OEM Industries MU1225S-81N-F1 120mm 2-pin AC24V fan

120 mm AC24V fan for UPS and inverter cooling

This 120 mm square fan runs on 24 V AC power and draws 11 W at 50 Hz or 9.5 W at 60 Hz. It is built for industrial UPS units, inverter enclosures and similar equipment that require forced-air cooling from an AC mains supply. The two-pin connector provides a simple power interface without PWM or speed reporting.

Check your power source

Verify that the equipment supplies 24 V AC at either 50 Hz or 60 Hz; the fan will not operate on DC voltages or other AC levels. Confirm the chassis has 120 mm mounting centres with a 25 mm depth clearance and that the two-pin plug matches the existing header or can be adapted safely. The unit has no LED lighting and no speed-control wire.

Black frame with 25 mm thickness fits standard 120

The all-black plastic housing measures 120 mm by 120 mm by 25 mm, matching the common 12025 form factor used in many power enclosures. Two mounting holes accept standard screws for secure fixing in vibration-prone environments. The bare two-pin lead allows direct wiring or connector replacement without proprietary locking tabs.
