[PSUBS-MAILIST] Constant current LED driver

[Alan James via Personal_Submersibles]

Perhaps I could go with this motor driver, & set the voltage down to 36V.Jtron PWM DC Motor Speed Controller - Green (15A / 6~90V)

 I like this from DX. Find the cool gadgets at a incredibly low price with worldwide free shipping here.  |   |

Then use this constant current driver (75W max)Constant Voltage Constant Current DC-DC Power Module for Arduino

 I could have 2 constant current modules running off the motor speed controller,so a total of $16:22 to run two 50W LEDs.   What I am not sure of is whether the input capacitors on the constant currentdrivers would be killed eventually by the PWM (16KHz). Or whether I can wire a differentcapacitor between the two units to avoid this.Are you listening in Ken?Cheers Alan

Alan, this link says that they have the driver in stock.

 it will do what I want, but is a bit big & expensive. One option is to buy a couple of these &just use the voltage step down function & run a number of smaller constant current drivers off it.For anyone running 36V, there are a heap of cheap constant current drivers & LEDs in thatrange to make up cheap & powerful lights.Alan
