Answer / srij21

Ask the questions clearly .i think u want to know the
rating of the UPS to be used.For this u should know the
load that is to be connected with the UPS.Based upon the
load ,u convert the load to KVA ( if the calculated load is
KW) and ask for the UPS supplier to give the ratings list.
Or else u call the UPS supplier and give him the list.he
will guide you.
