产品名称

DC  9238  FAN   PWM

产品规格

9238B   12V   0.718A   4500RPM

4-13. 特性定义 Characteristics

4-13-1.   额定电流 ＆ 额定转速 ＆ 额定操作功率，须在额定电压下；马达连续转５分钟达到规格下限，10

分钟达到正常值

Rated current, rated speed, and rated input power shall reach bottom line of specification after 5 minutes

Continuous rotation at rated voltage and reach standard specification after 10 minutes continuous voltage.

6-13-2.起动电压是指突然通电后能够使风扇起动之最低电压

Starting voltage is the least voltage that enables to start the fan by sudden power on

5．保护功能  Protection

5-1．后向电压测试：以电源电压作反向导电测试5分钟均不转动，再正向导电仍可正常转动

Reversal voltage test: We took 200Vpcs for reversal voltage test at power supply for 5 minutes and all remain still..Fans work normally after corrected voltage.

8.转速侦测  RPM detection

8-2．转速侦测说明

8-2-1．输出波形：方波

        Output waveform: square wave.

8-2-2．当电压值愈高（Voltage Y值），则输出波形愈高

       When the voltage value is higher (Voltage Y)then output waveform is higher

8-2-3．当风扇不转，则输出波形为一水平线。

      When the fan is shutdown then output waveform is a horizontal line

8-2-4．循环距离越长（Voltage Y值），则转速越慢

      The cyclic distance is longer then the RPM is slower.

8-2-5．转速计算公式如下：

       RPM formula as follows:

                           RPM=    60000

                                    X（ns）

             <例>Example

                 X=15

                 Ls=1000ns

                 Lmin=60000ns

                          RPM =    60000    =4000

                                     15

9．注意事项（Notes）

9-1．使用时请勿超出本规格所规定之极限，否则我们不保证此产品。

      We,JYD Co;LTD will not guarantee the products if the application of our products are exceeded the  

      Limitation which is specified on the specification.

9-2．倘若要变更此份文件的任何规格，请务必事先提出要求

      In case of changes of the specification specified on this document.  A  WRITTEN  NOTICE  IS

      REQUESTED IN ADVANCE。

9-3．请勿触压着叶片以及电源线缠绕着风扇或用力拉扯电源线，如此轴心与电源线将会被损坏

      please do not touch the impeller with the pressure and never bring the fan with lead wire .The bearing and

      lead wire may be damaged.

9-4．本产品不保证因粉尘、水滴、小虫进入，而影响寿命与不良产生

      No guarantee on the products against the safety problem or failure caused by powder dust, drop of water or
