The Schleifenbauer Intelligent 0U Vertical rPDU Three Phase 32A Inline Energy Meter 1 CEE 5G6 provides accurate, real-time monitoring of power consumption with measurement data is accessible both locally and over the network.
Schleifenbauer Inline Meters with Flexible Communication Options
Schleifenbauer Inline Meters allows you to add intelligent metered PDU functionality to your existing non-intelligent power distribution paths. The inline meters provide am intelligent, cost-efficient solution for metering energy usage across both single-phase (16A/32A) and three-phase (16A/32A) environments.
Designed for seamless integration in vertical and horizontal setup. The horizontal Inline Meter fits a half-width 19-inch form factor, allowing two units to be mounted side by side in a standard rack. Installed between the power feed and connected equipment, the meter continuously measures current and voltage to calculate real-time power consumption. Data is displayed ocally via the built-in screen and transmitted to your monitoring system via your preferred communication protocol.
In some colocation or multi-tenant data centre environments, metering via intelligent PDUs within client-owned racks may not be allowed for purposes such as billing, monitoring or security. Clients often retain full control over their racks, restricting direct access to infrastructure and energy data. To overcome this limitation, a Schleifenbauer Inline Meter can be installed externally, between the power source and the client?s PDU. This allows the data centre to monitor energy consumption independently of the client?s infrastructure, enabling:
Accurate billing based of actual usage
Independent monitoring without accessing client equipment
Enhanced security by restricting data access to the defined metering point
Key Benefits for Server Rooms and Data Centres

Metered Input PDU Functionality
Schleifenbauer Inline Meters measure the total incoming energy consumption. The Inline Meter monitors the complete flow of current, voltage, power, and energy (kWh) from the power source into the device. This data provides valuable insights for analysing and optimising energy usage within a data centre or server room, supporting cost control, capacity planning, and the identification of inefficiencies. If the Inlet Meter is configured for multiple phases, energy consumption is measured per phase. If divided into multiple protected groups, consumption is monitored individually per group.
Measured parameters include: Voltage (V), Voltage dips/spikes (V), Current (A), Peak current (A), Active power (W), Apparent power (VA), Reactive power (VAR), Energy (Wh), Apparent energy (VAh), Total harmonic distortion (%), Crest factor, Frequency (Hz), Power factor. Monitoring energy consumption also helps to improve Power Usage Effectiveness (PUE) , a key metric for energy efficiency in data centres and supports compliance with the EU Energy Efficiency Directive (EED).
Choose Your Plug, Cable Length and Entry Position
When configuring a Schleifenbauer Inline Meter, you have full flexibility in selecting the cable entry position, cable length and plug type. Depending on your chosen configuration (such as phase connection and amperage), various plug options are available, including:
CEE (1P+N+PE or 3P+N+PE, both 6h)
Schuko (CEE 7/4)
C14 / C20
BS 1363
Wieland GST18i3 or GST18i5
Swiss T13 / T23 If preferred, a fixed cable can be replaced with a chassis connector, such as a C14 or C20 inlet, a terminal block, or a Phoenix QPD connector
The standard cable length is 3 metres, but this can be freely specified to suit your installation environment. Cable entry position ? whether from the bottom, top, front or rear of the PDU ? is also tailored to fit the layout of your rack infrastructure.
Exit Lead Options
The Schleifenbauer Inline Meter can be supplied with exit lead solutions featuring fixed power cables, pre-fitted with IEC60309 plugs for immediate integration into your electrical infrastructure. These are available in both single-phase (1P+N+PE) and three-phase (3P+N+PE) variants, depending on your power distribution requirements. If your application demands a different connector type, we offer full flexibility to provide customised terminations ? including national plug types, industrial connectors, or open-end cable for direct termination. This makes the Inline Meter suitable for a wide range of use cases, from rack-level integration to facility-wide retrofits. All exit lead configurations are assembled to order, ensuring optimal compatibility with your installation, and maintaining Schleifenbauer?s hallmark of short lead times and high-quality standards.
Display App
A key feature of the communication module is the absence of a fixed display, eliminating a potential single point of failure. Instead, the module connects via NFC to a tablet or smartphone, which functions as a remote Inline Meter display. Using the dedicated Display App, users can easily pair with the Inline Meter and access real-time measurement data, device information, and all functionalities typically available through a built-in display.
EnerTree DCEM Software
Schleifenbauer EnerTree is an advanced Data Centre Energy Management (DCEM) software, included free of charge with every PDU 5.0. Unlike traditional solutions where intelligence resides in each individual PDU, EnerTree centralises monitoring and control through a Gateway or Controller Module. This allows all connected PDUs to act as intelligent measurement devices, streaming real-time data to the software ? either locally (EnerTree Lite) or centrally (EnerTree Platform).
The system supports auto-discovery, intuitive dashboards, and real-time analysis of power and environmental data. With features such as PUE calculation, historical trends, threshold alerts, and predictive maintenance, EnerTree gives data centre managers full control over energy usage and infrastructure health.
This module provides an advanced energy management solution within the EnerTree DCEM software platform, ideal for data centres managing large numbers of PDUs. It supports up to 10,000 PDUs (100 per IP address) and offers advanced features such as group switching, device configuration, and custom reporting. With fast data refresh rates (once per second) and configurable alerts, the module is perfectly suited for environments where detailed insights and extensive reporting are essential. The Gateway Module enables automatic discovery of new PDUs and centralised control of system settings.
Thanks to its seamless integration with EnerTree, data centre managers can easily generate reports and adjust system configurations without being limited by the PDU?s internal capacity. Integration with any DCIM platform is also possible via EnerTree, enabling smooth interoperability with other data centre management tools. The module is equipped with one 1 Gbps Ethernet RJ45 port, two Databus RJ45 ports, and two USB-A ports, as well as a secondary 1 Gbps Ethernet connection via USB. All interfaces support zero-touch provisioning for plug-and-play deployment.
Controller Module
The Controller Module is ideal for data centres seeking a standalone management platform within the PDU or direct integration between the PDU and existing DCIM software ? particularly in conventional setups. With EnerTree Lite embedded in the communication module, this solution enables communication with the PDU and supports up to 100 PDUs in a ring configuration. The module includes all the key features expected from a modern intelligent PDU, such as threshold configuration, scheduling, and simplified reporting and dashboard options via the integrated web interface. This makes the Controller Module particularly well-suited for data centres that require traditional device-level control and alerting. The module is equipped with a 1 Gbps Ethernet RJ45 port, two Databus RJ45 ports, and two USB-A ports, as well as a secondary 1 Gbps Ethernet connection via USB. All interfaces support zero-touch provisioning for easy plug-and-play deployment.
Daisy Chain Module
This module is designed to link multiple PDUs within a ring network. One PDU must be equipped with a Gateway Module (with EnerTree DCEM) or a Controller Module (with embedded EnerTree Lite). Up to 99 additional PDUs can be fitted with Daisy Chain Modules. This setup enables real-time data streaming, with the Daisy Chain Module acting as a data relay, sending measurements via the databus to the Gateway or Controller, which then communicates with the network. The module has no Ethernet port, adding a layer of security by preventing unauthorised access. It supports up to 100 PDUs per IP address, offering scalable, efficient expansion with reduced hardware needs and simplified installation. Equipped with two Databus RJ45 ports (with status indicators) and two USB-A ports, all interfaces support zero-touch provisioning for plug-and-play deployment.
