Hi there, I ve bought recently my very first power supply 30v 5A. Please anyone can tell me if it’s a normal behaviour that the OCP alarm start when I set current output under 0.089A. It just happen when I set current output from 0.001 to 0.089A.

From the owners manual:

From that description the buzzer should only sound if there is a short or the load is trying to draw more current then the supply was set at.
From your description of the issue it appears there may be a minimum CC setting for the alarm although no mention in the manual I could find.
It's possible there is a defect.
I guess the only way to know is for someone with the same supply to post a reply as you mentioned.
