I have this constant voltage aquarium light that I found can be divided into 3 channels relatively easy.
Also know that the TC-420 controller will PWM dim LED strip lights. I'm trying to bring the 2 together.
Problem is the MOSFET output of the TC-420 is on the neg side. The light has a negative bus and each channel is on the pos. side..
So I thought the below could basically reverse this condition using a p channel MOSFET as a second pulse width switch.
Important parameters:
15V constant voltage power supply
TC-420 is said to work between 12-24V but I believe some have run it w/ lower input voltage.
TC-430 will not have a "load" to control really..It will just be a PWM output generator..
Current will be in the new MOSFETS.
Anyways the point is to change the neg pulses to positive pulses
Now this may be COMPLETELY wrong but I'd appreciate any feedback on this, EVEN if to say I'm an idiot..
Anyways a diagram:
