This is an old revision of the document!
This article is about measuring the accuracy on the EA PS 2084-03 B power supply.

Until then I used and ATX power supply with an ATX breakout board. I provides all voltages needed for electronics: 3.3 V, 5 V, and 12 V. But you can't set the current. It only comes with a 1.25 A polyfuse.
So I decided it was time to buy my first bench power supply. But is had to fulfil the following criteria:
- set voltage and current
- wide voltage range (0-50 V)
- silent
- have an earth connection
- not expensive
- not noname
- provide a communication interface (most important)
I found and bought a used power supply on eBay for ~ 80 €. And now I own an Elektro-Automatik EA-PS 2084-03 B power supply. And this fulfilled are the requirements:
- set voltage and current: in 0.1 V and 0.01 A steps
- wide voltage range (0-50 V): 0-84 V, 0-3 A (not a lot, but enough for electronics), limited to 100 W
- silent: not fan, full passive cooling
- have an earth connection: on the front panel
- not expensive: ~ 80 €
- not noname: Elektro-Automatik (never heard of it, but it's German and they have a decent website)
- provide a communication interface: USB with proprietary documented protocol
Here some more documents about this power supply:
- driver (USB ACM for Windows)
- easyPS2000 software (Windows, demo only)
