Dimensional parameters of hot-swappable power distribution units for base stations

Hot-swappable PDUs for base stations typically come in 1U to 5U rack-mount sizes, with modular designs allowing flexible installation and easy replacement without interrupting power.Eaton HotSwap MBP and FlexPDUForm Factor: Rack-mountable, can be installed at the back, side, or top of UPS units, or directly in racks .Rack Units: Commonly 1U for basic rack PDUs (e.g., EHBPL3000R-PDU1U), .Power Ratings: 3 kVA, 6 kVA, 11 kVA single-phase, and 11 kVA three-phase options .Installation Flexibility: Hot-swappable modules allow UPS replacement or battery servicing from the front panel without removing the unit from the rack .Output Connectors: Multiple options including French, Schuko, British, IEC, or hard-wired terminal blocks .Lambda HFE SeriesForm Factor: 1U 19-inch rack units.Module Slots: HFE1600 uses 5 slots, HFE2500 and HFE3500 use 4 slots for hot-swappable modules .Power Ratings: 1600 W, 2500 W, 3500 W.Output Voltages: 12 V, 24 V, 32 V, 48 V depending on model .Communication: PMBus interface standard on HFE3500, optional on lower models .Primax P600 SeriesForm Factor: 19-inch rack, 5U expansion sub-rack.Current Capacity: Up to 200 A at 125 VDC .Modularity: Hot-swappable modules for easy maintenance and future expansion.Footprint: Designed for compact installation in constrained spaces, suitable for base station DC backup systems .SummaryHot-swappable PDUs for base stations are designed for modular, rack-mounted deployment, typically ranging from 1U to 5U depending on power rating and module count. They support front-panel hot-swapping, multiple output connector types, and flexible installation positions relative to UPS units. These features ensure continuous power availability while allowing maintenance or upgrades without service interruption, making them ideal for telecom and data center environments .
