Power Supply for High Power LED String

Hi guys,

 

Sometime ago I asked about how to power a led cluster or another, and decided to make changes to the design. Now I would need to power High Power Leds on 4 different PCBs. About 200mA 40V per PCB is needed. I am also planning to use STCS1A chips and a microcontroller to control the PWM signals that I'll feed to the chips.

 

I believe I would need a constant output of 40V/3A. Could anyone offer any input on the best power supply that I would need for this?

 

Thanks a lot!
