MOTU Ultralite MK1 power supply

Post by mvagz704 »

Hello everyone, and a happy new year (little late, i know, but anyway..!) :)
I have an Ultralite mk1 and the power supply was "blown". I still use the MOTU with bus power, but i would like to fix the power supply anyway. I opened it up and i saw a bad capacitor, a probably bad resistor and surely a diode gone bad. The only thing i cannot identify is the diode which says:
EIC60
22OD5
i think ...(doesn't seem to have a standard numbering, but i am not electronics-savvy anyway..)
Yes i know, std power supplies are really cheap, but i always like to fix things (if i can) first.
Anyone can help please?
Thank you in advance.

Doing a search for EIC60 22OD5 brings up this thread.
Yes i know, std power supplies are really cheap,
Here's the one that MOTU sells.

These do take a standard power supply. The specs are in the manual and online.
http://motu.com/techsupport/technotes/Traveler-DC-Power
and it's wide ranging:

What kind of DC power adapter do I need for the Traveler or UltraLite?

As alternative to powering the Traveler via the FireWire bus or battery, or the UltraLite via the FireWire bus, you can use a DC adapter.


The Traveler or UltraLite needs a 12 watt DC power adapter. It can be of any polarity (tip positive or negative), and of any standard voltage from 10 to 24 volts. The easiest way to achieve 12 watts is to use a 12 volt, 1000 mA (1 A) power supply.

If you are using DC power with the Traveler make sure to turn the Traveler's "FireWire Bus Power Enable" switch to Off.

For more info on powering the Traveler or UltraLite via your computer's FireWire bus, please see this tech note:

They are really cheap, but that's besides the point here.. I use my MOTU with bus-power and i already have a 3rd party power supply.
I just wanted to find out how to fix the old one (the stock one), just for the sake of fixing!!! :arrrr:
