I am making a Bench top PSU and have found a transformer that will suit my needs but one thing I am confused about is the dimension sizes.

It has the following, I know D=Depth, W=Width and H= Height, but L and A are confusing.

A: 82, D: 60, L: 69, W: 35, H: 59
sizes in mm

L for length does not make sense since we have width and have no idea what A would stand for.
 
That's... Odd. Normally I'd expect length OR depth, width, height. A could be area but an 82mm area makes no sense at all for those other measurements, not least because it's not in mm^2. Have you got a link to the site?
 
Found the answer.

A=Distance between mounting holes
D=Depth of coil
W=Width of case
L=Length of case
H=Height of case
 
Hmm, no datasheet. All I can suggest is that if size is critical, find a site that can provide the datasheet, if not then make sure your case exceeds those measurements I suppose.

If I were to guess again having seen the transformer, I would say that one set of measurements refers only to the size of the chassis, one of the others is the length including mounting tabs and the fifth is the width/depth including the outer coil, but I have no idea what that would achieve.

Tree'd! I was almost right though.
