Dual DPS5005 Lab Power Supply by slave2anubis

Last crawled date: 3 years, 1 month ago

This is a dual DPS5005, 5A, ~20V, bench power supply.
I built it using two DPS5005 with serial connection boards and a laptop PSU rated at ~20V and 6A.
The whole idea was to create a adjustable power supply with some kind of logging capability in a small form factor to be used in my electronics lab.
The design can be justed to fit other bigger PSU's inside, or adding two PSU's for two separate channels.
As for the heat, i left it more then 12 hour's with a 100W load attached and had no problems, due to the intake holes and the large 70mm fan all the power electronics stay cool.
