• Protection Class: IP20

• Weight: ≈ 1.85 kg

• Motor Power Rating: 2.2 kW

4. Key Features

1. Sine‑Wave Smoothing: Significantly reduces dv/dt, voltage spikes, and bearing currents.

2. Motor Protection: Extends insulation life and suppresses discharge currents.

3. EMI Reduction: Meets EMC Class C1 with unshielded cables.

4. Long Cable Operation: Supports motor cable lengths up to 100 m (vs. ~20 m without a filter).

5. Zero Leakage Current: Earth‑leakage current is 0 mA.

5. Compatibility

• ✅ Suitable for MOVITRAC 31C (e.g., 31C022‑503‑4‑00) and MC07B series inverters.

• ✅ Matches 2.2 kW motor power class.

• ❌ Not compatible with MOVIDRIVE B or other SEW drive families.

6. Operational Notes

• Operate only in V/f and VFC modes; do not use in CFC/SERVO modes.

• Not intended for hoist applications.

• Account for voltage drop across the filter during planning, as it reduces available motor torque.

7. Status

• Discontinued (no longer in standard production), but new, used, and refurbished units are available via distributors.
