High Power Current Limiting Circuit. Therefore a high input voltage supply or current limit can cause very high power dissipation in the high side switch during current limiting. Im an ee minor and know a little about circuits but not enough to tackle this on my own.
The photo show i dimming a 3w led with a current limter. Connect the current limiter in series between the component that you wish to limit its current and the voltage source. At best shunt regulators like this have 60 75 efficiency so at 1200w out that little fet is.

One style of current limiting circuit is shown in the image. Im an ee minor and know a little about circuits but not enough to tackle this on my own. Potentiometer r5 was adjusted to set the current limit a little above 1 a. Check before apply some voltage.
