Register Modbus Smart-UPS VT n + 0 n + x

[BillP]

Dear, I have the following query:

The following data is displayed in the Modbus register map:

Percent of Maximum Output VA's Phase A @ n + 0

Percent of Maximum Output VA's Phase A @ n + x

What does @ n + 0 and @ n + x mean?

Thank you.

Hi Hector,

'n' refers to your load 'n'eed or capacity in terms of redundancy. 

Those register values are Percent of Maximum Output Volt-Amps Phase A @ (at) n or your load + zero redundancy and Percent of Maximum Output Volt-Amps Phase A @ (at) load + x redundancy with X being whatever redundancy you currently have.

Depending on what UPS you have - Smart-UPS VT I think?, this may be documented in the UPS user's guide too as to where to check your redundancy.
