1OverviewThe PSR150-A1 is an AC-input and DC-output power module. ThePSR150-D1 is a DC-input and DC-output power module. Both powermodules provide an output voltage of 12 V and a maximum output of 150W.These power modules have the following features:• Provide output overvoltage, short-circuit, overcurrent, andovertemperature protections. See Table 1 for the protection andauto-recovery features of the power modules.• Two power modules can be connected in parallel to achieve 1+1redundancy and load sharing.• Hot swappable. When you hot swap a power module, make sure thedevice can operate correctly with the remaining power modules.Table 1 Protection and auto-recovery featuresProtectionfunctionProtectionstate Support for auto-recoveryOutput overvoltageprotectionThe power moduleis latched anddoes not supplypower.NoShort-circuitprotectionThe power moduledoes not supplypower.Automatically restores powersupply after the short circuitcondition is resolvedOvercurrentprotectionThe power moduledoes not supplypower.Automatically restores powersupply after the output currentdecreases to an acceptable rangeOvertemperatureprotectionThe power moduledoes not supplypower.Automatically restores powersupply after the temperaturedecreases to an acceptable range
