Negative 15v

Negative 15v

2012-05-28 by fuyuhiko

Hi there. I'm quite newbee.
I'd like to make some DIY synthesizers.

First of all, I don't know how to get positive as well as negative 15V DC. I know how to get negative 9V by using batteries. But building the power supply unit seems a bit dangerous for me at the moment.
Is there any good components which I can easily get the power to run modulars, or is there any good suggestions?

I live in the UK.

Kind Regards

There are lots of used linear power supplies on ebay that can be had for cheap. They are in the U.S. so shipping to the UK makes it less cheap but it's still probably the easiest way to go. Power One or Condor are the standard brands so just search for Power One linear power supply or something similar. These usually provide 3 amps so it will power a large system.

If you want to just get your feet wet and power a few modules you could get a transformer and a CGS66 psu board from Ken.

For a safer build have a look at my All-In-One Power Module
Don't forget that US power is 110VAC and UK is 230VAC so check the power
label!!!!

Re: Negative 15v

Thanks for all your kind reply.

Having found some liner power supplies on the internet, I've wondered if I need to get dual supplies or single one with a ground port.
For instance:http://www.tti-test.com/products-tti/pdf-brochure/psu-el-series-4p.pdf
Or should I use the likes of Power One which is to build into a modular?

Kind Regards

I've built two of these:

Best bit about it is you use a low voltage mains adaptor to take the voltage down from mains, reducing the risk considerably. Easy build and I've been using mine for months now with no issues.

I use linear PowerOne or Condor powersupplies. YOU NEED A DUAL SUPPLY. Power One HAA15-0.8 is an example. used, these are almost always cheaper than the parts to build would cost, especially the transformer.

Thank you very much for the information that I need a DUAL SUPPLY.
I think I will try a linear dual supply which is made in the UK as there seems to be less trouble.

Thanks for all the comments.
