I just purchased myself a small bench power supply for low current and low voltage applications, mainly for digital designs, to use at 3.3v and 5v. As I browsed the selections on CPC Farnell website I did the usual scope creep in specification and price before winding back down to a nice little Duratool unit, the D03232 https://cpc.farnell.com/duratool/d03232/power-supply-1ch-15v-2a-adjustable/dp/IN07999

Duratool D03232 power supply

The unit is extremely lightweight and compact and sits well on my shelf, which is only 260mm deep. So there is still some shelf space for other electronics

 

The specification is 15v / 2A although no-load the output is 15.7v....I've yet to experiment with max. loads so will update when I've used it for a bit longer.

 

The only concern, and something I should have checked, is that there is no output on/off. The only switch controls the mains power and so you may not know what the last setting was and burn out a new circuit. When turning on the output also momentarily displays a high voltage ( 166v last time) although I haven't seen that when looking with a scope.

 

I'll probably try and make an output switch that sits directly in the 4mm posts - I have a friend with a 3D printer and hopefully he would be willing to make a nice compact enclosure for it. Unless anyone has any other recommendations or seen something available already?

 

For higher power loads at 5v and 12v I still use a modified ATX power supply unit.

 

Overall, I'm very pleased with the size, specification and price.
