# Am I interpreting power supply current limit function correctly?

A bench power supply has one variable and two fixed voltage outputs. Below are the related specs: I highlighted the 5V output specs to focus on it for simplicity of the question.

Regarding 5V fixed output the nominal output current is given as 1A. The limited current is given lets say 1.5A. It says it can be between 1.2 and 1.6 but lets say ours is 1.5A.

Now what I understand from these is: if I connect a 5 Ohm load across 5V output the current will be 1A.

If I vary the load to 3.333 ohm the load will see 5V and pass 1.5A.

But if I vary the load to 1 ohm the load will pass 1.5A but the voltage across the load will be 1.5V.

Are my above conclusions based on the specs correct?

(I’m trying to verify whether this supply has such functionality and whether I understand constant current compliance concept.)

It is hard to determine from the datasheet alone and may need testing to be sure.

I have seen supplies similar to this one do one of two things when reaching the limit:
