Replacement Inverter for 120 mm Fans

This inverter module is built for 120 by 120 by 38 mm cooling fans carrying the TA450DC and B34978-55 designations. It accepts a 24 V supply and draws 0.41 A during operation. The unit suits technicians maintaining server or industrial enclosures that use this specific frame size and voltage.

Direct Swap Restores Original Airflow

Installing the matching inverter returns the fan to its factory electrical characteristics without rewiring or adapter cables. The correct voltage and current rating prevent overload on the power distribution board. Builders using different frame depths, voltage rails or current profiles should select a module specified for those parameters.

Questions about this item

How often should the 24 V 0.41 A inverter fan be inspected or replaced in continuous operation?

Plan a visual check every six months; replace the unit if bearing noise appears or airflow drops below the 120 mm × 120 mm × 38 mm frame rating.

What thermal limit is reached first when the TA450DC B34978-55 runs at full load for long periods?

The 24 V 0.41 A motor hits its maximum safe winding temperature before the 12038 frame can dissipate additional heat.
