What is the different between VLN and Vin

What is the different between VLN and Vin

(OP)
Hello all,

I'm looking at the spec datasheets, One says 57-120V(LN) and the other one says 57-120Vin. My understand is, the first one means 57-120V (between LINE or LIVE and NEUTRAL), and the second one means 57-120V "input voltage". Are they talking about the same thing or I'm completely misunderstood? Can someone please confirm?

Your help would be appreciate!

RE: What is the different between VLN and Vin

That is not a spec, that is a catalog number explanation chart. Vin is telling you the input voltage range selection. That unit will not care how the voltage gets there; V(L-N) or V (L-L) is irrelevant as far as it is concerned. It is just looking for a voltage somewhere between 57-120VAC. Most likely you will be attaining that through a PT and the concept of whether or not to use a grounded neutral on your PTs is a separate issue from what the meter needs to see.
