Production according to UL insulation system E251513 possible
Sinusoidal output current - save costs and trouble-free operation.
For particularly long cable lengths of > 100m between inverter and motor the shielded cable for EMI suppression used can cause a capacitive coupling. A conventional motor choke can not provide sufficient damping in such cases.
The sinusoidal 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.
The sinusoidal filter also attenuates the conducted interference in lower frequency range very good. The losses and the typical noise in the motor plate can be reduced.
