I purchased the same power supply. By a current limiter do you mean Amperage? The PS is capable of putting out 120 watts, which at 12v would be about 10 Amps. I have the inbound power on mine going through a 10AMP fuse - from a car battery - don't know the amp hours of the battery.
The problem that I have is the PS works fine at 12.8 vdc (from a regulated supply) but in the vehicle at 13.73 vdc (battery charging) the PS shuts down. Figured that the inbound voltage should be 12v to 15v but maybe not.
