The Expert PDU Energy 8311 is a German-engineered, seven-outlet metered power distribution unit designed to enhance the reliability, security, and energy efficiency of mission-critical IT and AV installations. By combining precise electrical metering with environmental monitoring, it enables operators to identify potential issues before they lead to costly downtime, making it an ideal solution for data centers, server rooms, broadcast facilities, and professional AV racks.
Available as the 8311-1 with seven Schuko Type-F outlets and the 8311-2 with additional Type-A residual-current monitoring, the PDU provides detailed measurements of current, voltage, frequency, phase angle, power factor, active, apparent, and reactive power, as well as energy consumption and differential current. Two independent energy counters are included: one continuously records lifetime consumption, while the second can be reset for project-based or periodic energy tracking.
The integrated sensor interface supports plug-and-play temperature, humidity, and air-pressure sensors, allowing early detection of overheating and other environmental hazards. A bright LED display provides instant access to total current, IP address, and sensor readings, while NTP synchronization ensures accurate time stamping of all logged events.
Seamless integration is achieved through support for REST API, HTTPS, SNMP, MQTT, Telnet, SSH, Modbus TCP, RADIUS, DHCP, and NTP, enabling compatibility with virtually any network management, DCIM, or building automation platform. Free drivers from leading technology partners further simplify deployment and commissioning.
Security and management capabilities are equally comprehensive. Encrypted communications via TLS 1.1/1.2/1.3 and SSH protect sensitive data, while IP-based access control, password authentication, and IEEE 802.1X network authentication safeguard access to the device. Administrators can receive alarms and status notifications through e-mail, syslog, SNMP traps, MQTT, SSH, or Telnet. A built-in audible alarm immediately alerts local personnel whenever configured sensor thresholds are exceeded. Firmware updates can be applied over Ethernet without requiring a reboot, ensuring uninterrupted operation.
