All news about GUDE
Active switched and metered PDUs generally refer to IP power distribution units that provide AC supply voltages. In the GUDE Systems portfolio, most power distribution units belong to this category.
Furthermore, remote power switches can also provide direct current (DC) supply voltages. This is especially interesting if consumers from the IT or AV area are to be connected to the IP power strip: Many of these end devices require an extra-low voltage of 5V, 12V or 24V and can be supplied directly by a DC PDU.
Particularly practical: The problem with the individual clunky power supply units of the end devices can then be solved.
The following is an overview of the reliable metered and switched DC PDUs available from GUDE. These have the features described above.
21-fold switched AC/DC PDU
This PDU has a switching function that can be used to switch connected devices on and off. 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 trouble-free operation of the PDU. Ideally, so-called high inrush relays are used here.
This PDU has a measuring function that can be used to measure the consumption of the connected devices. These can be measurements of electrical quantities such as voltage, current, phase angle, power factor, frequency, active, apparent and reactive power. The measurement of fault current, which is important for operational safety, can also be recorded. In addition, it is possible to configure limit values for the measured quantities, which, if exceeded, result in an immediate alarm via e-mail. There are three types of current measurement:
Unit-Metered PDU (input side)
The measurement is performed at the input or per bank of the PDU
Outlet-metered PDU (output side)
The measurement is made in relation to each output of the PDU, i.e. per connected load.
Inline-metered PDU (intermediate)
The measurement is made inside the PDU. It is placed before the distribution to provide passive PDUs with metering functionality.
