Range Conversion
Overloading
Nominal D = 27648 x U / 300 VRMS
range U = D x 300 VRMS / 27648
Overloading
Nominal D = 27648 x I / 1.0 ARMS
range I = D x 1.0 ARMS / 27648
Overloading
Nominal D = 27648 x I / 5.0 ARMS
range I = D x 5.0 ARMS / 27648
Overloading
Nominal D = 27648 x I / 8.0 A
range I = D x 8.0 A/ 27648
Overloading
Nominal D = 27648 x I / 40.0 A
range I = D x 40.0 A/ 27648
Nominal D = 128 x f [Hz]
range f = D / 128
Overloading
Nominal D = 27648 x P / 300.0 W
range P = D x 300.0 W/ 27648
