48 VDC 3.3A 150W Regulated Switching Power Supply

so basically, just wire this up, and plug it into the wall and plug in the dc adaptor into what I need powered(amplifier)? this is about the same price as what a power-brick would be for the same application, but I would like to keep the brick hidden...

Asked by: bcboyz86
Yes. You will want to double check the output voltage with a volt meter, but it should be very close to 12 volts.

Model: PS-SP11117- Can I series two of these so I get a split rail power supply for an amplifier; i.e., get plus and minus 48 v w gnd for amp?

Asked by: donovanpl123
Indeed, this is what is recommended for the International Rectifier based class D board, which requires a split supply.This will also work nicely with all the chip amplifier designs, nearly all of which require a split supply. However, I must remind you (and other readers) that dual 48VDC is some SERIOUS juice, capable of causing severe or fatal injury. In other words, if you are getting into the high output amplifier business, you need to be CAREFUL in ways you don't quite as much (though you can still get a nasty jolt from 30VDC) with the lower powered stuff.

Is it wise to use a switcher power supply for a analog amplifier?

Is it possible to use two Model: PS-SP11117 arranged in series for a amplifier with a split power ssupply for an amplifier? So, + - 48 volts.
Asked by: donovanpl123
Yes, indeed, it is possible to wire these in series. However, make sure that the two supplies' chassis are separated or insulated from each other, in case the supply is wired with ground to chassis (most of these are not for just this reason, but why take the chance of seeing an unscheduled fireworks display in your listening room). These are called 'industrial' for a reason--they are designed to drive power loads to full spec without self destructing. In fact, shorting one out would probably not cause fireworks, because these have robust overload protection.
