Product Q&A

Q:What is the input voltage range?

320~485Vac (3-phase), rated 380~440V

Q:Does it support both AC motors?

Yes, supports both asynchronous and synchronous motors.

Q:Can the inverter operate at very low frequencies under load?

Yes. The FD200 series can maintain stable heavy-load operation at frequencies as low as 0.01Hz, ensuring smooth low-speed performance with minimal torque ripple.

Q:Is it sensorless vector control?

Yes, advanced sensorless vector control for high torque and stability.

Q:Can it handle sudden power loss?

Yes, built-in ride-through function keeps running during short power dips.
