WENtechnologyUnipower Product Family


The Unipower HPL series load monitors display power in units of %kW where this value represents a % of Full Scale for the unit as configured.

Full Scale Power (100%kW) = x V' x I'

Full Scale Power (100%HP) = x V' x I' x 1.341

where V' is the rated voltage printed on the side label and
where I' is the actual Full Load amperage for the unit.

To convert %kW, first calculate the Full Scale rating and then pro rate accordingly.

Input Power (kW) = x V' x I' x %kW

Input Power (HP) = x V' x I' x %kW x 1.341
