It accepts worldwide AC input from 100 to 240 volts at 50 to 60Hz and delivers a DC output. The unit is a non-OEM replacement built with over voltage and over heat protection. CE, FCC and RoHS certifications are included.

Verify Connector Polarity and Dimensions Before Use

Check that the DC output voltage and the tip size match the original charger exactly; the supplier notes the connector size must be confirmed by referencing the product pictures. Ensure the piano requires a 12 volt DC input and that the polarity symbol on the device matches the adapter. Do not connect if the plug dimensions or polarity differ from the original equipment.

Sustained Operation Requires Adequate Ventilation

During extended playing sessions the adapter will generate heat; the manufacturer advises keeping it in a suitably ventilated area with controlled humidity. Avoid placing the unit on leather, fabric or other skin products that can trap warmth. If any abnormal condition appears during long-term use, discontinue operation immediately and contact the seller for assistance.

Questions about this item

Does the package include the power cord for the wall socket or just the adapter brick?

The package includes one new AC DC adapter power charger. The supplied images show the complete unit with attached cable, so no separate mains lead is required.

How do I confirm this 12V 3A unit matches my Donner OURA S100, R300 or S300 keyboard?

Check that your piano requires DC 12V output and verify the barrel tip dimensions against the product photos before ordering.

What does the 100-240V input range mean for daily use?

The adapter accepts mains voltages from 100 to 240 volts at 50 or 60 Hz, so it works worldwide without a voltage converter.
