Ec Centrifugal Fans With Ventilating Units Pa66 Fresh Air System 225mm
If two motors are producing the same output but one has a greater power input then you can be sure that the surplus energy is being dissipated as heat. If an application is designed to remove heat then it will have to do extra work just to remove the heat produced by the fan motor itself, so EC fans will improve the efficiency of the whole system
· EC motor features reverse polarity protection, locked rotor protection and soft start.
· No additional protection such as contactors are required.
· Can be pre-configured to suit specific sensors and applications, and are supplied standard with 0-10V control input.
· A full range of sensors are available including differential pressure, humidity, temperature, air velocity and pollutant.
· Can be run as an independent ventilation source or integrated into most building management systems.
Constant torque ,constant speed and constant airflow of EC fan can be fulfilled via180,sineSVPWM(Space Vector PWM)to meet customer needs
Intelligent EC fan can support users to realize centralized operation control by 485 bus and monitor as many as 255 fans
EC fan has comprehensive protection function, such as phase failure, overvoltage, undervoltage, locked-rotor, over current and temperature protection
