Fans BP1203848M-03 DC48V axial flow cooling fan

Industrial 48 V axial fan

This 48 V DC axial flow fan is built for industrial and embedded cooling where a stable high-voltage supply is already present. It suits engineers integrating airflow into medical devices, rail equipment, EV subsystems or rack-mounted electronics. The compact frame fits tight mechanical envelopes without requiring a separate low-voltage rail. Buyers needing a 12 V or 5 V PWM case fan for a desktop PC cannot use this unit.

Sustained 48 V operation

Running directly from a 48 V DC bus eliminates the losses and space of a step-down converter, so the motor maintains steady torque during continuous duty cycles. The axial blade geometry delivers consistent static pressure across the operating range without the thermal throttling seen in voltage-regulated alternatives. No RPM, airflow or acoustic figures are supplied, so exact performance under load cannot be quoted here.

Replaces custom 48 V axial units

The BP1203848M-03 drops into designs that previously specified a custom ebm-papst 48 V axial fan, removing lead-time and minimum-order constraints. The upgrade is worthwhile when the bill of materials must consolidate to a single authorised distributor part number. It does not replace 12 V chassis fans, nor does it fit standard 120 mm PC mounting holes without a mechanical adapter.
