easy to take apart, just unclips (no screws)mosfet is N308ADyou can find some reviews of similar items on YT (inline led pwm dimmer)this works on about 730 - 750 Hzmax duty cycle is around 90% (with 2 led strips; with one it was only about 76%)i doubt those wires will take 6A, and probably you'd need a heatsink on the mosfet as well when driving hardthe pot has a switch tooI'm using it to drive 2 led strips as wide screen backlight, the dimming is going to come handy
