Replacement AC Adapter for RadioShack MD501

This WAWEIS AC/DC adapter replaces the original RadioShack MD501 power supply catalogued as 42-4059. It delivers worldwide input voltage from 100 to 240 VAC at 50 or 60 Hz.

Upgrade from worn or lost original charger

The adapter serves as a direct replacement when the factory charger fails, is misplaced or shows damaged cables. Built-in overload protection, over-charge and over-discharge safeguards, overheating protection with a smart chip and anti-interference isolation materials maintain stable output. FCC, CE and RoHS certifications confirm compliance with international safety standards.

Questions about this item

Does the 6.5 ft cord reach a wall socket from a desk?

The total cord length is 6.5 ft, which typically spans from a floor outlet to a desktop without an extension lead.

How do I connect the adapter to the MD-501 keyboard without damaging the port?

Align the barrel plug with the MD-501 power jack and push straight in; forcing it at an angle bends the centre pin, which is the most common install error.

When should I replace the adapter if the over-voltage protection trips repeatedly?

Replace the unit if the protection triggers under normal 100-240 VAC input, as repeated tripping indicates internal component fatigue.
