Powertech/Jaycar MP3088 Power supply information required.

[VK4TIM]

Good morning all,

Just wondering if anyone out there has any circuit diagrams for the Jaycar/Powertech MP3088 25A variable power supply please?
These are a linear supply, probably about 15 years old.

I have one here that needs a little TLC, the regulator is not regulating and I have full filtered rectifier output with no adjustment available, about 25V DC out.

I can't find any diagrams for this supply out on the net...

Thanks in advance,

Tim.

Hi Tim,

If it's the PS I'm thinking of, it was also sold under several 'badges' including Manson EP-925 and Palstar PS-30

Some info & circuit in the link.



Hope this helps.

Many thanks MTV,

That is indeed the same power supply.

I shall print out the pictures. That is a big help.
I'm sure there's others out there who have these things and want some info.

Regards,

Tim.
