Compact 40 mm case fan runs on 24 V at 0.08 A and includes an alarm driver

  • Alarm driver alerts you to fan failure
  • 24 V operation suits industrial and server chassis
  • Low 0.08 A draw reduces power load
  • Compact 4020 form factor fits tight spaces

Compact 24V case fan with alarm

This 4020 form-factor fan runs on a 24 V supply and draws 0.08 A. The integrated alarm driver signals a fault when the rotor stalls or speed drops below threshold. It suits tight chassis, industrial enclosures or embedded boards that need monitored airflow in a small footprint. Builders who require variable-speed PWM control or a larger frame will need a different model.

Thermals, noise and power

At 0.08 A the unit consumes roughly 2 W, so heat added to the loop is minimal. The alarm circuit adds no audible noise during normal operation; only a stall triggers the signal. With no RPM or decibel figures supplied, exact acoustic and thermal performance cannot be quantified.

Questions about this item

How do I connect the 24 V alarm driver wires during installation?

Match the 24 V supply to the red lead, ground to black, and the alarm signal to the third wire; the common mistake is reversing power and ground which disables the alarm.

Which component typically fails first on the 1608kl-05w-b39 4020 fan?

The sleeve bearing wears after continuous 24 V operation; when the .08 A draw rises or the alarm sounds, replace the whole 4 cm unit.
