| Output Frequency | 0–400 Hz | Higher frequency for high-speed motors. |
| Overload Capacity | 150% for 60s | Heavy-duty applications require higher overload.IEC 61800-2 |
| Efficiency | ≥97 % | At rated conditions; IE2 or higher.IEC 61800-9-2 |
| Control Accuracy | ±0.1 % | Speed regulation accuracy for closed-loop. |
| Ambient Temperature | -10–50 °C | Derate above 40°C.IEC 61800-2 |
| Protection Rating | IP20–IP54 | IP54 for dusty or wet environments.IEC 60529 |
| Enclosure Material | Aluminum/Plastic | Aluminum for heat dissipation; plastic for cost. |
| Weight | 2–150 kg | Depends on power rating and enclosure. |
| Dimensions (W×H×D) | 100×200×150 – 600×1200×400 mm | Varies with power; check mounting space. |

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The typical input voltage range is 380–480 V AC, as per IEC 60038. However, other voltages may be available; always verify with the manufacturer for your specific model.
A VFD rectifies AC to DC and then uses an inverter with IGBTs to produce a variable-frequency AC output. The motor speed is proportional to the frequency of the supply, so changing the frequency changes the speed.
The overload capacity is typically 150% for 60 seconds, as per IEC 61800-2. This means the VFD can handle 1.5 times its rated current for a short period, which is important for heavy-duty applications.
For dusty or wet environments, a protection rating of IP54 is recommended, as per IEC 60529. The VFD range offers IP20 to IP54, so select based on your installation conditions.
