I need a PS20 power supply for my Shure wireless receiver. Is there a commercial alternative?
The following power supply will work:
Triad AC/DC adapter - model WDU12-600
AC input is 120 VAC / 13 watts.\
VDC output is 12 volts / 600 mA.
DC output cable is 72 inches in length.
DC connector is 2.1 mm x 5.5 mm.
Size of the transformer / AC plug enclosure is 3" x 2.2" x 1.9".
This is a linear supply, not a switching power supply. For most situations, this supply can also replace the Shure PS21.
As of January 2015, available from www.mouser.com
Price is $11.59 U.S.
