WAWEIS AC Adapter 12V 3A 40W 10ft Cord 524475-051

SKU CH-1SVN-ZV9TH

A 40 W 12 V 3 A AC adapter with a 10 ft cord, worldwide 100-240 V input and FCC, CE, RoHS certification

  • World-wide 100-240V input works anywhere
  • 10 ft cord reaches distant outlets easily
  • 40 W output matches original charger spec
  • Over-current, over-voltage and short-circuit protection included
  • FCC, CE and RoHS certified for safety

Replacement AC Adapter

This WAWEIS AC adapter replaces the Delta EADP-40MB A unit and delivers 12V at 3A for 40W output. It accepts a wide 100-240VAC input at 50/60Hz, making it suitable for worldwide use. The package includes a 10ft power cord for flexible placement. It is designed as a direct replacement for compatible laptop models.

Thermals, Noise and Power Draw

The adapter operates from a 100-240VAC mains supply drawing 1.2A maximum at the input. Built-in protection circuits guard against over-current, over-voltage, short-circuit and total-power fault conditions. An internal smart chip monitors temperature to provide overheating protection during extended use. No moving parts are present, so the unit runs silently.

Bundled Accessories and Software

A 10ft mains cable is included in the box, removing the need to source a separate cord. The adapter carries FCC, CE and RoHS certifications confirming compliance with safety and environmental standards. Manufacturer quality-control testing and a 12-month warranty are noted by the supplier. No software or additional accessories are bundled.

Questions about this item

How do I install the WAWEIS 12V 3A adapter and what step is often missed?

Connect the 10 ft cord to a 100-240VAC 50/60Hz wall outlet, then plug the 12V 3A output into the laptop; the step often missed is verifying the laptop requires exactly 12V 3A before powering on.

What maintenance or replacement will the WAWEIS 524475-051 need later?

The 10 ft cord and wall plug may wear from repeated bending or outlet cycles; replace the entire 40W unit if the over-voltage, over-current, short-circuit or overheating protections trigger permanently.

What limit appears first on the WAWEIS adapter under sustained load?

The 40W total power protection activates first when continuous draw exceeds 12V 3A, shutting down output to prevent overheating until the load drops back within the 1.2A input rating.
