OEM Industries MMF-09D24TS MMB 9CM 24V 3 Pin Fan

Industrial 9 cm 24 V fan for PLC cabinets

This 9 cm axial fan is built for 24 V DC control cabinets and inverter drives such as YASKAWA and ABB units. It draws 0.22 A through a three-pin connector and uses a dual ball bearing for continuous duty. The frame measures 90 by 25 mm and carries the Melco MMF-09D24TS MMB part number.

Three-pin 24 V interface limits speed control

The three-wire connection supplies power, ground and a tachometer signal but no PWM input. Voltage regulation is the only way to vary speed, so the host controller must be able to adjust the 24 V rail or accept fixed-speed operation. The 0.22 A draw is modest, yet the supply must deliver a stable 24 V under load.

Verify 24 V rail and three-pin header before fitting

Check that your PLC or inverter chassis provides a 24 V DC header with the same three-pin pitch and polarity. Confirm the 90 mm mounting pattern matches the cut-out in your enclosure. The fan has no LED or thermal probe, so external monitoring must rely on the tachometer wire alone.
