4. Key Features

1. Sine‑Wave Smoothing: Eliminates PWM voltage spikes, extends motor insulation life。

2. Long Cable Operation: Supports motor cable lengths up to 100 m。

3. EMI Compliance: Meets EN 61800‑3 Class C1/C2 with unshielded cables。

4. Zero Leakage Current: No earth‑leakage current, safe for sensitive systems。

5. Group Drive Capability: Suppresses bearing currents in parallel motor connections。

5. Compatibility

• ✅ Suitable for MOVITRAC 31C and MC07B series inverters.

• ✅ Matches 4.0 kW motor power class (@ 400 V).

• ❌ Not compatible with MOVIDRIVE B or servo applications.

• ❌ Use only in V/f or VFC modes; do not use in hoist applications.

6. Operational Notes

• Derate current 6% per 10 Hz above 60 Hz.

• Consider voltage drop across the filter during planning (reduces motor torque).

• For EMC compliance, follow SEW’s EMC‑compliant installation guidelines.

7. Status

• Active (standard product), available new/used/refurbished from distributors.
