Compatible Models

This WAWEIS AC adapter replaces the power supply for Optimus Concertmate-575, CASIO CTK-40 and Concertmate 650 keyboards. It matches the original Cat. No. 42-4029 and 42-4006 specifications. The unit is new and built with 100% OEM-compatible components.

Build Integration

The adapter accepts world-wide input voltage from 100 to 240 VAC at 50 or 60 Hz, so it works on mains power in many regions without a separate converter. A 6.5 ft power cord provides reach to the wall outlet while freeing the keyboard from a short tether. No internal battery is required for operation.

Sustained Load Behaviour

Safety circuitry includes over-current, over-voltage, short-circuit and total-power protection that remains active during extended playing sessions. Overheating protection uses a smart chip to regulate temperature when the adapter runs continuously. FCC, CE and RoHS certifications confirm compliance with recognised safety standards.
