The following table states the direct current values of the dc-link according to the rated power of the motor
connected to the inverter The current is calculated on the basis of the following:
- 4-pole "standard" motor
- "typical" efficiency for "standard" motors (
- the "typical" inverter efficiency is considered equal to 0.97 (
- mains power supply voltage 3 x 380V (conservative value if referred to a rated voltage of 3 x 400V)
- there are two value columns referring to a continuous functioning (class 1) or to a functioning during an
overload phase (class 2) (150% for 60 seconds).
The current value in column 1 is calculated as
I = P
