New miniature programmable DC power supply - FNIRSI DPS-150
Aldo22:
Has anyone tried out how quickly it regulates the current when you plug the cables in?
I have a lab power supply which regulates too slowly.
For example, if I set it to 100mA max, then remove the cables and plug it back in, I get a peak of about 700mA for half a second until it regulates again.
This means that a DMM with a 250mA fuse then needs a new fuse. ;)
What about the DPO-150?
You can test this with a DMM, which has a “Max” setting, or with an oscilloscope and a resistor.
Thank you.

Hello DaneLaw,
in your picture with the power bank the display of the DPS-150 shows 28V. Is the DPS-150 connected via barrel connector? According to this thread the max. voltage via PD is 20V, isn't it. :)

Yes, IM running it with PD3.1 chipped cable with a barrel connector rated for the wattage.. It will take its rated 32v voltage on both its TypeC or its Barrel connector.
The DPS150 internal PD-chip can only trigger up to (20v/5A) but you can easily trigger for it, outside, and it will just take it as a crude DC input without any handshaking.
Its inner barrel connector is the 2.5mm variant.
25v/5A

The graphing timebase segment' can be toggled between 1sec to 5sec.
and you can of course also use LIPO packs.
Like a 6cell that will be up around 24.5 to 25v when fully charged' just make sure to use cables that are rated for that amount of wattage.
Im not here, -with that amount of voltage sack.

Some of the features in the PC software that are just an executable. (don't need to be installed)
The start button up left, will start logging data values to an excel file..

I got one of these today.
The accuracy is amazing for a PSU.
Also ideal as an “afterburner” for those rather crude, cheap Aliexpress PSUs if you need a bit more control.
Still a cheap solution. Together with the 300W Longwei (which I had bought before), I paid less than $100.
