SKU CH-DYH6-0DM3V MPN 4314/17TMotor

24 V DC axial fan with speed alarm and optional NTC sensor, 4.8 W at 2800 RPM in a 120×120×38 mm PBT housing rated for 65,000 hours L10 life

  • Robust PBT housing and PA impeller resist vibration
  • 8 W at 24 V draws only 0.2 A current
  • 2800 RPM airflow cools dense 120 × 120 × 38 mm enclosures
  • Speed alarm signals low-signal fault when RPM target missed
  • 65000-hour L10 ball-bearing life reduces replacement cycles

Compact 120 mm DC axial fan

This 120 x 120 x 38 mm axial fan from the 4314 series runs on 24 V DC and draws 0.2 A at 4.8 W. It spins at 2800 RPM using a maintenance-free ball bearing system housed in glass-reinforced PBT with a glass-reinforced PA impeller. An integrated speed alarm emits a continuous high signal during normal operation and a low signal if the set speed is not reached. Rated life expectancy reaches 65000 hours at L10.

Suited for fixed-speed 24 V cooling in enclosures

The fan suits builders who need a robust, fixed-speed 24 V DC axial fan with integrated speed monitoring for electrical cabinets or enclosures. Its clockwise exhaust orientation and IP20 rating fit standard panel-mount cutouts. Buyers who require PWM speed control, a different operating voltage, or a thinner frame should consider other options.

Single-rail 24 V power requirement

Operation requires a stable 24 V DC supply capable of delivering at least 0.2 A. The two-wire plus alarm connector does not support PWM or voltage regulation, so the fan always runs at full 2800 RPM when powered.

Questions about this item

Does this fan need a 24 V DC power source to run?

Yes, it requires a 24 V DC supply and draws 0.2 A for its 4.8 W rating.

Can I use the speed alarm output with a motherboard fan header that expects a tachometer signal?

The alarm outputs a continuous high signal at normal speed and drops low if the fan falls below the set threshold, so it can serve as a speed monitor.

How do I confirm the fan is spinning at the rated 2800 RPM once installed?

The built-in alarm signal stays high while the fan runs at the correct speed; a low signal means the target RPM is not being reached.
