Fgi Fd300 380V~440V Low Voltage VFD 50Hz/60Hz Inverter Variable Frequency Drive Pump Fan HVAC Energy Efficiency Optimization Industrial Flow Control System

Fgi Fd300 380V~440V Low Voltage VFD 50Hz/60Hz Inverter Variable Frequency Drive Pump Fan HVAC Energy Efficiency Optimization Industrial Flow Control System. Adopting SVPWM, SVC and FVC algorithms, FD300 achieves dynamic response within 20ms. It supports PMSM and direct drive motors, with speed control range up to 1:1000 in FVC mode. Stable operation as low as 0.01Hz. It provides 150% starting torque at 0.25Hz (SVC) with low torque ripple, delivering smooth operation for heavy-load and high-precision scenarios. Multiple braking modes realize fast and safe stop for large inertia loads. The flying start function enables smooth restart of rotating motors.
