SKU CH-ZPZK-VH52R

  • World-wide 100-240 VAC input works across regions
  • 5 ft power cord gives flexible placement
  • FCC, CE and RoHS certifications confirm safety standards
  • Over-current, over-voltage and short-circuit protection safeguards equipment
  • Smart-chip thermal and overload guards prevent overheating

Purpose and compatibility

This WAWEIS 9V AC adapter replaces the original power supply for Roland GR55, FR-2, XV-2020 and Boss 9VDC guitar synthesizers and accordions. It delivers the correct voltage and polarity for those specific instruments so they operate without modification.

Installation and common issues

The unit plugs directly into a 100-240VAC 50/60Hz mains outlet and connects to the device with a 6.5 Ft cord, requiring no tools or configuration. Built-in over-current, over-voltage, short-circuit and overheating protections reduce the risk of damage if the supply is accidentally overloaded or the cable is pinched.

Capacity limits and headroom

The adapter is rated for the exact 9VDC draw of the listed Roland and Boss models, providing stable power for normal playing and patch editing. It is not designed for devices that require higher voltage, higher current or a different connector type, so it cannot support larger multi-effects racks or rackmount synths.
