An Inline Energy Meter is a standalone intelligent energy meter installed between the power supply and a PDU to measure the energy consumption of a server rack.
It is the ideal solution when:
• existing PDUs do not provide energy measurement
• PDUs with outdated intelligence are still in use
• racks should remain unchanged
• energy insight is required without replacing hardware
An Inline Energy Meter measures input-level energy consumption of a server rack.
In practice:
• the Inline Meter is installed upstream of the PDU
• it measures current, voltage, power and energy
• the existing PDU continues to distribute power
The Inline Meter:
• does not replace the PDU
• does not switch outlets
• adds modern energy monitoring to existing installations
An Inline Energy Meter is the right choice when:
• Basic PDUs are already installed
• intelligent PDUs are technically outdated
• racks should not be replaced or reconfigured
• energy data is required for reporting or compliance
• fast insight is needed with minimal disruption
Common use cases include:
• existing data centres
• colocation racks
• enterprise server rooms
• retrofit projects
• phased upgrades
The Schleifenbauer Inline Energy Meter is used by:
• data centre operators
• IT teams with existing infrastructure
• colocation providers
• facility managers
• system integrators
It is particularly suitable for organisations looking for energy monitoring without replacing PDUs.
| Feature | Inline Meter | Metered PDU |
| Power distribution | ✖ | ✔ |
| Input energy metering | ✔ | ✔ |
| Outlet-level metering | ✖ | ✖ |
| Retrofit existing racks | ✔ | ✖ |
| New PDU required | ✖ | ✔ |
An Inline Energy Meter is a retrofit solution, not a replacement for a PDU.
Many data centres still operate:
• Basic PDUs
• older intelligent PDUs
• PDUs without modern communication options
With an Inline Energy Meter, you can:
• keep your existing hardware
• gain up-to-date energy insight
• make racks ready for current monitoring requirements
All without major infrastructure changes.
Like all Schleifenbauer products, the Inline Energy Meter is:
• configured to match your power connection and load
• suitable for single-phase and three-phase applications
• supplied with the correct connectors
• available in any required quantity
Configuration is included at no extra cost.
The Inline Meters are available in the following electrical configurations:
Thanks to in-house production, Schleifenbauer offers:
• short lead times
• flexible adjustments
• consistent quality
Ideal for retrofit and expansion projects.
Choose an Inline Energy Meter if you need:
• energy monitoring for existing server racks
• a retrofit solution without replacing PDUs
• reliable input-level energy measurement
• flexibility without a fixed product portfolio
The Schleifenbauer Inline Energy Meter adds energy insight where replacement is not an option.
Inline Energy Meters are often searched for as:
• server rack energy monitoring
• retrofit energy metering PDU
• measure power consumption server cabinet
• rack-level energy measurement
• power monitoring for existing racks
