The Lenze speed controller on my Boxford Mill has just gone bang...
The offending part can be seen here...

The big black box has burn marks around the base, so I am guessing it is that.
 
I have done a search on google using all the numbers on it but have come up with nothing as I don't even know what component it is?
DC/DC converter?
 
Anybody got any ideas? I'm happy to try and replace it if I can source a suitable replacement. Failing that can anyone recommend a 180v permanent magnet DC controller?
 
Thanks
Simon

Many thanks for the link... Looks promising... I'll report back.

Hmm... Nobody seems to know what the output voltage should be for that transformer.

Replaced the transformer but it still doesn't work correctly. It pulses the output. So I replaced it with a KBIC. If anyone wants a faulty LENZE 534 controller to repair theirs with then let me know!
