* use suffix /OF for open frame version (standard) - output current limit adjustable with on-board trimmer
* use suffix /TOF for open frame version with thermal feedback - output current limit externally adjustable.
* use suffix /IP67 for waterproof potted version - fixed output currents only
ordering examples:
RACD60-700/OF= open frame, adustable current limit preset to 700mA.
RACD60-1050/TOF=open frame,1050mA, adjustable 700-1050mA with ext. voltage or PWM signal.
RACD60-1400/IP67 = enclosed IP67 waterproof, non-adjustable 1400mA output.
Note: all currents within range are available - use RACD60-xxxx/IP67 where xxxx is the desired fixed current
e.g. RACD60-900/IP67 = enclosed IP67 waterproof, non-adjustable 900mA output.

RACD60
Description
The RACD60 is a compact universal input voltage
60W constant constant current power module
suitable for driving high power LEDs. 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, over-
load and over-temperature.
Three versions are available: a low cost open-
frame with either internal (/OF) or external user-
adjustable current limit (/TOF), and a sealed IP67
potted version (/IP67) with factory set output
currents for outdoor or high humidity applications.

/TOF Output Current Adjustment

Normalised Output current (%)
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.

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 light. 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. 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.
