at 25℃, 65%. The test result stated above is effective only for unique fan performance.
To avoid any unstable power, an “over 4.7 μF”
capacitor has definitely be connected to the fan externally whatever multiple fans are applied in parallel.
REMARKS
Y.S. Tech will not assume responsibility for the performance of the products if the application
condition falls outside the parameters stated forth in the specification.
A written request should be submitted to Y.S. Tech prior to approval if abnormality and deviation
from this specification is required.
Please be cautious when fan is being exercised or handled. Applying pressure to the impeller,
handling the fan by lead wire, or dropping the fans to the production platform is resulting in damage.
The correct polarity, Positive(+) and Negative(-), has to be clearly identified before connecting the
fan to the power. Be aware of the connection with reverse polarity may lead to damage since no
effective protection can be introduced against such errors.
The above conditions are examples of extreme application. However they are very important and
should receive top priority.
Y.S. TECH highly suggests to practics a test when fan work on a special application.
L10 of Life test is a deductive value under statistical power and it is different from product warranty.
All genernal specifications and quality values are tested under condition of free air and fan vertical set up.
With exception of suitability of some particular designs, any failure and problems regarding safety of
the product caused by the introduction of powder, droplets of water or encroachment of insert in the
hub are not guaranteed.
Except for the feature of the Lock Rotor Protection specifically stated, this feature is not applied to all
Y.S. Tech fans are not well sutted for corrosive environments. This includes liquids, gases, or matters.
fans. Y.S. Tech highly suggests not to stop the impellers of the working fans such interruption will
cause adverse effect.
Fans are to be stored in a dry/cool place. High levels of humidity are harmful to products.
Please be cautious when mounting the fan. Y.S. Tech is not responsible for any excess resonance,
vibration and subsequent noise caused by incorrect mounting of fans.
Take necessary precaution handling fans when in operation. Fingre guards are recommended to
All test environment are conducted under the condition of relative(ambient) temperature and humidity
