Sinusoidal input current – save costs and trouble-free operation.

The line reactors in fully encapsulated version are specially designed for rough environments and offer a very good mechanical protection of the component. The fully encapsulation allows design up to protection ratings IP 66.

For particularly long cable lengths of > 100m between inverter and motor the shielded cable for EMI suppression used can cause a capacitive coupling.

The sine wave  filter is a low pass from inductance and capacitance and has a very low resonance frequency. So it is able to generate a largely sinusoidal current. The operation and the loss balance of the asynchronous motor behave like the normal mains operation. The typical motor noise with converter do not occur and a shielded cable to the motor can be dispensed. Losses and heating are greatly minimized and the leakage current will be reduced. Longer motor cable lengths are possible. The motor insulation is protected, thus increasing the service life.
