DIN rail mount programmable power supply

[Dr_Neoo]

Hello all,

I'm trying to find if there any of the shelf DIN mount/small formfactor progamable power supplies. 0-30 V and 1A would be ideal but down to 0V is not a hard requirement. Control could be anything from analog input to USB as long as it can be automated.

So far I have mostly found stuff like NI Pixi modules or larger standalone lab power supplies. There is also a module from beckhoff that looks interesting but it is not released yet: https://www.beckhoff.com/en-en/products/i-o/ethercat-terminals/el9xxx-system/el9501.html

I could design a custom solution but I thought that checking here for suggestions first would be a good idea ( don't need more new projects... 😉)

This clip should expand the field of possibilities.

I think that will cost you serious cash. Its a bit niche.

 You may want to (reluctantly) use a separate USB DAC and use the output to program a simpler analog programmed PSU module. This kind of thing https://www.lucid-control.com/product/lucidcontrol-ao4-4-channel-analog-output-usb-module/ I'm sure there are chaeper versions. Or possibly use an RS232 prog'd psu with a https://www.secomp-international.com/en_US/roline-usb-2-0-to-rs232-adapter-for-din-rail-1-port/i/12.02.1001-4 or similar

how about opendps as the software and this as the hw:

amazon.com/dp/B09B1NW9NH

(dps5005 series).

I have some small boxes that are 3d printable that fit this.  you could adapt that for din rail use.

its fanless and it just takes a dc input (wall wart).  and yes, its remote controllable (I'm working on a fork that expands a bit on the opendps firmware).

if you get the module that has both serial interfaces (bt and usb) then you can pick what you want.  use an hc05 since I think the bt interface is classic and not ble (else, use an hm10 or similar for the pc side).

there is a cli util for linux (source) that will get/set values via simple .c program.

(I'm actually going to be updating my github with this info shortly)

I have used these psu's for a few years now and they are quite nice for the price and remote control ability.  and being fanless helps, too.

main github site:

https://github.com/kanflo/opendps

the author has not updated things in a while and seems to have given the project all he intends (which was a huge amount!)

I'm adding some more features, myself, but just some minor updates.

go to that main site, first, to see what its about.
