Product Features:
SF730 series inverters have the following features:
1. Support mobile APP and Wi-Fi module to facilitate inverter debugging and monitoring.
2. Reliable operation withc full load at 50°C ambient temperature.
3. Integrated of special functions for rewinding and unwinding.
4. Support the high frequency output up to 3000Hz for driving high-speed motors.
5. Support 100kHz high-speed pulse input.
6. The built-in filter is close to level C3 , so the external interference is greatly reduced.
7. The metal substrate should adapt to the vibratory environ-ment to reduce the induced voltage of the motor.
