48 V 3.75 A 180 W 4-pin DIN adapter

This 48 V 3.75 A 180 W AC adapter uses a 4-pin DIN connector and is intended as a direct replacement for Fujia model FJ-SW2028A48003850 and compatible variants. It suits owners of laptops or equipment that require this exact voltage, current and connector type.

Installation ease and common issues

The unit accepts worldwide 100-240 VAC at 50/60 Hz and includes a 10 ft power cord, so connection is straightforward. Built-in over-current, over-voltage, short-circuit and total-power protection reduce the risk of damage during a fault. The most frequent issue is ordering the wrong tip size or polarity, which prevents the laptop from charging.

Practical limits of the interface

The 4-pin DIN barrel delivers a fixed 48 V output at up to 3.75 A, so it cannot power devices that need a different voltage or higher current. The connector itself is not a universal standard; pin assignment and dimensions vary between manufacturers, so compatibility must be verified against the original charger. FCC, CE and RoHS certifications confirm basic safety compliance.
