Parameters and functions of San ace cooling fan

Parameters and functions of San ace cooling fan The performance parameters of San ace cooling fans are various. When we buy cooling fans, we need to ask the seller about the specific models and parameters. Now let's have a look 1. Main parameters of the cooling fan: size, voltage, current, power, air volume, static pressure, noise, service life, bearing system (double ball bearing, hydraulic bearing, oil bearing), which are directly related to the cooling performance, energy saving, long service life, mute, etc. of the cooling fan. 2. Certification of cooling fan: UL, CSA, en, CE, ROHS, CCC and other certifications (you can choose what certification you need according to your equipment positioning) 3. Functions of the cooling fan: soft start function, locking protection function, FG speed measurement function, RD alarm function, overvoltage protection, temperature control function, PWM speed regulation function, waterproof function (waterproof function can be selected in outdoor, humid, dusty and other places under harsh environment, and the waterproof grade gradually increases from IP54 to IP68). These functions are customizable. 4. Cooling fan power line: the wiring line sequence, line length, terminals, etc. shall be clearly understood and combined with their own equipment. Capital Technology Co., Limited is the chief agent of SANYO DENKI, one of the leading enterprises of the cooling fan industry. We are a factory who also have our own independent brand CAPITAL product series. The main products are cooling fan, DC/AC fan, radiator, filter, reactor etc. We can provide customer with the most professional and perfect technical support, welcome to contact me at anytime at rainlee@szcpt.com.

How to select the function of San ace cooling fan

How to select the function of San ace cooling fan With the demand of environmental protection, energy conservation and convenience, the special functions of cooling fans have also been born. Next, let's take a look at the special functions of San ace Sanyo cooling fans. Self starting function: when the cooling fan is locked and cannot run, its working current will be cut off automatically, and the cooling fan operates under the state of low current, so as to protect the cooling fan from burning due to high current. At certain intervals, the cooling fan will automatically output a signal to start the fan. When the fan is not locked, the cooling fan will be restarted and run normally. PWM speed regulation function: the PWM function can use frequency and high and low voltage levels to control the speed of the cooling fan. The fan speed can be linearly controlled by adjusting the "duty cycle", which can achieve the effect of energy saving and noise reduction. FG speed measurement function: this function outputs a square wave signal. The function mainly outputs a square wave signal from the inside of the fan, and the frequency of the signal represents the speed of the fan, that is, the speed of the cooling fan can be read by reading the FG signal. Rd alarm function: This is an open collector function, which is the same hardware function as the FG mentioned above. When the cooling fan is running, the signal pin outputs a low level, and when the rotor is blocked, it outputs a high level. Whether the cooling fan is in normal operation or locked state can be determined by monitoring the RD signal level. Temperature control function: when this function is applied, the speed of the cooling fan is controlled by the temperature, and different temperatures can correspond to different speeds. The ambient temperature of the fan is monitored through the thermistor, and the speed of the cooling fan is appropriately adjusted according to the temperature, so as to save energy and reduce noise. Waterproof grade: the waterproof and dustproof grade of the cooling fan can be customized according to user requirements. San ace Sanyo can achieve the highest waterproof grade of ip68 Capital Technology Co., Limited is the chief agent of SANYO DENKI, one of the leading enterprises of the cooling fan industry. We are a factory who also have our own independent brand CAPITAL product series. The main products are cooling fan, DC/AC fan, radiator, filter, reactor etc. We can provide customer with the most professional and perfect technical support, welcome to contact me at anytime at rainlee@szcpt.com.
