The ATEN NRGence™ PE5221T eco PDUs are thin form factor intelligent PDUs that contain 21 AC outlets available in IEC or NEMA socket configurations. The lightweight thin form factor eco PDUs have a smaller width and input region than ATEN’s standard and low profile PDUs. The thin form factor series have a 56 mm width that fits tight into server racks providing more space for cooling and maintenance. The smaller design leaves 8% more space in the rack to increase air flow and cool IT equipment more effectively. It also means faster maintenance with easier access to equipment normally installed behind the PDU.

NRGence™ eco PDUs offer real-time power measurement and threshold alerts – allowing you to monitor the PDU’s power status, bank status and circuit breakers, either at the PDU or from any location via a TCP/IP connection.


With the combination of ATEN eco PDUs and eco DC Energy Management Web GUI, a data center is equipped with real-time monitoring, measurement and analysis of energy consumption – with reports of power usage and PUE to meet the ISO 50001 requirements. These indexes will automatically generate customized reports about your data center’s energy use and include energy saving suggestions. The suggestions allow you to optimize energy usage and save money without harming your IT equipment’s reliability. eco DC Energy Management Web GUI provides easy multi-PDU management with an intuitive user-friendly interface that allows you to configure PDUs and monitor the power status of equipment connected to them.
