Inline-metered PDU with 4 single-phase power supplies

Expert PDU Energy 8341 for more security and energy efficiency in IT and AV installations
  • Demonstrably fewer and shorter outages of your critical IT and AV infrastructure
  • Detect AV and IT problems at an early stage: Proactive power and environment monitoring
  • Increased energy efficiency (Green IT and AV): Reduction of electricity costs and CO2 emissions
  • Integrate anywhere: Quickly and easily integrate anywhere with API interface: REST API, HTTPS, SNMP, Telnet and MQTT
Massive time and cost savings through plug-and-play drivers from our technology partners

8341-1: 4x IEC C19         8341-2: 4x IEC C19  (RCM Type A)

Key Features
  • Precise current metering of up to 9 units and residual current
  • 2 connectors for plug-and-play sensors
  • Fast and easy installation
  • NTP function can be activated
  • Hotswap slot for easy maintenance for uninterrupted operation
Metering function
  • Power consumption metering (kwH) with 2 energy counters: one counter counts consistently, the other counter is resettable
  • Metering of current (A), voltage (V), phase angle, power factor, frequency (Hz), active power (W), apparent power (VA) and reactive power (VAr)
  • 2 energy counters per output: one counter counts consistently, the other counter is resettable
  • Metering of differential current type A (mA)
  • Metering of 4 separate phases
  • 2 connectors for combined plug-and-play sensors (temperature, humidity and air pressure) to prevent often occurring physical hazards like overheating and increased humidity or air pressure

Suitable accessories


The Expert PDU Energy 8341 enables power distribution and metering of energy, current and voltage from four separate phases. Two energy meters are integrated per phase. On the front side of the device are four load outputs with IEC C19 connection (16 A). The hotswap slot allows a smooth replacement of the processor/power supply module. This ensures an uninterrupted power supply to the connected loads.

The devices have SNMPv3, SSL and IPv6 capability and support Telnet, Radius and Modbus TCP. Thanks to sensor connectors, environment temperature, humidity and air pressure can be monitored with plug-and-play sensors. Expert PDU Energy 8341 inline meters are available in variants with and without type A residual current monitoring. In this case, the user receives warning messages when fault currents occur. This enables preventive maintenance measures to be taken even before downtimes occur.
