IV. CHARACTERISTIC DEFINITION
The following is a general description of certain tests that are performed on
representative SUNON fans in order to determine the specifications of the fan.
Nothing in this document is intended to suggest that these tests are performed on
every model of SUNON fan. Moreover, the descriptions that follow each test are
meant only to provide a general explanation of each test. If you would like a more
detailed explanation as to any test identified in this Section, SUNON can provide
such an explanation upon request.
1. ACOUSTICAL NOISE
Measured in a semi-anechoic chamber with background noise level below 15dB(A).
1 METER FROM MICROPHONE TO FAN INTAKE
The fan is running in free air under shaft horizontal condition with the microphone at
distance of one meter from the fan intake.
2. INPUT POWER
Measured after continuous 10 minute operation at rated voltage in clean air
( STATIC PRESSURE=0), and at ambient temperature of 25 degrees C under shaft
horizontal condition.
3. RATED CURRENT
Measured after continuous 10 minute operation at rated voltage in clean air
( STATIC PRESSURE=0), and at ambient temperature of 25 degrees C under shaft
horizontal condition.
