Zyvpee 4715KL-05W-B30 120mm 38mm 24V 0.4A 2-Wire Inverter Cooling Case Fan

120 mm inverter cooling fan

The Zyvpee 4715KL-05W-B30 is a 120 mm by 38 mm case fan designed for inverter cooling in industrial or server environments. It operates on a 24 V supply drawing 0.4 A through a two-wire power connector. The black frame houses a ball bearing for continuous operation. No LED lighting is fitted.

Sustained load behaviour

Under continuous duty the ball bearing maintains consistent rotation without the wear patterns seen in sleeve designs. The 24 V input delivers stable torque across the operating range so airflow does not decay as temperature rises. The two-wire interface provides power only, so speed is fixed unless an external controller varies the voltage.

Two-wire voltage control limits

Speed regulation depends entirely on the source voltage because the fan lacks a PWM or tachometer line. The 0.4 A draw at 24 V sets a hard ceiling on airflow that cannot be exceeded by software. Builders who need variable speed or RPM monitoring must add external circuitry or choose a different connector type.
