SKU CH-MB1D-4TMSY

A 92 mm square DC 24 V case fan with a three-wire white plug for Fuji inverter cooling

  • Reliable 24 V operation backed by original Mitsubishi engineering
  • Low 0.12 A draw reduces power load on inverter systems
  • Compact 92 x 92 x 25 mm frame fits tight enclosures
  • Three-wire white plug matches FRN37P11S-4CX Fuji inverter pinout
  • Brand-new authentic unit eliminates risk of counterfeit replacements

Direct replacement for Fuji inverter cooling

This 92 by 92 by 25 millimetre DC 24 volt case fan matches the MMF-09B24DH-RCB specification used in Fuji inverter units. The three wire white plug labelled FRN37P11S-4CX fits the original connector without adapters. It serves industrial drives medical equipment rail vehicles and other 24 volt cooling slots.

Upgrade from worn or noisy original units

When the factory fan develops bearing noise or reduced airflow the MMF-09B24DH-RCB restores the intended cooling profile. The 0.12 amp draw matches the inverter power budget so no electrical change is needed. Builders who need a different voltage or connector type should look elsewhere.

Steady airflow under continuous inverter duty

Designed for the constant load of inverter heat sinks the fan maintains stable speed without thermal throttling. The compact 25 millimetre frame fits tight ducting while the original plug ensures secure contact during vibration. Long term reliability depends on clean intake air and correct 24 volt supply.

Questions about this item

Will the 92 mm square frame and 25 mm depth fit my Fuji inverter enclosure?

The fan measures 92 by 92 by 25 mm, matching the standard mounting footprint used on Fuji inverter housings.

How do I connect the three-wire white plug labelled FRN37P11S-4CX without damaging the pins?

Align the keyed connector with the inverter header, press straight in until the latch clicks, and verify the 0.12 A draw at 24 V before securing the fan screws.

When should I plan to replace the bearings in this DC 24 V axial fan?

Expect continuous operation life of several years; schedule replacement when airflow drops noticeably or bearing noise increases beyond a low hum.
