Sine wave filter N CNW 933

Three-phase sine wave filter

DESCRIPTION

NEW SERIES!

The new series not only scores points for its faster delivery time, but also for its resource conservation and increased efficiency.

Sinusoidal output voltage – Save costs and ensure trouble-free operation. For particularly long cable distances of > 100m between the frequency inverter and motor, the shielded cable used for EMC suppression can cause capacitive coupling. In such cases, a conventional motor choke cannot provide sufficient damping. The sine filter is a low-pass filter consisting of inductance and capacitance, thus having a very low resonance frequency. As a result, it is able to generate a largely sinusoidal current. The operation and loss balance of the asynchronous motor behave as they would during normal mains operation. The typical motor noises during inverter operation do not occur, and depending on the system, shielded cables to the motor can be omitted. Losses and heating are greatly minimized, and the leakage current is reduced. Longer motor cable lengths can be used. The motor insulation is protected, thereby increasing its lifespan. The sine filter also effectively dampens conducted interference in the lower frequency range. Losses and typical noises in the motor laminations are reduced.
