Pa66 220mm EC Centrifugal Fans With Filtering Ffu Air Source Heat Pumps
EC Motor – Principle
With an EC motor the electronic circuitry stands in lieu of the
traditional mechanical commutation meaning the right amount is
being supplied in the right direction at exactly the right time
providing precise motor control
Type | Nominal voltage (VAC) | Frequency (HZ) | Speed | Power imput (w) | Current draw (A) | Sound pressure (dB) | Perm.amb.temp |
LD220C-230D3-00 | 220 | 50/60 | 2600 | 75 | 0.6 | 68 | -25~+60 |
AC vs. EC
The available range of AC input EC fans is expanding all of the time. There are axial and centrifugal fans, forward curved and backward curved, single inlet and double inlet, single phase and three phase and they are often directly interchangeable with their AC equivalents. EC offers the OEM more than just energy-efficiency. It is an opportunity to bring new technology and functionality to their products. With ever-increasing demand for energy efficient systems, when it comes to fan based products, there’s no reason for manufacturers not to have any in their portfolio.
Variable speed control of EC fan can be realized / achievedvia 0-10V speed adjustment and/or external circuit impulse modulation
Constant torque ,constant speed and constant airflow of EC fan can be fulfilled via 180,sine SVPWM(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
FAQ
1.Can we buy a sample for testing?
Sure, you are welcomed to buy a sample before mass order.
2. if the fans doesn't work well, what shall I do ?
If happens within one year, we will take in charge of the maintenance, or send you a new machine freely.
