Power-dependent power loss at 230 V_AC
[W/kW + W/A]

4 W/kW + 8 W/A

Power-dependent power loss at 400 V_AC
[W/kW + W/A]

4 W/kW + 10 W/A

Power-dependent power loss at 480 V_AC
[W/kW + W/A]

4 W/kW + 11 W/A

Example: With a nominal input power of 20 kW and a motor current from the directly connected motor of 8 A, the total power loss is
18 W + (4 W/kW x 20 kW + 10 W/A x 8 A) = 178 W
The maximum power loss at 400 V_AC, nominal output and highest nominal motor current is
18 W + (4 W/kW x 42.8 kW + 10 W/A x 40 A) = 590 W
