I took pictures of it but not 100% certain, its a little hard to read but looks like it is 120vac, 50/60 hz and 40va
had a us pat no 3144503 pressed into the case
which lead me to this grainger link DORMEYER Class 2 Transformer, 120 V AC Input Voltage - Transformer, 40 VA VA Rating - Transformer - 4X746|DCT-40-120 - Grainger
and it looks identical to what I have except graingers shows 20va on the plate where mine shows 40va. The tech specks on the grainger page shows 40va so…is this thing good enough?
Thanks for your time
