Sherlock: My Dear Wattson, Data Center Managers are raising their intake temperature in order to cut cooling costs and carbon emissions, lower their PUE, and save money. Nowadays most PDUs are installed in the hot aisle where air temperatures are often 10-20°C higher than the inlet side. With Raritan’s PDUs rated at 50-60°, higher than the PDU rating from other manufacturers, managers can safely increase their inlet temperature by many degrees. Most newer equipment can run in temperatures near 40°C so even with a headroom of 10°C, inlet air temperature can be as high as 30°C.
Wattson: And that’s why it makes sense check the PDUs temperature rating before you buy, to save on energy consumption.
