New miniature programmable DC power supply - FNIRSI DPS-150

I just wanted to mention that I am very satisfied with this little device.
The volts and amps can be adjusted with sufficient precision and safety.
I use it more often than I would have thought because it just sits there without taking up any space.  :)
Meanwhile, my 300W Longwei is in the cupboard.

I feed it with a 45W PD fast charger. That's enough for almost everything for me.
I can recommend it.  :-+

I hope EEVblog will test this device!
In general, how reliable is FNIRSI with fixing and updating the firmware for this model?

Does anyone have tips on an older EU adapter for electronics that supports 230V input and can deliver over 30V and 5A, so I can get the full output of 30V and 5A?

This little device simply works. I haven't found any problems yet.
Therefore it does not need an FW update.  ;)
A Python script for remote control would be nice.

I took a look at the “problem” with the subsequent triggering of the overcurrent protection.

It's not ideal, but it's not that bad either.
It protects the first time. It shows you “OCP” in red when it has switched itself off.
Do not switch it on again in this state, but press “Home” twice.
Then “OK” appears again in green and so you can switch it back on and the protection works.
If you know this, it is not a problem imo. But yes, it could be done better.

Hello there!
Anyone knows if it has reverse current protection?
For example: I'd like charge EFB car battery with CC 5.0A / CV 14.60V until my power bank with PD@20V runs out of juice.
Will DPS-150 survive when power bank recovers and for some reason negotiate lower voltage, like 5V of 12V?
