Cheap Cicso Power Supply
When searching for a cheap solution to power my JMC Colsed Loop Steppers i stumbled on a thread about using 2nd hand Cisco Switch Power supplies for RC-Charging. As i used old server-supplies for that purpose years ago, i thought i would give it a try. I ordered a Cisco WS-CAC-1300W from ebay for less than 20€ - you can normaly find them ~30€ if you search a bit.
They offer 27A @42V and additionally some amps at 12 and 5V for other stuff - perfect for a CNC Machine. If thats not enough, there is the same form-factor available with 3000W or 6000W - if needed.
The Quality of the power supply is like military grade - heavy as hell and a fan that would be enough to power the vacuum table. If you can live with that, you get a perfect power supply for nearly nothing.
The power supply uses a C19 cable which you can get from everywhere. The back connector is a bit special, but from my box of connectors i found the female 2mm gold-connectos from my rc-planes fittet the high power pins perfectly.

Ich garantiere bei meinen Bauberichten und Teilelisten keine Vollständigkeit etc...es wird aus den Teilen gebastelt die gerade herumliegen.
Bitte keine Anfragen zum Bau/Fräsen von Frames, Teilen oder sonstigen Aufträgen. Ich betreibe die Seite rein als Hobby und nutze die zur Verfügung stehende Zeit gerne für meine eigenen Projekte.
Bei einigen Projekten werde ich zu gegebener Zeit die Pläne veröffentlichen - aber auch hier lasse ich mich ungern hetzten ;-)
No waranties for completeness of any contructions, part lists etc.. I build from party i have just lying around in my workshop.
Please, No requests to buy frames, builds, etc.. I run this page in my spare-time and as hobby only. Want to keep my free time to work on my own projects - sorry
I will release the plans for some build at some point in time, but again, please don't ask for unreleased plans, i don't want to get rushed ;-)
