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. Two versions are available: a low cost open frame with user-adjustable current limit and a sealed IP67 potted version with fixed output currents for outdoor and high humidity applications.

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 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.
