AC adapter for Knox 61-key keyboards

This WAWEIS power supply replaces the original charger for Knox KN-MK301, MK-301 and MK-301B portable keyboards. It delivers the correct voltage and polarity so the instrument powers on and charges reliably. Musicians, students and teachers who have lost or damaged the factory adapter can use this unit as a direct substitute.

Replaces a lost or faulty factory charger

The upgrade is worth it when the original cable is frayed, the plug no longer seats firmly or the brick has stopped supplying power. A 6.5 ft cord gives extra reach between the wall socket and the keyboard stand. Built-in over-current, over-voltage, short-circuit and total-power protection guards the keyboard's internal circuitry during everyday use.

Limited to the listed Knox models

The adapter only fits the three specified 61-key models; it will not work with other Knox keyboards, different brands or any laptop. Input voltage covers 100 to 240 VAC at 50 or 60 Hz for worldwide mains compatibility. Certifications include FCC, CE and RoHS, but the unit lacks USB ports, battery-charging circuits or adjustable output for other devices.

Questions about this item

What wall voltage range does this 100-240VAC adapter accept?

It works on any mains supply from 100 to 240 volts at 50 or 60 hertz, so it can be used worldwide without a voltage converter.

How do I connect the 6.5 ft cord to the Knox KN-MK301 keyboard?

Plug the barrel connector firmly into the keyboard's DC input jack, then insert the mains plug into a wall socket; the step often missed is seating the barrel fully until it clicks.

When should I replace the cable if the insulation wears?

Replace the entire adapter if the 6.5 ft cord shows cracks, exposed wire or the plug becomes loose, as the built-in short-circuit and over-voltage protection cannot be serviced separately.
