Industrial 24 V Case Fan

The SXDOOL MMF-12D24DS-RN8 is a 120 mm square frame fan built for 24 V DC systems. It targets technicians maintaining PLC cabinets, servo drives or similar industrial equipment where the original Melco unit has failed. The two-pin connector and fixed voltage make it unsuitable for standard PC motherboard headers or PWM speed control.

Two-Pin Fixed Voltage Limit

The fan draws 0.36 A at 24 V for roughly 8.6 W of power. Because the connector carries only power and ground, the motor runs at full speed whenever voltage is present. There is no tachometer signal for monitoring and no PWM input for variable speed, so airflow cannot be adjusted by the host device.

Straightforward Swap With Polarity Care

Installation consists of unplugging the old fan and connecting the two pins to the same 24 V supply. The only common error is reversing the wires, which will prevent the ball-bearing motor from starting. The 38 mm thickness matches the original housing, but installers should verify that the mounting holes align with their specific chassis before securing the 250 g unit.

Questions about this item

Should I choose the 24 V version or a 12 V alternative for my inverter?

This model runs on 24 V and draws 0.36 A, so select it only if your power supply provides 24 V DC.

What does the 8.6 W rating mean once the fan is installed in a PLC cabinet?

At 24 V the fan consumes 8.6 W, giving a steady airflow for cooling ABB or Yaskawa drives without overloading the 24 V rail.

How does the two-pin connector limit speed control options?

The 2-pin power connector supplies fixed 24 V only, so the fan runs at constant speed with no PWM or voltage regulation.
