6-12.特性定义Characteristics definition: |
||
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 at rated voltage.
|
||
Starting voltage is the least voltage that enables to start the fan by sudden power on.
|
||
7.保护功能 Protection:
|
||
7-1.风扇旋转锁定测试:将风扇通电锁死测试至少72小时,当锁定解除之后均仍然正常运转 Lock test: Locked 200 units for at least 72 hours. Fans work in normally after locked released.
|
||
7-2.反向电压测试:以12V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 200pcs for reversal voltage test at 12V for 5 minutes and all remain still. Fans work normally after corrected voltage.
|
转速检测RPM detection :
T=T1+T2+T3+T4
<说明>
Output waveform: square wave
When the voltage value is higher (Voltage Y) the output waveform is higher.
When the fan is shutdown then output waveform is a horizontal line
The cyclic distance is longer then the RPM is slower.
RPM formula as follows:
RPM= 60000
X(ns)
<例>Example
X=15ns
Ls=1000ns
Lmin=60000ns
RPM= 60000 =4000
12.注意事项(Notes):
12-1.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 will not guarantee the product if the application of our products are exceeded the limitation which is specified on this specification.
12-2.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.
12-3 请勿触压叶片以及电源线缭绕风扇或用力拉扯电源线,如此轴心与电源线会被损坏
Please do not touch the impeller with the pressure and never bring the fan with lead wire.The bearing and lead wire may be danaged.
12-4. 本产品不保证因粉尘,小虫进入,而影响寿命与不良品产生
No guarantee on the products against the safety problem or failure caused by powder dust,drop of wate or insect
12-5.如有任何资料及文件与此文件资料不同,将以此分资料为主要参考
If there is any data or related documentation different from this data sheet. This data sheet is the principle reference
12-6.请勿在可燃性气体下任何有害环境中使用
Please do not use the fan in the environment of corrosive gas or liquid or any detrimental gas
12-7.请于六个月内使用,否则风扇存放在很高温或很低温,湿度很高或室温中风扇于六个月后会有漏电流产生
Please do not store the fan in the environment of high/low temperature, high humidity or detrimental gas.Please store within six months ,every six months, shall be a leakage of electric current ot the fan,even though the fan is stored in room temperature
12-8.当风扇于运转中,请勿企图将风扇锁死特别长的时间,如此,会因连续停止不转,产生高热而烧毁风扇
While the fan is in operation ,please do not lock the fan intentionally for a long periods of time,since the continuous stoppage will result in overheat and thus burnt out the fan
12-9.组装风扇时,请特别注意,因共振或振动产生的噪音
During the installation of the fan, please pay substantial attention to possible notice caused by resonance
12-10.当搬运或作业中,风扇如从
It is very important to notify that avoid to drop from
12-11. 锁外壳之螺丝扭力不得超4Kgf.
The torque of the screw which locked the frame should not exceed 4 Kgf.
