Executive Summary

  • High Density Outlet Technology

    Short on real estate, high on rack components?

    Choose High Density Outlet Technology
    High Density Outlet Technology (HDOT) has the most outlets in a 42U intelligent Rack PDU with industry standard C13 and C19 outlets. Comes with high native cord retention and color-coded alternating-phase outlets for easy cabling. Learn how our HDOT PDUs with Alternating Phase Technology improved a Networking Company's power density.
  • Alt Phase Technology

    Looking for the perfect load-balancing solution?

    Choose Alternating Phase
    Alternating phase outlets alternate the phased power on a per-outlet basis instead of a per-branch basis. This allows for shorter cords, quicker installation and easier load balancing for 3-phase rackmount PDUs. Shorter cords mean less mass, making them less likely to come unplugged during transport of the assembled rack. Read the Alt Phase Executive Summary.

Power Measurement Solutions

Per Outlet Power Sensing |

The best outlet power measurement technology on the market for data center rack-level power monitoring.

Adds Per Outlet Power Sensing (POPS) to the Switched PDU which provides power monitoring per an individual outlet/device. Power information per individual outlet /device includes current, voltage, power (kW), apparent power, crest factor, and power factor. Using our grouping technology, power information is available per device, groups of devices (application), individual PDU or cabinet.

Per Inlet Power Sensing |

The best infeed power measurement technology on the market for data center rack-level power monitoring.

PIPS technology replaces power monitoring at the RPP (Remote Power Panel) in data centers with higher accuracy and lower cost monitoring of each power circuit attached to a PDU. This feature enhances equipped Smart, Switched, and POPS PDUs with the most accurate and extensive metrics on the market. Expect the same quality and functionality on current intelligent PDUs, but with an increased level of information to help you make the critical decisions regarding your facility.
