  • World-wide 100–240 VAC input works anywhere
  • 10 ft power cord gives flexible placement
  • Four safety protections guard against faults
  • FCC, CE and RoHS certified for compliance
  • 100 W output with 2.08 A at 48 VDC

What this adapter replaces

This 4-pin -48 V AC adapter supplies 100 W at 2.08 A for laptops that require the FSP Group HW-100-48AC14D-1 or part number 9NA1000700. It accepts a worldwide 100-240 VAC input at 50/60 Hz and includes a 10 ft power cord. Buyers whose devices use a different voltage, connector or wattage cannot use this unit.

Behaviour under continuous load

The switching power supply delivers its rated 100 W continuously thanks to overload and total-power protection circuits. Over-voltage and short-circuit safeguards prevent damage during extended sessions. A smart chip adds overheating protection so the adapter maintains stable output without thermal throttling. Anti-interference isolation materials keep the output clean during sustained operation.

Thermals, noise and power draw

Overheating protection and high-quality wires limit temperature rise during normal use. The adapter runs silently because it has no moving parts. Input current stays within the 100-240 VAC 50/60 Hz design envelope, drawing only what the connected laptop requires up to 100 W. FCC, CE and RoHS certifications confirm compliance with emissions and safety standards.

Questions about this item

Does the adapter run hot or make noise when it delivers the full 100 W continuously?

The unit is a sealed switching supply with overload, over-voltage and short-circuit protection, so it operates silently and its thermal limits are handled by the internal protection circuitry.

What must I already have for this 4-pin -48 V adapter to power my device?

You need a device that accepts a 4-pin -48 V DC input rated for 2.08 A and a mains outlet supplying 100-240 V AC at 50/60 Hz.

Will this 10 ft cord reach the same inlet on the older FSP HW-100-48AC14D-1 unit I am replacing?

Yes, the connector and pin-out match the original FSP Group Inc HW-100-48AC14D-1 supply, so it fits the existing inlet without modification.
