ORD-1 power supply

Postby laviritel » 12.02.2014, 07:52

Hello everybody!

First of all i would like to say sorry for my English.

I'm interesting to build ORD-1, but there is one problem, I can not understand which power supply should I use? For example, can I use my old laptop power supply? It brings me about 19 V and ~2 A, of course laptops power supply output is DC. Or should I use a transformer from 220 AC to 14 AC?

If the second is true, there is a little problem, I have never worked with transformers and therefore i don't know which one I need to buy and how i can connect it.

Thank you!

welcome laviritel,
I do not no. In the chematics http://bazaar.launchpad.net/~rocrail-hardware-team/rocrail-hardware/trunk/download/rob%40planf-20090116111643-aw9y8gypyy5goam9/ord1.pdf-20090116111631-5ws1woqctvxylrcf-91/ORD-1.pdf is describe to use a 16 V AC or a PC transformer. Maybe other one can answer this.
Best regards
Stefan

Hi laviritel,

therefore to use a transformer with only one secondary winding i can't recommend.
You need a transformer with 2 secondary windings, each with the necessary voltage e.g. 14V.
If You use gauge N then also 12V may be enough.

For connecting it at CONN_3 (J3) of ORD-1 You need ensure
that the two connections of every winding must be connected in the right order.
If we assume the first winding has wires "A"+"B" and the second has wires "C"+"D",
so You must connect "A" at clamp 1, "B"+"C" together at clamp 2 and "D" at clamp 3 from J3.

Thank you for your fast responses!

Yes, I use gauge N, so for me 12V is enough.
It would be great to use a PC power supply. But i check one its output is DC,
it has 12V and 16.0A.

If I can not use it, RainerK, can you please give me link to a page, where I can buy a transformer. There is no problem which e-shop it would be, i just need to see it and read about its specs.

In attachment there is photo of my PC power supply.

Hi laviritel,

the ORD-1 need a two polarity DC supply if You not use a transformer with two windings.
If Your PC supply provide +12V and -12V, so You can use it, but 12V is even for N gauge not enough.
You should consider that the ORD-1 has an internal loss near 2V, so You get in this case only 10V at the rails.

So I can only recommend an transformer as suggested above
and as an example like this: http://www.reichelt.de/?&ARTICLE=100656

if you need an symmetric +/-12V output you can't use an PC power supply. As your picture shows +12V delivers 16A but -12V only 0.5A . The result is a maximum power of 0.5A.

Thank you for all responses!

Actually in Latvia i found only this "INDEL Transformator". Its specs are:
    Input: 230VAC
    Performance: 34VA
    Output 2x15V


There is direct link

Sorry, but the page is not completely translated in English.

Is this ok or should I search for a transformer with higher performance?

Thank you!

Hello my friends! I need your help one more time. Today I have build an ORD-1 and tested it. But, I think, my ORD has a problem. When I power it on, LED 12 is switching on for 2 sec. and LEDs D16 D18 D19 D20 are on. After 2minuts on my traffo is very hot. Is there something wrong?

The ORD-1 is no longer supported and not recommended as DIY project.
Use the ORD3 instead.

Thank you for response. Unfortunately I can't find KBU6A and FED 100u. Can I replace them with similar? For example, can I use this one:
choke:
DPT100A5; 100uH 5A d=16.5mm RM9 0.12R or DPT100A6; 100uH 6A d=16.5mm RM9 0.065R
Biggest problem is with bridge, I cant find something similar. There is no bridge with nominal current 6A. :|

The ORD3 can be ordered as Kit by GCA.
