  • 24 W rated output delivers strong airflow for dense enclosures

24 V DC 12038 Inverter Fan

This 120 mm square fan runs on 24 V DC and draws 1 A for 24 W of cooling power. The 38 mm thick frame suits inverter enclosures or industrial chassis that require high static pressure. It is aimed at system integrators and maintenance engineers who need reliable airflow in 24 V environments.

Four-wire PWM installation notes

The four-wire lead provides power, ground, tachometer feedback and PWM speed control. Connect the PWM wire to a compatible header; leaving it floating can cause the fan to run at full speed or stop entirely. Verify pin-out against the equipment manual before powering up to avoid reversed polarity damage.

Questions about this item

How can I verify the 24 V DC fan is running at the rated 1 A current after installation?

Measure the supply current with a multimeter while the fan is powered; a reading close to 1 A at 24 V confirms the 24 W draw.

What comes in the box and what extra parts are needed to connect the four-wire lead?

The package contains the 120 × 120 × 38 mm fan only; a compatible 4-pin PWM header or separate 24 V power adapter must be sourced separately.
