Thread: Keypower's 250w DC-DC converter

Well, I will notify everyone in on the group buy via email by the end of this week. We need 3 more people to get the $149/unit deal.

Here are the instructions again incase anyone wants in on this group buy...

1 - Make sure you definitely want the DC-DC Converter. Here's the unit. And here's the last post on the unit incase you want more feedback

2 - Post in this message that you're in and send me an email with your shipping address, name and info.

3 - Also, please sign up an account with Paypal. They are a secure online form of payment transactions via bank or credit card. I chose this site because of the uniform payment method, so as to avoid checks comming in from this way and that.

Once we have 10 people that have done these three things and confirmed it with me via email, I will email everyone with the total and order the units.

Thanks Again!

I was waiting for yours, but just don't have that much patience (or flame-retardant suits).</STRONG>

well, I have finished the PCB design, but still have to check it... the supply I am working on is a foward converter but with out the old PS board, it is AT, and can output 8amps on 12volt rail MAX, and 16amps on the 5volts MAX, But not at the same time.(The 5volt, and 12volt equal 16amps total, no more)
The power good signal is obtained the same way the sproggy supply does. most components are availale from the only PS board, including transformer (that requires rewinding) caps, inductors, and hopefully the -5volt regulator... any one interested??? If I do make these, (I am not promising this) they will be sold for around $150-$200 Australia, thats just $75-$100 US!!! and its higher power.... but that doesn't mean that I will actually get around to making them...

although I am working on making an ATX one as well, should I have a battery built into the supply for standby, or just use the car battery???

If this one won't suit your needs, I'll be making some more of the MPBS1s really soon.

But I will do a pilot run on ebay.. If I didn't need the small size, I'd go with the keypower one. It looks like a great supply, plus, you can run a power hungry system.

I'll go for one.

For $150, Count me in if shipping isn't more than 10 bucks.

I'm in too

That sounds like 10 to me

Okay, I am redesigning the supply to match, or better the keypower one... we'll see if I manage...

Im in too. I allready have Paypal.
