80 × 25 mm 24 V inverter fan

This 80 mm square fan with a 25 mm thickness is built for 24 V industrial inverters such as YASKAWA PLC and ABB units. It draws 0.16 A through a three-wire, three-pin connector and uses a two-ball bearing for continuous operation. The black frame matches standard enclosure aesthetics and the unit ships new in original Melco packaging. Buyers who need a 12 V or PWM-controlled fan cannot use this model.

Sustained 24 V operation

The two-ball bearing design maintains consistent airflow during long duty cycles inside inverter cabinets. With a fixed 24 V supply the rotational speed stays stable without the voltage sag seen in shorter test runs. No LED or speed-reporting circuitry is present so the fan runs silently in the background. Installations that require variable speed control or tachometer feedback must look elsewhere.

Three-pin 24 V power connector

The sole electrical interface is a three-pin header delivering 24 V at 0.16 A. This connector determines whether the fan fits the target inverter board; no adapter or alternative wiring is included. Verify the pinout matches the CA1321-H01 specification before purchase. Systems using a different voltage or pin count will need a different cooling solution.

Questions about this item

How much noise and heat does the 80 x 25 mm fan produce when running continuously on 24V?

The two-ball-bearing design keeps mechanical noise low during 24-hour operation, and the 0.16 A draw at 24 V means modest heat output inside the enclosure.

What power source and connector must I already have to run this 3-pin 24 V cooler?

You need a 24 V DC supply capable of at least 0.16 A and a standard 3-pin fan header or matching Molex-style connector.

Will this 80 mm square fan fit the mounting pattern on my older YASKAWA or ABB inverter?

The 80 x 25 mm frame matches the original Melco MMF-08D24ES RM1 footprint used on those legacy inverters, so it bolts straight in.
