Technical Solution

The overall controller scheme adopts a topology structure of three-phase rectification, power inverter, and signal control.

The three-phase power supply is rectified by diodes to become a stable DC voltage.

The inverter part formed by six power switching devices is connected with the motor winding.

Some controller parameters

Input voltage：3~ 380-480VAC

Input frequency：50/60Hz

Input power：5.2kW

Input current：8A

Input current：0.95

1, RS485 hardware interface: baud rate 19200，8E1.

2, Modbus RTU：A globally recognized free standard protocol.

3, Maximum number of fans: up to 247 units.

PC software compatibility: The 485 converter can be easily connected to the configuration software on the PC to reconfigure the fan’s parameters.

Remote online monitoring: Through a suitable converter, the real-time operation status of the fan can be remotely monitored.
