Product Advantages

Compact size and high integration with significantly reduced overall dimensions; modular design with high EMC margin.

Maximum torque-per-amp ratio, space vector modulation, and overshoot control reduce switching losses, improving efficiency by 2%.

Field weakening control technology enables higher motor operating speeds.

Torque compensation reduces noise and vibration by over 90%, with harmonic reduction also exceeding 90%, ensuring stable and efficient low-frequency compressor operation.

Undervoltage frequency reduction and deceleration shutdown strategies reduce compressor wear and extend lifespan.

Nanosecond-level overcurrent protection, under/over-voltage protection, and overcurrent/overpower protection. Fault protection logic safeguards both drive circuitry and compressor, ensuring extremely low failure rates and low PPM.
