SPS01 connections

[Sjoerd Smits]

Hi PA,

We had a little conversation via mail. On your request I opened this topic.

The following is the case:

I have a 2 x 25V 500VA toroid transformer hooked up to the power supply.

Secondary 1 on AC 1 and secondary 2 on AC 2. The output between NEG and POS supply is now 68VDC.

I need to have half that voltage to run my Hiraga amp. So what do I do?

Do I need to put the toroid in parallel, so the current doubles? And how do I connect it? If I do that and feed AC1 and AC2, the fuse blows out of 8 amps.... Do I only feed AC1 or AC2?

Please let me know....

Kind regards,
Sjoerd Smits

You have in other words ± 34 Volts. How much do you require? You can't get lower voltage than this.

Hi PA,

I need +/- 35 VDC for the Hiraga amp.....

Then it's perfect!

Between POS and ground????? I thougt between NEG and POS?????

You connect the amp between, NEG, GND and POS. Don't you have any documentation of the amp design?
