| The FOC solution brings low noise and low vibration. Virous control modes of constant speed, constant torque, constant power and constant flow. Diversity interface of 0-10V, PWM, TTL-UART, RS485, Modbus, CAN. And customized protocols against clients' requirements are available. Compatible with various fan loads, mature closed-loop start technology both downwind or upwind, harmonic compensation technology, automatic air volume calibration, carrier frequency jitter technology. SVPWM over-modulation technology improves the max running speed of the motor, reduce the device's loss and improve the efficiency. Perfect protection mechanism: AC input overvoltage and undervoltage, DC bus overvoltage and undervoltage, SW and HW overcurrent, phase loss, step loss, overheating, communication failure, etc. Several power limitation strategies through input current, voltage, phase current, temperature or others. |
