Noneya - Indeed on everything...
Just want to point out why the current is reduced on overload...
This is because the current is detected on the primary side in that type of supply, which makes it actually a power limit protection and not a current limit protection. The voltage at the line doesn't change, and so while it does detect current to do the overload sense, this defines a maximum power input, and by increasing the voltage at the output, the trip point for the current must then be at a lower point to maintain sanity with Ohm's law.
Every switching power supply that uses input side current sense is affected by this.
