This is an affiliates page which hopefully will pay for the maintenance of this website one way or another.  Having personally tested the Dc-DC 10-32V to 12-35V mobile switcher it works very well – note though that the power supply does not have isolated (-) and (+) poles.  The input (-) and output (-) are bonded together. Those wanting to do a little bit of DIY can wire wrap a separate secondary but I have not tested this – it is a work in progress.

We used two of these modules on a transformer with 0-12V 0-12V secondaries through two bridge rectifiers to get a split rail supply of +32 0 -32V rails. It is used to power two TDA7293 modules running at about 50W into 8 Ohms.

Parts-ring concentrates on the DIYer and in what better manner than playing around with some pretty cost effective boosting switcher supplies.

The company that sources and supplies these products also sells a 480W adjustable 48V supply. This makes these highly affordable SMPS a very good solution for those wanting to power their +/- 50V supply amplifier kits.  We have not tested them yet but watch this space.
