Direct replacement for Dunlop M237

This 18V 2A AC adapter replaces the Dunlop M237 power supply. It delivers 18 volts at 2 amps through a barrel connector with a 2.1mm inner diameter and 5.5mm outer diameter.

Check voltage polarity and plug dimensions

Before ordering, confirm that the device requires 18VDC output and accepts a 2.1mm by 5.5mm barrel plug with negative centre polarity. Verify the original adapter is rated at 2A or 2.0A. The unit operates on a worldwide input range of 100-240VAC at 50/60Hz, so no separate voltage selector is needed.
