The power supply was operating normally, then it went off in the middle of a test.
the switch was pressed ON, but the screen was off, it is checked from the back and the 2A fuse is burned, it is replaced by an equal one of 2A, but pressing the switch immediately burns the fuse.
Is it possible that a short in the terminals (+, -) could damage the equipment?
or is it due to some internal defect of the power supply?
