Frequency converter
Erfi
The inverters allow the voltage withdrawal at a certain frequency. All inverters are parameterised in the factory.
Use: Control by three-phase motors
Sinusoidal filter: A factory-made and integrated large sinusoidal filter avoids emitted interferences to the feed lines of the motor.
A low limit frequency guarantees low emitted interferences.
Thus a good distortion factor of 0,75 A is obtained.
Fixed frequency: 400 Hz
Output: Voltage: unearthed
Three-phase: 200 V
Phase zerol: 115 V
Current: 4 A
