Couldn't find an answer to this by searching, so I hope someone might be able to give me an answer.
If a transformer is labeled as (for example) 25 V.C.T. @ 2 A, is there a way to deduce the VA rating from that information?
I found a formula on the web as follows:
WATTS = VDC x IDC (output)
VA = 1.4 x ( WATTS + 2 IDC* )
Which would make my example transformer:
WATTS = 25 x 2 = 50 W
VA = 1.4 x (50 + 2 x 2) = 75.6 VA ????
Am I on the right track with this? Or is there no way to find the VA rating from the label i mentioned?
I haven't seen the transformers in question in person, got the information from the website of my local electronics surplus store. So there may be a VA rating labeled on the transformers as AFAIK.
Just curious if that information is sufficient to figure it out...
Grateful for any help.
