4020 24V Inverter Fan

This 4020 case fan runs on 24 volts and draws 0.08 amps, making it suitable for industrial enclosures and inverter cabinets that require a low-power cooling device. The mute alarm function provides a silent warning signal if the rotor stops, helping technicians detect a fault before components overheat.

Mute Alarm Feature

The integrated alarm output changes state when the fan fails, allowing a monitoring board or controller to log the event without audible noise in the rack. This removes the need for a separate tachometer wire or external sensor while still giving the system visibility of the fan health.

Questions about this item

Does the 4020 fan need periodic bearing lubrication or full replacement?

The 4020 fan uses sealed bearings that require no lubrication; replacement is only needed if the mute alarm signals a rotor stall or noise increases.

What limit appears first during continuous 24 V operation — thermal throttle or the .08 A current ceiling?

The .08 A current ceiling is the first hard limit; sustained 24 V draw cannot exceed it, so thermal protection never activates before the current limit.
