Technical details and manufacturing context for Power Module
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Rated Voltage | 600–1200 V | Exceeding rated voltage may cause breakdown.IEC 60747 |
| Rated Current | 50–600 A | Continuous current rating at case temperature.IEC 60747 |
| Switching Frequency | 2–20 kHz | Higher frequency reduces size but increases losses. |
| Junction Temperature Range | -40–150 °C | Exceeding limits may cause thermal failure. |
| Isolation Voltage | 2500–4000 V AC | Test voltage between terminals and baseplate.IEC 60747 |
| Thermal Resistance (Junction-to-Case) | 0.05–0.30 K/W | Lower is better for heat dissipation. |
| Dimensions (L×W×H) | 62×30×8–150×62×30 mm | Varies with current rating. |
| Weight | 50–500 g | Depends on package type. |
| Humidity (Non-condensing) | 5–95 % RH | Condensation may cause corrosion.IEC 60068-2-78 |
| Ingress Protection | IP54–IP65 | Higher IP for harsh environments.IEC 60529 |

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The power module regulates and supplies electrical power to the motor, converting the input power to the appropriate voltage and current levels as commanded by the controller's logic circuits. It enables precise motor speed control.
Typical rated voltage ranges from 600 to 1200 V, and rated current from 50 to 600 A, according to IEC 60747. However, these values are reference ranges; actual ratings depend on the specific model and must be confirmed with the manufacturer.
Higher switching frequency (2-20 kHz) allows smaller magnetic components but increases switching losses. Lower frequency reduces losses but may increase size and audible noise. The optimal frequency depends on the application.
Relevant standards include IEC 60747 for semiconductor devices, IEC 60529 for ingress protection, and IEC 60068-2-78 for humidity testing. Compliance should be verified with the manufacturer.
