Premium External Rotor EC Cooling Fan with 0-10V Stepless Control - Ultra-Efficient Axial Fan for Modern HVAC Systems

EC fan is essentially an intelligent fan that integrates drive, control, communication, and protection.

Intelligent control architecture:
Built in microprocessor (MCU) for real-time monitoring of speed, current, and temperature
Closed loop PID speed regulation, air volume control accuracy ± 3%, speed accuracy ± 1%
Support multi fan master-slave synchronization, with a single control signal to uniformly adjust the speed of array fans
Fault self diagnosis: Automatic triggering and reporting of overheating, overcurrent, locked rotor, and phase loss protection

Q: How much electricity does it save compared to AC axial fans?
The EC fan is equipped with a permanent magnet synchronous motor and electronic commutation drive, with an overall efficiency of 85-92%, which is 30-60% more energy-efficient than AC fans of the same level. In 24/7 operating scenarios such as data centers and building ventilation, the investment payback period is usually 1.5-2.5 years. Cooperating with the on-demand ventilation (DCV) strategy and operating at reduced speed during partial load periods, the actual energy-saving rate is higher.
Q: What speed regulation and control methods are supported?
Standard configuration includes 0-10V analog and PWM speed regulation, and optional MODBUS-RTU communication protocol can be used to connect to the building's automatic control DDC system. Built in speed (FG/TACH) and fault alarm (ALARM) signal feedback, supporting multi fan master-slave synchronous operation.
