alinepowersystem.
8.1. Introduction to line power systems
Thelinepowerconversionmodulesinalinepowersystemtakea–48VnominalDCinputvoltageand
convertsittoadifferentoutputvoltage.Therearethreetypesoflinepowermodules:
•
Cordex®HPLPS36–48Vdcto±190Vdclinepowersystem
•
Cordex®HPLPS36±137Vlinepowersystem
• Cordex®HPeLimiter+57Vdistributionsystem
Allthreetypeshavefourindependentoutputchannels,eachwithamaximumoutputpowerof100watts.
Inalinepowersystem(LPS)theoutputofthechannelsfromdifferentmodulescanbecombinedto
supplypowertoloadsatremotelocations.Combiningchannelsallowsforsupplyingpowertoloadsthat
mayexceedthe100wattslimitofasinglechannel.
ThetwoCordex®HPLPS36modulesaredesignedforoutdoorpowerapplicationsthatdeliverpower
throughexistingcoppertelephonewires.TheCordex®HPeLimiter+moduleisdesignedforindoorpower
applicationsthatuselargergaugewireforpowerdelivery.
Warning: Working with line power modules, especially Cordex® HP LPS36 modules, pose
potentially fatal safety concerns. Refer to the appropriate hardware manual before attempting to
wire an line power system or to get more detailed information about the electrical performance of
these modules.
