EMU Emax 1 Rack Wont power on

EMU Emax 1 Rack Wont power on

2014-10-25 by ozgoskar@...

Hi all emax users. Im having a issue with my emu emax 1 rack. it wont simply power on. i measured some of the components inside just to ensure what was wrong but im not getting any values of voltage at all. Am i doing something wrong ? For me, it seems that it could be something wrong with the power socket, since no voltage comes out of it.. hotwiring the socket? hmm. i dont know if its good for the machine since there will not be any fuses there.(we all know theres 2 fuses in the socket) i would like to buy a og one or an replacement one but cant find it nowhere. ? BTW when 'on' all the fuses are OK and the emax still dead.


I will be glad for your answer.

If you are measuring 0V at the connections coming out of the power input module and the fuses are good, then the module is bad (this can happen).

You can get replacement module parts at Mouser.com, I purchased some from there a couple years back.
I don't have part #'s off hand, but if you remove the module you can look up the part #'s then.

PLEASE NOTE- when you order a module it DOES NOT come with the fuse holder section, that's a separate part, so don't throw the old one away!!!

I believe it's about $20-$25 US.

IF you have power at the output of the module, then it can also be the power switch itself which is next in the chain.

The power switch and harness is available from EPR electronics:

Thats right, 0v from the power input of the module. Have you installed one of these in yours? If yes which one do you have? You say the fuse section is a separate thing how should i make it work if the replacament does not have fuses? Thanks for your reply Ted!

I found a identical module so i will order it and try, is it a known issue that modules are giving up?

Hi.
I have a used PSU that works, but is old that I dont use anymore. I pulled it out on my Emax 1 rack and replaced it with a new one. For 10 $ + shipping, I can send that to you. Then you can use it as whole, or pull components.

The equipment is over 20 years old. Components are expected to have a service life and do not last forever.

As I said prior- I had to get an stock replacement module for a unit myself, so yes- I have replaced one before.
