Fans DYTB0838B8UBearing 80x80x38mm 48V 0.63A 4P PWM case fan

SKU CH-8ZGJ-1DPRB MPN DYTB0838B8UBearing

80 x 80 x 38 mm case fan with 48 V PWM control and double ball bearing

  • PWM control adjusts speed to thermal load
  • Double ball bearing extends operational lifespan
  • 48 V 0.63 A suits industrial power rails
  • 80 × 80 × 38 mm fits standard 80 mm mounts
  • Four‑wire interface enables precise speed monitoring

80×80×38 mm 48 V PWM case fan

This 80 mm axial fan runs on 48 V DC and draws 0.63 A through a four-pin PWM connector. Double ball bearings support continuous rotation in industrial and embedded chassis. The 38 mm thickness fits standard 8038 mounting holes.

Suited for 48 V industrial rails

The 48 V supply requirement suits rail vehicles, medical equipment, new-energy vehicles and telecom cabinets that already distribute 48 V DC. Builders using 12 V or 24 V motherboard headers cannot power this fan without a separate converter.

Steady airflow under PWM control

PWM input lets the fan scale speed to thermal load while the tachometer wire reports RPM to the controller. Double ball bearings maintain consistent speed and acoustic profile during long duty cycles in drive cooling or hotel automation racks.

Soalan tentang produk ini

What power source do I need for the 48 V 0.63 A rating of this DYTB0838B8U fan?

You need a 48 V DC supply capable of at least 0.63 A. The fan draws its power directly from that rail through the 4-pin connector.

Will the 4-pin PWM connector work with a motherboard header that only supports 3-pin voltage control?

The 4-pin plug fits a 3-pin header; the fan will run at full speed because the PWM pin is not driven. Speed reporting via the tach wire still functions.

How can I confirm the double-ball-bearing fan is reporting speed correctly after installation?

Check the RPM reading in BIOS or monitoring software; it should vary smoothly with the PWM duty cycle and show no erratic jumps.
