Please can you advise the physical dimensions including the mounting hole spacing... I'd like to also order one of your PSU Enclosures that will comfortably house this transfomer.  

Asked by: David
The dimensions can be seen on the datasheet linked below. Based on the included information it would depend on which orientation you are looking to mount it, but the rough overall dimensions would be 90 x 50 x 52mm so any enclosure with a larger internal space that that should be fine provided adequate ventilation is provided for smaller spaces.

We cannot offer full advice on mains electrical installations, this job would be best left down to qualified Electricians, if you are at all unsure we would strongly recommend consulting a qualified electrician for help and support or to complete the job for you.
