Fans PMD2408PMB2-A DC24V 7.2W 80x80x38mm case fan

SKU CH-TDA5-4YT25

A 24 V DC axial fan measuring 80 × 80 × 38 mm delivers 143 m³/h airflow at 5700 rpm with a 55.2 dB noise level and ball-bearing construction

  • 24 V DC supply suits industrial 24 V systems
  • 143 m³/h airflow handles demanding heat loads
  • 5700 rpm ball-bearing motor sustains continuous operation
  • 2 dB noise level fits noise-aware deployments
  • 80 × 80 × 38 mm frame drops into standard 80 mm mounts

24 V DC axial fan for inverter cooling

The SUNON PMD2408PMB2-A is a 24 V DC axial fan built for inverter and industrial cooling duties. Its 80 mm square frame and 38 mm depth suit tight equipment bays where forced-air exchange is required. The unit targets engineers and integrators who need reliable airflow in 24 V systems.

Ball bearing sustains 5700 rpm under continuous load

A ball bearing supports the 5700 rpm operating speed for long-term operation. At full load the fan draws 400 mA and delivers 143 m³/h of airflow while producing 55.2 dB of noise. Power consumption is rated at 7.2 W with a maximum of 9.6 W, so thermal performance remains steady during extended runs.

Simple 80 mm mounting with two-wire DC supply

The 80 x 80 mm footprint matches standard 8038 mounting patterns, allowing direct replacement in existing cut-outs. Only a 24 V DC supply and two wires are needed for installation. Builders using other voltage rails or expecting PWM control will find this model incompatible.

Questions about this item

How loud is the 5700 rpm fan when it runs continuously at 24 V?

The fan produces 55.2 dB of noise at full speed, which is typical for a 80 × 80 × 38 mm ball-bearing unit moving 143 m³/h.

What power source and connector does the 24 V DC fan require?

It needs a 24 V DC supply capable of at least 400 mA (9.6 W) and a matching two-pin or three-pin DC fan header.

Will the 80 mm frame fit the same mounting holes as my older 8038-size fans?

Yes, the 80 × 80 mm square footprint and 38 mm depth match the standard 8038 form factor, so existing screw holes line up.
