Compatible replacement adapter

This 3 V DC adapter replaces the original supply for the KA12D030030022U model and delivers a current range of .3 A to 1 A. It accepts a wide input of 100 V to 240 V at 50 Hz or 60 Hz for worldwide use. The unit includes a 6.5 ft power cord and carries FCC, CE and RoHS certifications. Built-in protections cover over current, over voltage, short circuit and total power faults.

Suits owners of the listed Ktec model

Buyers needing a direct replacement for the specified KA12D030030022U unit will find full voltage and connector compatibility. The Class 2 transformer design meets the original safety class. Users who require a different output voltage, a higher current rating or a battery pack instead of an AC adapter should look at another product.

Deciding specification: 3 V DC output at .3 A to 1 A

This single rating determines whether the adapter matches the device's power input requirements. Verify that the laptop or peripheral expects 3.3 V at up to 1 A before purchasing. If the equipment calls for a different voltage or a higher amperage, this adapter will not operate correctly.

Questions about this item

Will this 3 V DC charger run alongside the original power brick I already own?

The adapter accepts 100-240 V AC at 50/60 Hz and delivers 3 V DC at up to 1 A, so it can operate on the same mains circuit as your existing brick.

How do I confirm the 3.3 V output is stable after connecting it?

The unit includes over-voltage, over-current, short-circuit and total-power protection; a steady LED on the plug indicates normal operation.

What cables come in the box and what must I source separately?

A 6.5 ft power cord is integrated; no extra cables or tips are included.
