MetroModular Power 202 PSU

Some build pics of the MetroModular Power 202 PSU.
It's a eurorack power supply. Model number: MM1537 v0.1

The various voltage regulator specs are
+12V 1A
-12V 1A
+ 5V 1.5A

Justin's Power 101 board combined the PSU with the distribution board. 

It's a very easy build. There are a few surface mount components, but they are 0805 and 1206.

Justin may have an new version of this by the time of posting, so check his website for updates.

Its a DC/DC converter 18-75V in. 12V out 1.3A

The next 2 regulators are 580-OKI78SR12/1W36C

 Non-Isolated DC/DC Converters 12Vout 1.0A VSIP
Input voltage 15V to 36V
 
tHE 5v converter
OKI-78SR-5/1.5-W36-c

Input voltage 7V to 36V

 

 
 

These diodes are important to help reduce voltage spikes (flyback).

Gotta love  the choke.
580-51105C

 Inductors, ferric beads, noise reduction methods, etc
 

There are 2 capacitors used in this build.
A 10uf and a 22uF ... both SMD.
The caps have a very large footprint... tricky  to solder on.




Don't forget to solder the remote




I'm using this Meanwell PSU
709-gst60a24-p1J
 

It's output is 24V DC @ 2.5 A
:
90V AC to 264V AC
