Hello there!
My power supply works fine until I forced it to the maximum levels... When I increase the voltage near to 280V and current is 4.9 A the power supply works at least 30 seconds and the voltage falls down until 250V, current to 3.5A, you can decrease but not increase the levels.
In addition, I check the current with a DMM and there´s a difference between my DMM and the front panel display.
Do you think this is a calibration problem?
best regards

Another possibility is that your output stage cannot handle the full load, which means the unit needs to be repaired.
