TheinternalcircuitryoftheD2wasengineeredfor12VDCinputONLY.
But,wedosupplyeachCoolDomewithanexternal
highvoltagepowersupply,theDotworkz/MeanWellS‐250‐12Powersupply,whichconvertsthepowertoa
lowvoltage12VDCoutput.ThisallowsyoutousehighvoltagetoindirectlypowertheCoolDome.Itisahighlydurable,heattolerant,A/CtoD/CPowerconverter.The
inputtotheprovidedexternalpowersupplyfollowsstandardA/Cwiringconventions,andistobemountednearbyindoors,oroutdoorsinaweatherratedenclosure..It
canbepoweredbysinglephase110VAC,or220VAC.Itmustbemanuallysettothecorrectinputvoltagerange(110VACor
220VAC),bymovingandsettingtheslide
switchonthesideofthepowersupply,beforepoweringup.TheS‐250‐12ispicturedbelowonthesideofitsTerminalBlock.
