The 3AFS400 Series of filters improves drive systems by increasing the applicable motor cable length and reduces motor noise. These filters can also protect and increase engine lifetime.
Features & Benefits:
Sinusoidal filters 3AFS400 change the output PWM voltage of frequency converters to a sinusoidal line-to-line voltage. Sinusoidal filters enable the operation with very long motor lines. Shielded lines may be at least 300 m long and with a tuned switching frequency even longer. The use of unshielded motor lines is not recommended in industrial applications. In this case an all-pole sinusoidal filter is available in combination with a common-code switching frequency filter 3ACMF for the generation of true sinusoidal power supplies. If the switching frequency is known a customized sinusoidal filter, to reach a bigger length, could be created.
Typical applications are noise reduced drives and the protection of sensible motors.
