The Schleifenbauer Intelligent Double Horizontal Switched rPDU has a 1 phase 16A metered input with 12 switched outputs including 6 IEC locking C13 and 6 IEC locking Combi CX C13/C15 outlets. Schleifenbauer switched PDUs offer all the capabilities of metered inlet models, with the added benefit of remote outlet control. Authorised users can securely power-cycle individual outlets, reboot connected devices, and implement power sequencing to minimise inrush current, improving energy efficiency, infrastructure control, and service continuity.
Schleifenbauer Switched PDU Features
Energy Efficiency: Reduce unnecessary power consumption by disabling idle equipment, lowering operational costs and improving sustainability.
Operational flexibility: Remotely manage power distribution without physical access to the rack, ideal for large-scale or restricted environments.
Optimised Energy Usage: Gain granular insight into outlet-level consumption to identify inefficiencies and reduce unnecessary energy usage. Billing-grade accuracy (+/- 0.5%).
Enhanced Security and Safety: Prevent unauthorised device connections and quickly shut down critical equipment in emergencies or failure scenarios.
Automation and Integration: Support for scheduled switching, load balancing and integration with automation platforms enhances resilience and control.
Bi-stable Relays: Minimise energy consumption by using relays that require power only during switching, not to maintain the current state?resulting in lower internal heat and increased efficiency.
Near Zero Voltage Switching (N-ZVS): Switching occurs at the lowest point of the AC waveform, reducing electrical stress and prolonging the lifespan of connected devices.
Outlet Switching Delay: Configurable delay per outlet or group prevents inrush current, evenly distributes the load and ensures stable power-up behaviour.
Communication Modules: Gateway (standard) with Controller and Daisy Chain options.
Body Colour Choice: black, red, blue, green, orange, yellow and grey.
Switched PDU Functionality
Switched PDUs measure the input to the PDU and provide the facility to remote switched outlets on or off.
Incoming Energy Monitoring
Schleifenbauer Monitored PDUs measure the total incoming energy consumption. The unit monitors the complete flow of current, voltage, power, and energy (kWh) from the power source into the PDU. 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 PDU is configured with 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 improve Power Usage Effectiveness (PUE), a key metric for energy efficiency in data centres, and supports compliance with the EU Energy Efficiency Directive (EED).
Switched Outlets
This functionality allows connected IT hardware to be remotely powered on or off, enhancing flexibility and efficiency in data centre management. Utilising Near Zero Voltage Switching (N-ZVS) and Outlet Switching Delay, each outlet can be controlled with optimised performance while reducing electrical stress on the power infrastructure.
A remotely switchable PDU provides key benefits including:
Improved energy efficiency by powering down unused equipment
Reduced operational costs through fewer on-site interventions
Enhanced outlet-level power control
Increased availability via remote reboots during incidents
Supports compliance with EU energy efficiency regulations, including the Energy Efficiency Directive (EED)
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.
