Suitable for use in outdoor enclosures or liquid cooled applications, these pcb mounted power modules accept a wide range AC input and deliver an adjustable, regulated output. High ambient temperatures can be tolerated as the conduction cooled baseplate can withstand -40 to 100°C temperatures. These third generation modules also have a PMBus™ interface with read/write capability for remote monitoring and programming. |**Features**|**Benefits**| |---|---| |• Compact 4” x 2.4” x 0.53” Brick Package|• Less Board Area Required| |• Metal Case|• Easier Thermal Management and Lower Radiated EMI| |• High Power Density, High Efficiency|• Less Waste Heat to Manage and Reduced AC Power Consumption| |• 100°C Rated Baseplate Temperature|• Cold plate / Conduction Cooling for Fanless and Rugged Environments| |• PMBus™ Interface|• Remote Monitoring and Programming via i2C| |• Optional Droop Mode Load Sharing|• Simplified Paralleling for Higher Power or Redundant Applications| ## **Model Selector** ||||Nominal|Nominal|Nominal||Output|Output|Maximum|Maximum|Maximum||Maximum|Maximum||||Droop Mode|Droop Mode| |---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---| |Model||||Output|||Adjust||Output||||Power||Mounting|||Current|| ||||Voltage (V)|||Range (V)|||Current (A)||||(W)(1)||Inserts|||Share|| |PFH500F-12-000-R||||12||9.6 - 14.4||9.6 - 14.4||42||||504|3.3mm Ø Non-threaded||3.3mm Ø Non-threaded|No|| |PFH500F-12-0D0-R||||12||9.6 - 14.4||9.6 - 14.4||42||||504|3.3mm Ø Non-threaded||3.3mm Ø Non-threaded|Yes|| |PFH500F-12-100-R||||12||9.6 - 14.4||9.6 - 14.4||42||||504|3mm (M3) Threaded|||No|| |PFH500F-12-1D0-R||||12||9.6 - 14.4||9.6 - 14.4||42||||504|3mm (M3) Threaded|||Yes|| |PFH500F-28-000-R||||28||22.4 - 33.6||||18||||504|3.3mm Ø Non-threaded||3.3mm Ø Non-threaded|No|| |PFH500F-28-0D0-R||||28||22.4 - 33.6||||18||||504|3.3mm Ø Non-threaded||3.3mm Ø Non-threaded|Yes|| |PFH500F-28-100-R||||28||22.4 - 33.6||||18||||504|3mm (M3) Threaded|||No|| |PFH500F-28-1D0-R||||28||22.4 - 33.6||||18||||504|3mm (M3) Threaded|||Yes|| |PFH500F-48-000-R||||48||38.4 - 52.8|||10.5|||||504|3.3mm Ø Non-threaded||3.3mm Ø Non-threaded|No|| |PFH500F-48-0D0-R||||48||38.4 - 52.8|||10.5|||||504|3.3mm Ø Non-threaded||3.3mm Ø Non-threaded|Yes|| |PFH500F-48-100-R||||48||38.4 - 52.8|||10.5|||||504|3mm (M3) Threaded|||No|| |PFH500F-48-1D0-R||||48||38.4 - 52.8|||10.5|||||504|3mm (M3) Threaded|||Yes|| ||||||||||||||||||||| |**PFH500F**||**-**|||**28**||**-**||**1**|||||**D**||**0**|**-**|**R**|| ||||||||||||||||||||| |Output voltage 12, 28, 48V||Output voltage 12, 28, 48V|Output voltage 12, 28, 48V|||0
