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.

Questions about this item

Does the ORIX MU1225S-81N-F1 include mounting screws or a power cable?

The fan is supplied as a fan-only unit with a 2-pin connector. Mounting screws and any extension cables are not included and must be sourced separately.

Should I select the 50 Hz or 60 Hz rating for my UPS inverter?

The fan operates at both 50 Hz and 60 Hz, drawing 11 W at 50 Hz and 9.5 W at 60 Hz. Choose the rating that matches your local mains frequency or inverter output.

What airflow can I expect from the 120 mm AC24V fan inside a server chassis?

The 120×25 mm frame moves air at the rated 11 W / 9.5 W power levels. Actual airflow depends on chassis restriction and voltage stability in your specific installation.
