WAWEIS AC Adapter for Yamaha PSR-190, PSR-78

SKU CH-8ER7-PV9GC

Replacement AC adapter for Yamaha PSR-190 and PSR-78 keyboards with 100-240V input and 6.5 ft cord

  • Worldwide 100-240VAC input at 50/60Hz
  • 5 Ft power cord for flexible placement
  • Over current, voltage and short-circuit protection
  • FCC, CE and RoHS certified safety
  • 100% compatible with Yamaha PSR-190 and PSR-78

Target keyboards

This AC adapter replaces the original power supply for Yamaha PSR-190 and PSR-78 portable keyboards. It delivers the correct voltage and connector so the instrument runs from mains power without batteries. Musicians who need a reliable spare for home practice or gigs will find it a direct fit.

Input limits

The adapter accepts worldwide mains voltage from 100 to 240 VAC at 50 or 60 Hz, so it works on most domestic supplies without a separate transformer. The fixed 6.5 ft cord sets the maximum distance from the wall socket to the keyboard. Built-in over-current, over-voltage, short-circuit and total-power protection shut the unit down if the supply exceeds safe limits.

Install notes

Connection is a simple plug into the keyboard's DC inlet and the IEC lead into a mains socket; no tools or configuration are required. The main risk is forcing the barrel plug in the wrong orientation, which can damage the socket. Users should also verify the keyboard's original voltage and polarity markings match before first use.

Questions about this item

Should I choose the adapter for the PSR-190 or the PSR-78 keyboard?

This single adapter replaces the original supply for both the PSR-190 and the PSR-78 models, so no separate version is needed.

What does the 100-240VAC 50/60Hz input mean when I plug it in at home?

It accepts any mains voltage from 100 to 240 volts at 50 or 60 hertz, so the unit works worldwide without a voltage selector.

What does the 6.5 ft power cord length cap in practice?

The 6.5 ft cord limits the distance between the wall outlet and the keyboard to about two metres unless an extension lead is used.
