GUDE Introduces New Power Distribution Units

Published 5th March, 2021

GUDE Systems GmbH has launched a series of power distribution systems for professional installations. The switchable power outlets are integrated into sturdy metal housings and are suitable for horizontal installation in 19-inch cabinets (1 height unit). They have 6 IEC C13 load outlets or 6 load outlets with safety socket on the front. Connected devices can be switched on sequentially and off in reverse order by an automatic switching routine. Pressing the switch on the front of the device triggers a 15-second switching sequence, which switches the individual sockets one after the other with a delay of 3 seconds each. These delay intervals between the switching operations can be increased individually to up to 60 seconds if required.

The Sequencer is also available in variants with integrated overvoltage protection (type 3) and mains filter. The overvoltage protection prevents defects on the device and on connected consumers, while the mains filter minimizes interference noise on connected loudspeakers or amplifiers.

The power sequencer 8112 avoids voltage peaks that occur due to high inrush currents when several loads are switched on. When switching off sequentially, sudden abrupt changes in current in the supply line are prevented from causing faults in the circuit. The device helps prevent tripping of the upstream fuse in the supply.

The power strip is used, in audio/video installations with a power amplifier. The audio amplifier is connected to the last load output. The PDU ensures that the amplifier is switched on last after the other components. When switching off in reverse order, it is switched on first, before the other components. The otherwise occurring banging noises, which can also damage loudspeakers and amplifiers, are avoided. The user can connect an external pushbutton to the jack connector on the front to trigger the switching sequence from outside the 19-inch cabinet.
