Unhappy Control 24 power supply died :-(

Apparently the power supply for my Control 24 died. I know of places i can ship it for repairs, but i want to avoid that if possible. Any ideas where I can get my hands on a power supply?

thanks!

Lives for gear
I'm not %100 sure on the control 24, when mine died I got a replacement from Avid and because it was a known issue it wasn't that expensive. But I believe Skynet (really creepy name choice, hopefully they aren't working on AI in a back room) is the company that makes most/all the power supplies for avid. This is their site:

Skynet Electronic Co., Ltd.

They (at least used to) have a guy in cali who can test and recondition them as well, although if your PS was a rev 1 you are probably better off swapping to the newer switching one that avid was (is?) offering. It creates less heat and I think insufficient ventilation in there was the prob in the first place.

Fair warning it is a pain in the ass, they hotmelt glue all the molexes in there to make it extra difficult to remove them.

Control 24 PSU

In case someone comes across the same switching power supply failure that I experienced recently after a main AC problem, here's a possible solution.
I removed the blown T5A fuse soldered on the circuit board and from there ran two wires to a standard fuse holder on the back of the PSU rear pannel, which implied drilling through two sheets of metal near the on-off switch. When I turned the board back on, the new fuse blew instantly.
Then I found some info about checking the PSU FET transistor, which turned out to be kinda loosely bolted onto its radiator (with no heatsink coumpound), meaning it had probably heated up badly, making it more likely to die when stressed. I replaced it (8€) and the board came back to life ! The specs at RadioSpare are SPW20N60S5, Canal-N, 20A, 600V, A-247.
Therefore, I strongly suggest to working Control 24 owners to open the PSU pannel and crank the **** out of all the bolts holding heating componants to their radiators, and if possible add heatsink coumpound everywhere !

Also know that I asked Skynet for the schematic of the PSU but they refused to send it to me as their hands are contractually tied by Avid...

Hello Mups,

want to says a big THANK YOU for SHARING your experience.

My Control 24 smells and stops working after a long session day.
The soldered Minifuse blows also after replacing.

I try to measure the reason of the shortcut,
after leaving the primary side with rectifier bridge and transformer, I found a short on the secondary side of the power supply.
Moving several components solder pins on one side to find out which one is responsible for the shortcut, I also find the POWERMOS FET transistor complete shortcut state between all three pins, also in unsolder state.

I replace the MOS FET transistor with SPW 20N60S5 TO 247 and also the mini fuse soldered T5A and runs the control 24 in test mode since 2 hours without any problem.

Please beware of the small connectors for the meter bridge boards, which could be pulled off by open the power supply section.

Thank you again, I'm very happy to be a part of this forum sharing valuable and helpful informations for us gear fans.


In case of being in a situation without enough knowledge to measure and find out the broken components this link could be helpful for all Control 24 users in europe.

Greetings to you, and a big THANK YOU once more to Mups,
