3 Specications
PS3500 has a wall-mount, multi-slot backplane accepting hot swappable plug-in power
converter modules that provides an isolated output at 24 V DC nominal.
Each power module has an individually isolated input port accepting either AC or DC that
providesinrushcurrentlimitingandpowerfactorcontrol.Theoutputportiscompletely
isolatedfromtheinputandprovidesupto15Apermoduleatanominal24VDC(adjustable
22.5to30Vfromchassismountedtrimmer)withaloadsharingcongurationforparalleled
output operation. Input and output lines can be wired independently or in parallel providing
N+1 redundant structures.
SystemcongurationisobtainedbywiringandcongurationDIPswitchesonthevarious
backplane slots leaving power modules interchangeable and easily swappable under load.
AllrelevantfailuresinthemodulesaredetectedandsignaledbyindividualLEDsandalarm
relaysprovidingaexiblecombinationofredundancy,faulttolerance,andautomaticfault

• Nominal output 24 V/15 A per module
• Nominalinputof90to250VAC/90to300VDCpermodule
• N+1 redundancy
• Automatic load-sharing
• Higheciency(upto91%)

• Redundancyonsupplyline
5.1 N+1redundancy

maximumcurrentprovidedbytheoverallnumberofmodulesminusone.Basedonthe
backplane size, N can be any number between 1 and 5.
5.2 Hotswapping
Hotswappingallowsreplacementofamoduleunderpowerwithoutanyvisiblefunctional
impact on the output side. Hot swapping is allowed only in an environment where no
hazardousmaterialsarepresent.ThehotswappingfeatureisnotpermittedinaClassI/Div2
area or Zone 2 area unless under a hot permit.
5.3 Automaticload-sharing
