Fans AD0424MB-C50 24V 0.07A 4020 dual ball power inverter

SKU CH-HV34-HJC3K

24 V dual-ball-bearing inverter fan measuring 40 × 40 × 20 mm draws 0.70 A for server power-protection cooling

  • Reliable dual-ball bearings extend service life
  • 24 V 0.07 A draws minimal power
  • Compact 4020 footprint fits tight enclosures
  • New original ADDA build ensures quality
  • Suited for medical, rail and industrial cooling

Compact 24 V inverter cooling fan

The ADDA AD0424MB-C50 is a 40 mm square, 20 mm thick axial fan that runs on 24 V DC and draws 0.07 A. It uses dual ball bearings for continuous operation in industrial and embedded equipment.

Suited for tight chassis needing reliable airflow

Engineers fitting medical devices, rail vehicle controllers or industrial cleaning units will match the voltage and current envelope. Builds that require a different voltage, higher airflow or a larger frame should select another model.

Dual ball bearings extend service interval

The bearing choice reduces wear in vibration-prone environments such as drive cooling or new-energy vehicle systems. No extra mounting hardware, connectors or control software are included with the fan alone.

Questions about this item

What 24 V DC supply and 40 mm × 40 mm mounting cut-out must already be in the chassis for the AD0424MB-C50 to install?

The fan needs a 24 V DC source capable of 0.70 A and a square 40 mm × 40 mm opening with 20 mm depth clearance for the 4020 frame.

Will the dual-ball bearing AD0424MB-C50 share a 24 V rail with legacy 110 VDC fans such as the 7210N-181 without extra regulation?

No — the AD0424MB-C50 requires 24 V DC while the 7210N-181 runs on 110 VDC, so they need separate voltage rails or a step-down converter.

How do I confirm the AD0424MB-C50 is spinning at the correct speed after power-up?

Measure the supply current at the 24 V input; a steady 0.70 A draw indicates the dual-ball motor is running at its rated operating point.
