Sunon 48 V four-wire case fan
The Sunon PSD4808PMBX-A is an 80 mm square case fan built for 48 V DC systems. Its four-wire connection supports PWM speed control and tachometer feedback for precise thermal management in servers or industrial chassis.
Practical limits of the 48 V PWM interface
The fan draws 22.1 W at full speed, so the 48 V rail and header must supply that power continuously. Four-wire control only works when the motherboard or fan controller provides a PWM signal and reads the tachometer line; three-pin headers will run the fan at fixed maximum speed.

Questions about this item
Should I choose the 80 mm or 8038 version for my 48 V system?
The model PSD4808PMBX-A is an 80x80x38 mm fan; 8038 simply denotes that 80 mm by 38 mm size, so there is only one version to select.
What does the 22.1 W rating mean when the fan is installed in my chassis?
At 48 V the fan draws 22.1 W, delivering maximum airflow and speed; ensure your fan header or power supply can provide that wattage continuously.
