The power supply is excellent for its money. There is no loud noise in work, also at high output powers. Some minor buzz presents but is not disturbing. The voltage is calibrated well. The protection circuits function properly, although I did not test its speed and sensitivity. Unfortunately the control knobs are analog (potentiometers), hence the sensitivity of a current limit feels too high for a 60A unit. This also leads to practical lower limits of 20 mV and 20 mA. This is more than enough for most applications, but could be improved by digital controls (replacing the potentiometers with encoders) in the next version. If curious, my device does not have a PC interface.
Very good. Works well. I will give additional feedback later if it continues to work. Good salesman
