Output Current is higher than Input Current to a DriveProduct Line:
All Variable Frequency Drives Environment:
All Variable Frequency DrivesCause:
Basic Electrical TheoryResoultion:
The input current may be less than the output current because the output voltage of the drive may not be equal to the input voltage.
A drive is a power converter. The power in (Volts x Amps) will equal the power out (Volts x Amps).
When running at less than full speed the output voltage will be lower than the input voltage, which means the output current may be higher than the input current.
