How Important is Temperature Rating When Selecting a PDU?
October 15, 2015
Power distribution units (PDUs) are usually installed in the back
of cabinets behind hot air exhaust from equipment, which is potentially the
hottest part of every data center. Depending on the expected ΔT from servers
ranging from 25°F to 30°F (13°C to 20°C), the heat at the rear of cabinets or
hot aisle containment can reach 110°F to 140°F (43°C to 60°C). In this type of
environment, there are very few devices that can continuously operate reliably
eConnect® PDUs currently have the highest ambient
operating temperature rating of any PDU in the market. eConnect PDUs have been
specially designed and tested for continuous operation in ambient air
temperatures up to 149°F (65°C) to exceed the anticipated temperatures in a
typical contained aisle.
To keep the product safely operational at such high
temperatures, strategically placed air vents, a larger power supply, high
temperature components and other elements were included in the design. eConnect
PDUs comply to safety standards by the International Electrotechnical
Commission and are UL Listed.
Additionally, the eConnect’s streamline design minimizes the
space it occupies within the cabinet. On units with multiple breakers, the
outlets are arranged in an alternating pattern, so you distribute load more
evenly as you plug in equipment. For intelligent PDUs, the LCD display is
centrally located so that it is easy to read when the PDU is installed. It is
possible to access the unit remotely using a web browser for setup, monitoring
and control. IP consolidation allows access of up to 20 PDUs through a single
Ethernet connection and IP address. Alternately, the PDU supports SNMP so that
it can be monitored with third-party monitoring software.
