Introductions
Every model undergoes rigorous aerodynamic analysis and anechoic chamber test to achieve minimum noise under high airflow and air pressure conditions.
High precision maintenance-free ball bearing system provides superb reliability.
Frame and fan blade meet UL 94V-0 flammability rating.
Every model features locked rotor protection and polarity protection, and offers optional frequency generator or rotation detector function.
All DC fans are 100% balanced to guarantee low vibration and excellent durability.
Automatic multi-axes winding, surface-mount machine and highly automated assembly lines enable mass production and consistent quality.
UL, CSA, VDE approved.

Noise Measurement
NOISE IS MEASURED AT RATED VOLTAGE IN ANECHOIC CHAMBER IN FREE AIR WITH LARSON DAVIS AND WITH MICROPHONE AT A DISTANCE OF ONE METER FROM THE FAN INTAKE. REFER TO ANSI-S12.10 AS SHOWN BELOW:
SEMI ANECHOIC CHAMBER LEVEL
Semi Anechoic Chamber for ISO 7779
Residual Background Noise Level: 15.0 dB (A)
Lowest Cutoff Frequency (Fco): 100 Hz
Frequency Generator O/P: (F00)
Frequency generator function is activated by an internal IC for customer's application.
Electrical schematic:
• CUSTOMER'S CIRCUIT
Vcc = From +5 To +28 VDC (Generally using +12 or +24 VDC)
Ic = 5 mAmax.
R = V/I (Output "R" value calculation)
• SUPPLY A WAVEFORM:
N=R.P.M. (Rotation speed will be different for various models
L/M/H/HH/VH/SH)
TS=60/N (Sec)
* Voltage level after blade locked
* 4 POLES OR 8 POLES
• OUTPUT LEVEL:
High = Vcc 10%
Low = 0~0.5V
Ic = 5 mAmax.
• APPLICATION:
• FUNCTIONS:
By means of waveform & customer's design, schematic can reach alarm function, either in the form of buzzing or LED flashing.
Adjust rotation speed.
When power supply output voltage level decreases, it will result in the lowering of fan rotation speed. The irregular situation will be controlled by using F.G. O/P through P/S circuit to increase the output voltage and result in a stable rotation speed.
Rotation Detector O/P (R00)
Rotation detector function is activated by an internal IC for customer's application.
• Electrical schematic:
CUSTOMER'S CIRCUIT
Vcc = From +5 To +28 VDC (Generally use +12 or +24 VDC)
Ic = 5 mAmax.
R = V/I (Output "R" value calculation)
• SUPPLY A WAVEFORM:
OUTPUT LEVEL:
High = Vcc 10%
Low = 0~0.5V
Ic = 5 mAmax.
• APPLICATION:
• FUNCTIONS:
By means of waveform & customer's design, schematic can reach alarm function: either in the form of buzzing or LED flashing.
