What is an Inline Energy Meter (energy monitoring for existing server racks)?

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• PDUs with outdated intelligence are still in use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

What does an Inline Energy Meter do?

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

When do you need an Inline Energy Meter?

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• intelligent PDUs are technically outdated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

Who is an Inline Energy Meter for?

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.

Inline Energy Meter vs Metered PDU: what is the difference?

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.

Upgrade existing PDUs with modern energy intelligence

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.
