ante Posted February 26, 2006 Report Share Posted February 26, 2006 Hi astra,It’s quite a lot of power (160W), do you plan to build it or buy one? There are some SMPS with triple output voltage but 15Volts are not the standard here. If you need light weight and a small unit it must be primary switched. If size and weight are no big issues you can perhaps use a secondary switched or even a linear PSU.So, where are you going to use it and for what kind of equipment?

prateeksikka Posted February 27, 2006 Report Share Posted February 27, 2006 5 V SMPS is easily available in the markets.why do u need to build it? Quote Link to comment Share on other sites More sharing options...
ante Posted February 27, 2006 Report Share Posted February 27, 2006 Hi prateek,You are correct about the 5 Volts part but the -15V and +15V is not that common, especially not in one and the same unit and at this high current. If -12V and +12V would work it is not that hard to find. Quote Link to comment Share on other sites More sharing options...

ante Posted March 1, 2006 Report Share Posted March 1, 2006 Hi astra,GSE means Ground Support Equipment.It’s a tough one, this is the closest I could find: http://www.v-infinity.com/pdffiles/VMPT-200C.pdf The –15Volt is only 2.4A and you must use a fan to cool it, can you live with that? 8) Quote Link to comment Share on other sites More sharing options...
