I have had the parts laying around for a while and with the arrival of the 2U high 19 inch chassis it was time to put it all together.
A 12V (13,4 actually) power supply for in my rack.
Some specs:
DV voltage : 13,4 Volts ( i can’t up the voltage more on the 12v supply)
DC Current: 12,5 Amps ( all tho it will be fused at 10 Amps.)
AC voltage : 230V
AC current : 2Amps
Basically i did it the lazy way and used a Meanwell PSU from the RS-150 series.
Spec’s found here: http://www.meanwell.com/webapp/product/search.aspx?prod=RS-150
I added a extra capacitor for buffer a 40VDC 19000uF, included a bleed resistor of 330Ohm 4 Watt. Giving it a 19sec bleed time.
When done it will have 8 terminals on the front. Also in the near future i want to add an expansion port in the back and make an other 8 terminals in a separate housing.
The volts and current meter is a 100DVC / 10 Amp unit from Aliexpress.
Here are some pics. And yes my columndril isn’t really steady so one or two terminals are a bit off….
And the end result
