Hi newbie here be gentle, Got a 32-36v psu with 1400ma regulated current also bought a 50w 32-36v led 1700ma max. Now these are sold as a stand alone working pair, what it the simplest way to get the led dimming, I am about to buy an Arduino as its a project for a reef lighting system. We need to get a rtc and a touch screen controller for the arduino as well.
Could i use the pwm feed from the arduino to feed a tc1427 then 2 mosfets IRL13705N Slight overkill as the mosfets are rated at 52amp 55v but comes on an arduino board
The build will be 6 x 50w leds ran of one dimming channel then 10 royal blues ran of another pwm channel and finally violet leds running from a third pwm channel
At first i was going to have a common psu supplying a 30amp 36v pwm speed control but the constant current drivers for the leds would have been far to much so the cheapest way is one psu per led
Thank you
