On your last board above, the Design Rules Check Off the top you likely want high current screw terminals connected directly to the Mosfet source and drain with large wide traces and a much better drive circuit than is currently present. I’d suggest a drawing showing how this fits together, this board with the leds (with their current draw specified) connected where you expect and the driver that drives this board so we can make better suggestions. The mosfet gate is being driven from an optocoupler from a high resistance voltage divider which isn’t low enough (as it will give about 18V on the gate which is speced at 16V max with the swithing threshold at 2.5V so way to much voltage no where near enough current for good drive. 1 connectors (which are speced at 3A max but I would say even 1 A is likely pushing it). You say “high power” but the 36V power to the Mosfets are going through multiple. I expect more information is required to give a good answer here, but I already see a number of problems. ![]()
