Hi all

I have an " Align" brand slow motion table drive on my mill, and as this required a 110v input supply and my mains supply is 240v I bought an "Align" step down transformer to go with it. This has worked well for some years, but then it stopped! I have tracked down the problem to a fuse in the transformer box which has blown – probably because I stupidly caused the motor to stall. I am hopeful that this is the only problem and that replacing the fuse will be a solution.

Problem is I can't read the markings on the Chinese fuse. The drive unit is a Model CE-500S, rated at 110v 90W. A simplistic calculation says 90W divided by 110V = just less than 1 Amp. ( The fuse is on the output, 110v side, of the transformer) Is a 1 Amp fuse enough or should I uprate the fuse to allow for startup current etc? Also, should this be a slow-blow fuse? The original fuse seems to have been a simple quick blow type with a transparent glass body and presumably it had a single wire inside it, but there is no trace of the wire now.

Can anyone offer any advice about this?

Thanks in advance.

Regards

Thanks for your guidance on this. I have now fitted a 5 Amp fuse and all is well!

The fuse is a quick blow type which is all I was able to source locally, but I will order a few slow blow as spares.

If anyone else has this type of problem it may save time to be aware that the green indicator lamp on the Align transformer box only shows the presence of the mains input, and gives no information about the state of the internal fuse or the 110 v output.
