Kenwood PS 36-30 Powersupply
« on: February 26, 2018, 10:50:32 pm »
Hi all,

Its been a long while since I last had time to fuel my electronics interest, the last time was when I was taking my Electronics A-Level in 2011-2012 but now I have more time.
I managed to pick up this Kenwood PS 36-30 Switch mode powersupply on ebay for ~£27 last week. It was advertised as powers on but not tested but the good news is that it works!

Manual can be found here for the full range of supplies http://www.cieri.net/Documenti/Kenwood/Test%20Instruments%20-%20User%20Manuals/PS60-6%20-%20Regulated%20DC%20Power%20Supply.pdf
As its been a while since I studied electronics I'm not 100% sure how good the specs of this are. Some things I can pull out though are:
0-36V
0-30A
Ripple: 100mV P-P / 15mV RMS
Transient Response: 2ms
Power Consumption: 2600VA (Am I right to assume then this can provide the full 30A at 36V?)

As it also appears to be used mainly in a rack mount environment it has full remote control options available via GP-IB, I might take a crack at using them at some point.
Like Dave recommends though, it has 10 Turn pots for voltage and current adjust, Constant Voltage and Constant Current.

There is some issues though, as you might see from the third image, the unit must have been dropped at some point and broke the mains power cover, before I go using this for anything major I really want to fix this somehow. Any suggestions are welcome. Same goes for finding a way to replace the missing front bezel.

Interesting looking supply, little crusty, would be nice to see whats inside when you crack it open !.
As for the damaged/missing plastic bits perhaps 3D printing (ABS) new ones might be the go.
Assuming you have suitable software access to design new ones using the existing bits as a template.
The odd multimeter or 2 or 3 or 4...or........can't remember !.

Already opened, see the flickr link for photos!

I could probably do it, but that would be a complete learning experience and will take time. It had crossed my mind, I was just hoping for something quicker.
