All news about GUDE
Within active PDUs, a distinction can be made between switched (switching per output) and metered (measuring on the input side) PDUs. These power strips are also often referred to as intelligent PDUs or smart PDUs. Switched and metered PDUs are power solutions that switch each individual output and measure detailed current on the input side. Read more detailed information on these terms.
Protect your IT and AV installation with GUDE’s reliable and intelligent power distribution units from GUDE. These switched and metered PDUs have both a switching function and a detailed measurement function.

A switched PDU has a switching function in which connected devices can be switched on and off individually in each socket. This makes it possible to switch devices on and off in isolation in order to identify any problems that may occur. In addition, electricity costs can be reduced by switching off individual sockets if a connected appliance is not needed.
An integrated watchdog enables an automated and fail-safe switching sequence (self-healing function). The quality of the integrated switching relays plays a key role in the fault-free operation of the PDU. Ideally, so-called high inrush relays are used here.
A metered PDU has a measuring function that can be used to monitor the consumption of the connected devices in the individual sockets. The measured data can be accessed remotely to calculate electrical quantities. The functions vary depending on the model, but metered PDUs generally measure the following electrical variables:
In addition to the electrical parameters, a metered PDU can also measure the residual current, which is important for operational safety. Users can define limit values with additional functions to recognise threshold values. These threshold values automatically send an alarm to the user, for example by e-mail, to inform them immediatley time if they are exceeded. There are three types of current measurement:
There are three types of current measurement:
A unit-metered PDU monitors the power of all connected devices at the PDU infeed, i.e. at the input or per bank. The unit-metered PDU is always used in data centres or IT environments to monitor and measure the total power consumption.
An outlet-metered PDU monitors the power at each individual socket on the power distribution unit. There, the outlet-metered PDU monitors the power consumption of all individual connected devices and recognises trends in power consumption. This enables administrators to recognise whether they can reduce energy costs and comply with energy guidelines.
An inline-metered PDU measures the power consumption between the power source and the connected devices. Inline-metered PDUs monitor and manage both individual devices and device groups to visualise power consumption.
