Group buy: DCT03 DC trap (filter) for toroidal transformers

[peranders]

I have made a bigger DC filter for getting rid of the hum in big toroidal transformers. The pcb has 105 um copper and more than 1 cm wide traces. If the interest is big enough I will go ahead with a group buy. The diode package can handle 12 amps and 68000 uF/16 V caps will fit. This pcb is perfect for those who like it big.

I see that I have got some boards in interest. Let's hope we reach the set goal.

 

[peranders]

The interest is increasing. That's good.

Under what conditions (or VA rating) would the ~03 version be preferred over the ~02?

 

[peranders]

Some people want simply more and in case you have more than 6 amps you will also need it.

 

[peranders]

The DCT02 has 6 amp diodes so this could be a practical limit but for 110 V countries this could be a bit low but since you can add more capacitance you will get a very good current capability plus that the diode chain can handle more. I have four diodes in series so the DC limit is also increased.

Hmmm would be interested too

 

[peranders]

Don't forget to sign the list.

 

[shattered_dream]

Will do tomorrow

 

[shattered_dream]

Done....

 

[peranders]

Nice to see that the interest is increasing.

 

[shattered_dream]

What do you think wenn will you start?

 

[peranders]

It depends when the interest is enough.

 

[AmpUtator]

I'm in. First time I've used wiki. Looks like I edited it okay.

 

[peranders]

Yes it went OK. Did you notice the "Edit icons"? If you activate those you can edit a chapter only.

 

[AmpUtator]

Thanks for pointing that out. I'll have a look.

 

[peranders]

The interest is far from 100 boards but a will move the time plan a bit and see what happens.

 

[peranders]

I have a few more boards on the interest list so if you add more this group buy will start.

 

[shattered_dream]

Just saw that my name at the interest list is wrong.... Must be "shattered_dream"..

 

[peranders]

You can change it yourself (wiki page you know) but I have fixed this. The interest has increased a bit.
