Features LED DRIVER ● ● ● ● ● ● ● ● LIGHTLINE AC-DC LED Power Supply 60W Dual Mode CV and CC Output Power Factor Corrected Universal Input Voltage Ranges Low Cost Open Frame Design High Efficiency Adjustable Current Limit Long 5 Year Warranty AC/DC-Converter with 5 year Warranty Description A compact universal input voltage 60W constant voltage/ constant current switching power module suitable for driving high power LEDs. The LED drivers have a dual mode of operation: CV mode: at loads below the preset current limit , the RACD60 behaves as a voltage source. CC mode: at loads above the preset current limit, the RACD60 behaves as a current source. Thus the same power supply can be used with both CV and CC LED modules. The current limit can be set by the user. The RACD 60 series have a universal input voltage range and are fully protected against output short circuit, overload and over-temperature. The converters feature built-in power factor correction as standard. 60 Watt PFC Single Output Selection Guide Part Number Input Voltage Range (VAC) Output Voltage (VDC) Output Current Preset Efficiency Max Adjust Range Current Limit (230VAC) Power (mA) (mA) (%) (W) RACD60-4200* universal 11 min - 13.5 max 3570 - 4200 4200 85 60W RACD60-2400* universal 17 min -24 max 1700 - 2500 2400 87 60W RACD60-2100* universal 21 min - 28 max 1400 - 2140 2100 89 60W RACD60-1400* universal 21 min - 28 max 1400 - 2140 1400 89 60W RACD60-1050* universal 33.5 min - 48 max 825 - 1250 1050 89 60W RACD60-700* universal 38 min - 54 max 700 - 850 700 89 46W RoHS 2002/95/EC 6/6 UL Pending EN 61347 Certified CE Marked * add suffix /OF for open frame version (Standard) or add suffix /IP67 for potted version Input Voltage Range 90-264VAC Rated Power 47-63 Hz Power Factor Correction Full Load, 115VAC/230VAC Input Current (full load) 115VAC/230VAC 0.8A / 0.4A max.

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 Power LEDs LED Arrangement AC/DC Driver Cree MX-6 Cree XP-G Lumiled Rebel 11 in series 3 in parallel 13 in series RACD60-1050 RACD60-2100 RACD60-700 Lumiled Star 3 strings of 4 RACD60-2100 Bridgelux ES 3 in series RACD60-1050 Helion Single Module RACD60-1400 REV:5/2010 27 RACD60 Series LIGHTLINE AC/DC-Converter Package Style and Pinning RACD60-xxxx/OF 3rd angle projection 101.6 FG FG CN1 CN2 3 4 5 2 1 45 50.8 Current Limit FG 95.3 Use M4 Mounting Screws 25.5 Pin Connections – Single Output 28.0 Pin # Function 1 VAC in (L) 2 VAC in (N) 3 NC 4 +VDC Out 5 -VDC Out Filter Ground connection via mounting holes Dimension Tolerance ± 0.25 mm RACD60 RACD60-xxxx/IP67 118 35 300mm Cable 300mm Cable 110 Pin Connections – Single Output Wire 121.5 Function Brown VAC in (L) Blue VAC in (N) Red +VDC Out Black -VDC Out Filter Ground connection via mounting holes Dimension Tolerance ± 0.25 mm 28 REV: 5/2010 www.recom-electronic.com
