Additional Special Functions

A) The output of 3rd wire Signal-Rotation Detector Function:Suffix basic part number with "-RD" for Rotation Detector Function (DC FANS ONLY)

Lock Sensor (locked rotor alarm signal)
Lock sensors are used to detect if the fan motor is in operation or stopped.

B) The output of 3rd wire Signal-Frequency Generator Function:
Suffix basic part number with "-FG" for Frequency Generator Function (DC FANS ONLY)


Pulse Sensor (2 pulse per revolution signal) / Tachometer output


Pulse sensors are are used for detecting the rotational speed of the fan motor. If fan is locked on VH, signal stays locked. If fan is locked on VL, signal stays at VL for a few hundred MS, then moves to VH.Vcc: rated voltage

C)Temperature Control
Suffix basic part number with "-T" for Temperature for operating environments where noise andtemperature are a consideration. When the built in thermistor detects a drop in ambienttemperature, the fan rpm will decrease resulting in a lower noise level and airflow rate.Conversely, as the thermistor detects a rise in temperature, the noise level will increase relativeto the rise in the fan's rpm's until the targeted temperature has been attained. (DC FANS ONLY)

D) Dust and Water Splash Resistant as per IEC IP-5.4 Suffix basic part number with "-54" for DustResistant/Water Splash Resistant. This unit is protected against splashing water (water sprayingat all angles @ 10 liters/min @ a gage pressure of 80-100kN/m2 for 5 minutes.


Dust and Water Jet Resistant as  IEC IP-5.5 Suffix basic part number with "-55" for DustResistant/Water Jet Resistant. This unit is protected against water jets projected at all anglesthrough a 6.3mm nozzle at a flow rate of 12.5 liters/min at a gage pressure of 30kN/m2 for 3minutes from a distance of 3 meters.

E) Current limit protection / Auto restart protection
When the fan motor is locked, the device will cut off the drive current within two to six seconds and restart automatically after a few seconds. If the lock situation is continued the device will work as cut off >restart>cut off> restart>... repeatedly till the lock is released.

F)Speed control by PWM Signal
A speed control lead can be provided that will accept a PWM signal from the customer circuit to vary the speed of the fan. The change in speed is linear by changing the Duty-Cycle of the PWM. PWM signal types are standardized as following;Open collector type and pull-up voltage is changed by maximum operating voltage and sink currrent by consuming current.

*PWM signal function design is decided by customer.

G) Parylene Coatings

Specialty of Parylene Coating
Because the Parylene coating will be processed in vacuum chamber, and has been applied by Gaseous Precipitation, thus its protective coating quality is much greater than applied by dipping or spraying, and has no unevenness coating, no cracks of gaps. This Parylene coating has very good resistance to both acid and alkali, and has passed by US Military Standard MIL-I-46058C.
