* Maximum Load: 1-4 Luxeon LEDs, no less than 1Watt each.
* Total num of load= Input voltage /4, for example:
minimum input volatge @ 280mA
* Preset Current: 285mA, may vary from 240mA - 310mA
* Current Ripple: 4mA RMS, 26mA p-p
* Maximum Input Voltage: 24V
* Suggested Input Voltage: 7-15V DC
* Efficiency:73% @12V input, 3*1W Luxeon LEDs in series connection
Suggested connection is shown in Figure 2.
