Compatible Yamaha Keyboards

This AC adapter replaces the original power supply for the Yamaha PSR-730, PSR-740, PSR-630, PSR-640 and DGX-620 portable keyboards. It delivers the required DC output through a barrel tip connector. The unit accepts worldwide AC input from 100 to 240 volts at 50 to 60 hertz. Built-in over-voltage and over-heat protection safeguards the connected instrument.

Musicians Needing a Replacement

Suitable for players who have lost or damaged the factory charger for the listed models. The adapter is a non-OEM accessory certified to CE, FCC and RoHS standards. Buyers who need a power supply for other Yamaha series or different connector sizes should look at alternative units.

Output and Tip Verification

The single specification that decides fit is the DC output voltage and barrel tip dimensions matching the keyboard's power jack. The supplier notes 256% compatibility with the original, but the purchaser must confirm these values before ordering. No other specification overrides this physical and electrical match.

Questions about this item

Which ABLEGRID adapter version should I choose for my Yamaha PSR-730?

This single adapter covers the PSR-730, PSR-740, PSR-630, PSR-640 and DGX-620, so you select the one listing your model.

What does the 100-240V input mean when I plug it into a mains socket?

It accepts any household supply between 100 and 240 volts at 50 or 60 Hz, so the same unit works worldwide without a voltage switch.

What does the barrel tip connector limit in practice?

The barrel tip only fits Yamaha keyboards that use that exact DC jack; it will not connect to devices with a different tip size.
