Description
The SUNON KDE1209PTVX axial fan is designed for forced cooling of electronics in limited space, typically for coolers, equipment cabinets and industrial applications. Thanks to the 4-wire connection with PWM control, it allows for smooth speed regulation and at the same time provides a tachometer signal for monitoring operation.

Package contents
Fan SUNON KDE1209PTVX
Why choose this product?
Clearly defined electrical parameters for 12 V DC power supply
4pin PWM interface for speed control and integration into system supervision
Compact size of 92 × 92 × 25 mm for wide compatibility in electronic devices
Flow and static pressure combination suitable even for restrictive coolers
Installation and operating instructions
Verify mechanical compatibility (dimensions 92 × 92 × 25 mm) and airflow orientation according to the arrows on the fan frame.
Supply only with 12 V DC and size the power supply at least for the specified current with a margin.
For PWM control, use a 4-pin connector; when connecting to another system, verify the pinout and control signal levels.
Ensure free air flow and minimize obstacles (grilles, filters) with respect to the required flow rate.
Safety notice
The fan is a rotating device; protect fingers and wiring from contact with the impeller during operation.
Disconnect power before installation or servicing.
Do not exceed the rated voltage of 12 V DC; improper power supply may result in fan damage or excessive heating.
