Compact 24 V inverter fan

The Ruth's sister 4010 measures 40 by 40 by 10 mm and runs on 24 V DC at 0.05 A. Its three-wire connection suits inverter cooling and similar low-power internal tasks. New condition means the unit has not been previously installed.

Three-wire speed signal included

The third wire carries a tachometer signal so the host system can monitor fan speed. No extra connectors, mounting hardware or control software are supplied with the cable.

Questions about this item

Will the 3-wire connector need replacing during the fan's life?

The 3-wire lead is fixed to the motor; if the connector fails the entire 4010 unit must be swapped.

What limits continuous running of the 24 V 0.05 A motor first?

The sleeve-bearing rotor wears gradually, so bearing noise and eventual seizure set the practical runtime ceiling.
