Delta linear PSU modules

Hi, these were bought in a lot by me. They are older but unused as these were kept as spares for Röntgen machines but none broke down 🙂 As can be seen they are +/- 12...15V 0.2A and 1 x 5...6V 1A.

Quality of Delta stuff is excellent and these practically never break down. Official data sheet ripple/noise figures are 0.5 mV ripple/noise till 20 MHz but they are more silent. A good transformer is used and only the bulk cap is electrolytic. The circuit is discretely built around a MOSFET pass transistor and it is LDO which surprised me really. I changed the bulk caps on a few but the old cap was OK so maybe unnecessary. The 5V version only has 1 x 10,0000 µf 16V cap which I replaced for CDE 381LX in a few I use myself. The other caps are the famous Philips Solid Aluminium which are very good. Both 230V and DC connections are made with flat AMP connectors.

Good for upgrades of digital stuff with A quality linear PSU's. In a DAC they can supply both the output stage and the digital part. I haven't found the opportunity to check if the 5V can be modified to 3.3V.

40 Euro a piece so a PCB with 1 x 5U15-15 and 1 x 5U5. Ex shipping. Within Germany, the Netherlands, Belgium, France I should be able to do it for 50 all in.

NO shipping to the UK (30 Euro!!) or outside EU.
