110 volt PSU compared to a 220 volt


Recommended Posts

Has any one really had a look for the differences between the 110 and 220 volt supplies.

I have started comparing a Jap PSU (100-127 volt) to a Aus PSU (220-240 volt) and so far the two main differences is the Aus spec has a extra power filter on the AC input and the Jap version has a hidden link under the main power filter

The part with the red star is on the 220 volt and on the 110 volt there is a link at the red arrow

The blue arrows are the only difference I have seen so far as far as the different input voltage and the link is doing the same as a universal Xbox PSU I have that has a 110/220 switch.

It is  looking like you could add a link to make a 220v into a 110v or remove it to make a 110v into a 220v version.

The transformers might be different. Have you measured them?

So far the 3 main transformers that I have checked have the same part number on them and a resistance test give the same readings.

Are the two larger electrolytic capacitors to the right of the link pointed to by the blue arrow the same voltage rating?

I believe those two on 220V PSUs are rated at 450V while 110VAC use 250V rated caps.

The main filter caps in both versions are 3300uf 200volt there is also a varistor (MDC M151) that are rated at 150 volt across each of the main filter caps.

The N channel Mosfets are different but the specs are the same.

Both are Delta brand supplies from version 1.0 Xbox's.

Both supplies I tried are for the version 1.0 - 1.1 and are the Delta Electronics branded PSU.

The tick box markings on the 100 volt is 100-127v and DSPN-96AP the tick box's for the 220 is 220-240v and DSPN-96AP-1

All the other components I have looked at are the same and even the Pico fuse(F1)is a 3.15amp on both so I don't see why it could not be converted.

I removed the J11 link on the 100 volt supply and tested it up to 255 volt AC as the supply here could be 221 to 251 with a average of 240 AC 50hz and all the outputs ( 3.3 , 5, 12) tested fine even with thee AC input down to 170 volt AC and below 165 volt AC the supply would only give the 3.3volt standby and not the other outputs

I can see no reason why you could not add the link and convert from 220 to 110 volt.

Please note I have not tested converting a 220 to 110 ( I have no need to as we use 240 volt ) and I take no responsibility if you get hurt/killed trying or you let the magic smoke out (blow it up) and I have only tested the Delta brand as mentioned above.

      I just tried to power up a 1.6 crystal, and nada, so I checked the PSU, and there's nothing on the 3.3V standby. I CBA faultfinding, as the parts with shipping will likely cost as much as a PSU, so I need a PSU for a 1.6. .. does anybody have one?  Cash (PayPal) or exchange for 1.0 - 1.1 PSU.
      Also need an OLED OpenXenium with daughterboard, if anyone has one.

      So I need to bridge white to black, think it's a 1.6v

      But do I also need to bridge blue to black to keep it powered on? It's going to power one fan for a 3D printer using the molex connector

      Hello everyone, my name is Vitalij and I am from latvia ! 
      I have two xbox v1.1 and v1.6  in 1.1 dump of something (red-green light), but fully working power supply and 1.6 working, but the mosfet burned out in the power supply.
      Is it possible to make a 1.1 to 1.6 PSU, can there be a complete manual or something? I found a guide showing how to make from 1.1 to 1.2-1.5, but as I understand it, this does not work for me.
      Could you please help with this?
      Then I saw the topic
