The FSP135-AJBU3 is an AC/DC desktop power adapter manufactured by FSP Technology Inc., designed to provide reliable off-board power for electronic equipment. This unit delivers a total output power of 135W at a fixed voltage of 19.5V, making it suitable for powering laptops, monitors, and industrial control systems that require standardized external power supplies.
Electrical performance is optimized for global compatibility, accepting an input voltage range of 90 to 264VAC across frequencies of 47 to 63Hz. The adapter draws a maximum input current of 1.2A under full load conditions while maintaining no-load power consumption below 0.5W. Touch current is limited to 0.25mA at 264VAC, ensuring compliance with safety standards for user contact.
Safety features include integrated overvoltage protection that triggers automatic shutdown if the output exceeds 29V due to internal faults, with recovery achieved through an AC power cycle. The desktop form factor allows for flexible placement near workstations or equipment racks without requiring permanent mounting. Engineers and procurement teams can rely on this adapter for consistent power delivery in commercial and light industrial applications.
The adapter provides a fixed output voltage of 19.5V.
The maximum input current is 1.2A when tested at 100Vac and 240Vac under full load.
The unit automatically shuts down if output voltage exceeds 29V and resumes normal operation after an AC power reset.
