racd60 www.recom-international.com 29 rev:4/2011 lightline ac/dc-converter racd60 series application information leds are typically wired in series to make a string of leds and then the strings can be wired in parallel to generate enough li ght. 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. -(#

# - # # 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. usi ng 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 f orward voltages at their recommended operating currents. 1w leds led arrangement ac/dc driver 24 2 strings of 12 racd60-700 26 2 strings of 13 racd60-700 28 4 strings of 7 racd60-1400 30 3 strings of 10 RACD60-1050 33 3 strings of 11 RACD60-1050 35 5 strings of 7 racd60-2100 35 7 strings of 5 racd60-2400 36 3 strings of 12 RACD60-1050 39 3 strings of 13 RACD60-1050 42 3 strings of 14 RACD60-1050 42 7 strings of 6 racd60-2400 42 14 strings of 3 racd60-4200 45 3 strings of 15 RACD60-1050 3w leds led arrangement ac/dc driver 12 12 in series racd60-700 14 2 strings of 7 racd60-1400 18 3 strings of 6 racd60-2100 18 6 strings of 3 racd60-4200 high power leds led arrangement ac/dc driver cree cxa2011 single array RACD60-1050 cree xm-l 6 in series racd60-2100 lumiled rebel 13 in series racd60-700 osram dragon 14 in series RACD60-1050 bridgelux rs single array racd60-2100 helieon single module racd60-1400 derating graphs " " " "
