How to choose a fan? What are the performance characteristics of SanAce DC fans?
Do you know how to choose a fan? What are the advantages of fans with different performance characteristics? Below, the editor will show you.
All design engineers of motors and electronic products that require the use of fans for heat dissipation must determine the required air volume for a specific system, which depends on understanding the system's power consumption and whether it can remove enough heat to prevent overheating. The fact shows that the service life of the system will be reduced due to insufficient cooling system, so design engineers should also understand that the sales volume and price of the system may decrease because the service life of the system does not meet the expectations of users.
To select the correct ventilation components, please consider the following objectives:
1. The best air flow efficiency
2. The smallest suitable size
3. The minimum noise
4. Minimum power consumption
5. Maximum reliability and service life
6. Reasonable total cost
Below, we will introduce a SanAce DC fan to you.
SanAce DC fan is a direct current fan under the Japanese SanAce brand. This type of cooling fan has the characteristic of multifunctional integration and is widely used in our daily production and life. Today, SanAce fan agent manufacturer will introduce in detail what functions SanAce DC fans have.
1. FG (Frequency Generator) signal/speed signal output
The square wave output we often refer to is mainly used to output a square wave signal from inside the fan, and the frequency of the signal represents the speed of the fan. Conventional four pole fan: speed=FG frequency * 30. That is to say, the fan speed can be read by reading the FG signal.
2. Temperature control function
By monitoring the ambient temperature of the fan operation through a thermistor, the fan speed can be adjusted appropriately according to the temperature, achieving the goal of energy conservation and noise reduction.
3. RD (Ratio Detector) function
The RD function is also commonly referred to as the Alarm signal. When the fan is running, RD is at a low level, and when the fan is locked, RD is at a high level. By monitoring the high and low levels of the RD signal, it is determined whether the fan is operating normally or in a locked state.
4. Auto Restart
When the fan is locked, the working current of the fan will be automatically cut off, and the fan will work in a low current state, thus protecting the fan from burning out due to high current; Another function of Auto Restart is that the fan automatically outputs a signal to start the fan at regular intervals. When the fan is not in a locked state, it will be restarted and run normally.
5. PMW (Pulse Width Modulation) speed regulation function
The so-called PWM refers to pulse width modulation. It refers to the frequency (period) of the pulse signal being constant, and changing the conduction period and cutoff period of the pulse signal to change the speed of the fan, achieving the purpose of energy saving and noise reduction.
6. Voltage signal speed regulation
Input a variable voltage signal to change the fan speed, achieving energy-saving and noise reduction goals.
7. Special Features
The product can be customized according to customers' special requirements for functions such as waterproof, dustproof, RD inversion, etc.
