I use this as a lipo charger and as multimeter ans as power supply. Pro: The unit is very quiet. The fan only runs when the heatsink is getting warm. With no/limited load it wont run at all. The PSU withstands a shortcut on the output for 2 hours @ 15 Amps. The hottest parts inside were about 47degree (IR-camera measured). The accuracy is good! Voltage: <= 0.02V@>10V and <=0.04V@<10V on the input terminals, <= 0.01@>12V and <=0.02@<12V on the output terminals the measurement of current is less accurate, and less stable. Especially at lower CC. But still very good. (<0.02A) Accuracy is difficult to measure, because the current is not too stable at lower CC settings. This little unit is a nice to have PSU on the workbench, and if you feed it with some old laptop-adapters in series, you have a silent, reliable and high-current PSU! Disadvantage: The description mentioned that you can charge batteries with it. That is not a good idea, since the unit also drains power from the output terminals if there is no input power available. So smaller batteries will be drained pretty soon. The DPS5015 uses 35mA@12V. (Graph horizontal: Voltage from a Korad PSU, vertical: measured difference between the Korad and the compared devices like the DPS5015)
Tested with a lab power supply, 30V input, 10V, 5A out on an active load (that are the limits of my test set not of the power supply). Efficiency 97.5%, ripple 10mV peak to peak. All the internal parts really cold. The menu is very useful and ergonomic with a lot of interesting functions. What else?
