What is EC ?
We are one of EC fan manufacturers, we provide high quality forward curved EC centrifugal fan and backward curved EC centrifugal fan. Here I will introduce EC fan to you.
1.Variable speed control of EC fan can be realized 0~10v speed adjustment or external circuit impulse modulation.
2.Constant torque, constant speed and constant airflow of EC fan can be fulfilled via 180° SVPWM (Space vector PWM) to meet customers’ needs.
3.Intelligent EC fan can support users to realize centralized operation control by 485 bus and monitor as many as 255 fans.
4.EC fan has comprehensive protection function, such as phase failure, over voltage, under voltage, locked-rotor, over current and temperature protection.
