Australian approved this is the often difficult to find AC/DC LINEAR power supply that is suitable as a replacement for OEM Shure power supply PS20E, used on SHURE equipment that require a draw of no more than 12v 300ma with a 2.1mm tip  

For example if your units power requirement is 12v 30ma, 12V 60ma, 12V 250ma, 12V 300, 12V 0.3a amp etc etc... it will suit.

Do you know what is meant by a Negative Center TIP? A unit power supply with a negative TIP indicates that the center (tip) of the output plug is Negative (-) and the barrel of the output plug is Positive (+). See the display picture, as  this picture is usually stamped on to the body of the unit or within the owners manual.  If you are unsure then please ask.
