The PA150 adaptor replaces the PA5D and is environmentally friendly by reducing the power when the musical instrument is turned off; saving you money! Plug it in and play your instrument without having to worry how long the batteries will last. The PA150 is designed to eliminate your constant need for fresh batteries by using efficient AC operation. Recommended for YPG225, DGX220, YDD50 and DD65. Also compatible with past models recommending the PA5D adapter.
