4. RATED SPEED
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.
5. STARTING VOLTAGE
Measured the voltage which enables to start the fan in the clean air (static pressure = 0 )
by switching on at the voltage under shaft horizontal condition. It is not at continuously
increasing voltage adjustment.
6. LOCKED ROTOR CURRENT
Measured immediately after the fan blade is locked.
7. AIR FLOW AND STATIC PRESSURE
The performance specification of air flow and static pressure shown in this specification for
approval is measured using the exhaust method. A double chamber is used in accordance
with AMCA 210 standard or DIN 24163 specification . The values are recorded when the
fan speed has stabilized at rated voltage.
8. INSULATION RESISTANCE
1. PLASTIC HOUSING:
(1) Measured between internal stator and lead wire(+).
(2) Measured between housing and lead wire(+).
2. ALUMINIUM HOUSING:
Measured between internal stator and lead wire(+).
9. DIELECTRIC STRENGTH
Measure between housing and lead wire(+).
