POPS® (Per Outlet Power Sensing)

Provides power monitoring per individual outlet for Smart or Switched PDUs. Power information includes current, voltage, power (kW), apparent power, crest factor, and power factor. Using our grouping technology, power information is available per device, of devices (application), individual PDU, or cabinet. Learn more

PIPS (Per Inlet Power Sensing)

PIPS technology replaces monitoring at the remote power panel in data centers with higher accuracy and lower cost monitoring of each power circuit attached to a PDU. Learn more

Pro2 Platform (Firmware)

Improve uptime by maintaining high availability to your data through redundantly powered hot-swappable net-work cards and multi-link capability. Gain additional insight into rising loads or heat through multi-level alarms.

Smart Power Distribution Unit

Easy to use and access, CEG can provide Smart PDUs that offer true RMS input current monitors on easy-to-view LED via network or serial connection. These PDUs feature branch circuit protection and are available in a variety of voltages, amperages. Available in single- and three-phase.

Our Server Tech Smart PDUs are guaranteed secure and feature external authentication and authorization support, while SNMP traps provide automated alerts surrounding each outlet’s power and environmental conditions. Optional temperature and humidity probes, with 10 ft. cords, offer flexibility in terms of sensor placement.

Switched Power Distribution Unit

With the ability to turn on, off or reboot outlets individually or as a group, Switched PDUs from Server Tech also feature outlet lock-out, power-up sequencing to reduce power-up inrushes and optional smart load shedding. Switched PDUs feature Smart PDU abilities for network access to power and environmental information.

Metered Power Distribution Unit

When affordable and reliable power distribution for all devices in the equipment cabinet is required, Metered PDUs are the perfect solution. Auto-flip current displays help prevent overloads and simplify three-phase load balancing in high density cabinets, while flexible mounting solutions provide for a basic installation.

Basic Power Distribution Unit

When your greatest concern is delivering reliable, consistent power, CEG can provide a basic PDU that’s a dependable everyday solution for your data center. With branch circuit protection, these PDUs from Server Tech meet UL and IEC data center requirements. Optional flexible mounting and color identification features are available.

Fail-Safe Power Redundancy

Available in metered, smart and switched options, these PDUs offer branch circuit protection. Switched versions feature outlet control, temperature humidity monitoring, linkable expansion and network monitoring.

Our Server Tech FSTS PDUs allow you to receive SNMP-based notifications. Cycle power to individual outlets or groups of outlets in order to reboot servers or power off unused receptacles using outlet control.
