OEM Industries 109E1224H102 120x38mm 24V 0.25A CPU cooler

Square 120 mm fan for inverter cooling

This 120 mm square cooling fan from SANYO carries the model number 109E1224H102 and is supplied new in a grey finish. It is a fan-only unit without LED lighting, intended for integrators who need a replacement airflow component for industrial inverter or converter equipment. The 38 mm frame depth matches the standard 12038 footprint used in many legacy chassis.

24 V DC power requirement limits direct PC use

The motor is rated for 24 V at 0.25 A, so it cannot be powered from a typical 12 V motherboard header or standard PC fan controller without a separate voltage source. Wiring must accommodate the 24 V supply and the 0.25 A current draw, and the two-wire lead provides no PWM speed signal or tachometer feedback to the host system. Builders expecting 12 V operation or motherboard monitoring will find the electrical interface incompatible.

Verify voltage source

Confirm that your inverter or converter enclosure delivers a stable 24 V DC rail capable of at least 0.25 A and that the 120 mm by 38 mm square frame fits the existing cut-out and screw pattern. The lack of a PWM or sense wire means speed cannot be regulated or monitored by a PC motherboard, so the fan will run at full speed whenever power is applied. Ensure the mechanical depth and electrical connector suit the target equipment.
