DPS3005 - Digital Power Supply from Banggood

Описание: DPS5003 and DPS3005 are (adjustable) Digital Power Supply available on Banggood. First one can work up to 50V/5 A, and second one 32V/5 A. Another version, not mentioned (author not aware of that) is DPS 3003, with available current up to only 3 A. Also other versions for higher current, or with lower voltage/current accuracy are not mentioned because it is out of scope of this video. At the time I am buying this supply, 50V one is sold out, so I bought 32 V version. Input voltage can go up to 40 volts, but output voltage is always at least 1.1 V less than input, or 32 V maximum for DPS3005 or 50V for DPS5005. Note that this device is just controller unit - no transformer, no rectifier and/or capacitors. Use your own transformer with rectifier, or another unregulated PSU as input PSU. Minimum input voltage is 6V, below which it refuse to output any voltage. At say 5 V input, it can just show display, but can't output proper result - and it refuses to output anything. Reason is that control device inside require stable voltage of 5 V, and in order to get it - input voltage should be at least 1.1 V above that value. On this video, I am using old computer PSU, which gives me 11.5 V (this is old and probably broken unit). Forgot to mention bottom row on the display - showing input voltage, but I bet you are already figured it out.
