48 V PWM axial fan for power equipment

This Zyvpee DBTD1551B8U is a 170 mm DC axial fan built for 48 V systems. It draws 2.16 A through a standard 4-pin PWM connector. The 2-ball bearing supports continuous operation in industrial power supplies or inverter units.

Suits 48 V rack gear; not for desktop headers

Technicians maintaining 48 V power shelves or inverter chassis can mount this 172 x 51 mm frame directly. Builders assembling standard ATX computers should look elsewhere because the voltage and current rating do not match motherboard fan headers.

48 V 2.16 A input decides fit

The single specification that determines compatibility is the 48 V 2.16 A power requirement. Only systems supplying that exact voltage and current through a 4-pin PWM header can drive this fan correctly.

Questions about this item

How do I choose between the 48 V 2.16 A version and other voltage options?

This model is the only one listed; it runs on 48 V DC at 2.16 A with a 4-pin PWM connector and 2-ball bearing.

What does the 2.16 A current draw mean once the fan is installed?

The fan will draw up to 2.16 amps from a 48 V rail, so the supply or inverter must deliver that current continuously.

What does the 4-pin PWM interface control in practice?

The fourth pin carries a PWM signal that lets the motherboard or controller vary the fan speed dynamically.
