24 V three-line cooling fan

This 4020-size fan operates on a 24 V supply and draws 0.08 A for a rated power of 1.9 W. It is built for compact enclosures that need a low-current axial airflow solution. The three-wire lead provides speed monitoring for system supervision.

Buyers needing higher airflow or voltage

The 0.08 A current limit restricts this model to light cooling duties where space is at a premium. It will not suit applications that demand greater static pressure, a different supply voltage, or a larger frame size.

What does the 1.9 W rating mean for power draw in a 24 V system?

At 24 V the fan draws 0.08 A, which equals 1.9 W, so a 24 V supply only needs to budget that small amount for this cooler.

What does the three-line connection provide on this 4020 fan?

The three-line drive gives power, ground and a tachometer signal so the host can monitor actual fan speed.
