CoCo2 26-3134A with 230V~ ???
Posted: Mon Oct 06, 2014 10:03 am
Did anyone know a power supply solution for a CoCo2 26-3134A with 230V~ ?
In http://www.colorcomputerarchive.com/coc ... ndy%29.pdf i found some informations:
* power transformer provides 17,2 VAC, center-tapped, ad 1.8 amps RMS
* -5V are only for RS-232C and not used anywhere else.
Must i have a transformer with AC output? Or can i use a Switching Supply solutions with DC output?
What ampere is needed for +5V and -5V ?
It's seems that a power supply with -5V is hard to find.
I found theses Switching Supply solutions:
* MeanWell PD-2505: 25W 5V/2.5A -5V/2.5A
* MeanWell RT-65A: 66.1W 5V/6A 12V/2.8A -5V/0.5A
* RECOM Power RAC10-05DC/277: +5V/1A -5V/1A
* TDK-Lambda KMD15-55: +5V/1.5A -5V/1.5A
But they are not really cheap and it seems that i can't buy every of them easily in germany.
The MeanWell RT-65A costs ~20€
Maybe a simple transformer is cheaper... I found this:
* Block NT 12VA 2X6: 2x6V 12VA 1,08A - 11€
* Block EL 54&18,8 : 2x6V 16VA 1,3A - 7€
* Block EL 18/6 : 2x6V 18VA 1.5A - 16€
* Weiss UL 506 : 2x6V 18VA 1.5A - 7€
* Block EL 60/25,5 : 2x6V 25VA 2A - 9€
