads above the preset current limit, the RACD60 behaves as a fixed current source. Thus the same power supply can be used with both CV and CC LED modules. The RACD60 series have a universal input voltage range with active power factor correction and are fully protected against output short circuit, overload and over-temperature. Three versions are available: a low cost openframe with either internal (/OF) or external useradjustable current limit (/TOF), and a sealed IP67 potted version (/IP67) with factory set output currents for outdoor or high humidity applications.

This may damage the LED or sharply reduce its life. RACD60 /TOF Output Current Adjustment Normalised Output current (%) 1.0 The /TOF offers the possibility to derate the output current with an external voltage or PWM signal. Thermal feedback derating is an effective way to reduce the LED current at high temperatures to avoid over-stressing the LED.

If only two or three strings are wired in parallel then it is recommended to add resistors (e.g. 0.5R) to each string to help balance out the LED currents in each string. All strings must share a common heatsink for better current matching. Last LED 1st LED String 1 Last LED 1st LED String 2 RACD60 Last LED 1st LED String n A typical 1W high brightness white LED has a forward voltage of around 3.3V at its operating temperature and draws 350mA. Thus each LED actually draws about 1.15W. Similarly, 3W white LEDs have usually the same forward voltage but can be run at 700mA or more. Using the LED datasheet specification, the optimum LED arrangement and the best driver for each application can be worked out. The tables below show some examples. Other LED combinations may have different forward voltages at their recommended operating currents. 1W LEDS 24 26 28 30 33 35 35 36 39 42 42 42 45 LED Arrangement 2 Strings of 12 2 Strings of 13 4 Strings of 7 3 Strings of 10 3 Strings of 11 5 Strings of 7 7 Strings of 5 3 Strings of 12 3 Strings of 13 3 Strings of 14 7 Strings of 6 14 Strings of 3 3 Strings of 15 www.recom-international.com AC/DC Driver RACD60-700 RACD60-700 RACD60-1400 RACD60-1050 RACD60-1050 RACD60-2100 RACD60-2400 RACD60-1050 RACD60-1050 RACD60-1050 RACD60-2400 RACD60-4200 RACD60-1050 3W LEDS 12 14 18 18 LED Arrangement 12 in series 2 Strings of 7 3 Strings of 6 6 Strings of 3 AC/DC Driver RACD60-700 RACD60-1400 RACD60-2100 RACD60-4200 High Power LEDs LED Arrangement AC/DC Driver Cree CXA2011 Cree XM-L Lumiled Rebel Single Array 6 in series 13 in series RACD60-1050 RACD60-2100 RACD60-700 Osram Dragon 14 in series RACD60-1050 Bridgelux RS Single Array RACD60-2100 Helieon Single Module RACD60-1400 REV:4/2011 29
