Product identity

This AVC 17251 DATA1551B8M unit is a 48V 0.98A power adapter built with a metal aluminium shell for high temperature resistance. It is intended for technicians maintaining inverters, industrial computers, servers and similar high-end equipment.

Interface and environmental limits

The adapter uses a 4-pin interface with red wire positive and black wire negative, and carries a PWM intelligent speed control function alongside speed measurement. Service life is rated at 10.0000 hours at 25 °C with 45 to 85% relative humidity.

Replacement scope

It replaces worn or failed cooling fans in medical, rail vehicle, drive cooling, hotel, industrial cleaning, electronic product, new energy vehicle and supermarket installations. Buyers who need a different voltage, current rating or bearing type should look elsewhere.

Questions about this item

How do I decide between the 17250 and 17050 size options for this AVC fan?

The 172 × 150 × 50 mm frame (17250) is the standard fit; the 17050 variant is slightly smaller and only needed if your chassis cut-out matches that footprint.

What does the 48 V 0.98 A rating tell me about actual airflow and noise in a server chassis?

At the rated 48 V the double-ball bearing motor draws 0.98 A to deliver high air volume and pressure; PWM speed control lets you lower RPM for quieter operation when full cooling is not required.

What does the 4-pin PWM interface actually control and what are its limits?

The 4-pin connector carries 48 V power (red positive, black negative) plus a PWM signal for intelligent speed control and a tach output for speed measurement; it does not support voltage-only regulation.
