An extension lead, also referred to as multiple socket or extension leads, provides a power supply connection for several electrical devices with standard plug connection.
This gives you the possibility to supply a large number of electrical devices. Extension leads are available with illuminated on/off switch, child protection, overvoltage protection, master/slave function and many other features. In order to be able to use the application in the best possible manner, diverse extension leads are also suitable for assembly.
Extension leads with overvoltage protection:
These multiple sockets are able to protect your devices from faults in the power supply, such as overvoltage, indirect lightning strikes or circuit noise.
Master/slave extension leads:
These extension leads feature a practical automatic switching system with master/slave function which works as follows:
When the device which is plugged into the red master socket is switched on/off, all devices in the slave sockets can automatically be switched on and off as well.This multiple extension lead is suitable for anyone who wants to be comfortable and simultaneously wants to save power.
Extension leads with on/off switch:
The safety switch of the multiple socket is illuminated and can be switched on/off in a bipolar manner.
What are overvoltages?
Overvoltages are all voltages that temporarily surpass the threshold value of the mains voltage. Without effective protection, the overvoltages destroy sensitive electronic components in the circuits of the connected appliances.
What are the reasons for overvoltages?
The most dangerous causes are very high voltage peaks caused by indirect lightning strikes. Power surges also get into the power supply with immense power by means of indirect lightning strikes or reach computer systems, video equipment and Hi-Fi equipment via the telephone and aerial cable and destroy these devices,if they are not adequately protected.
Why is overvoltage protection so important?
Protection from overvoltages and electromagnetic current peaks can be achieved by using overvoltage protection extension leads which are used between the power supply (socket) and the device. They make sure that dangerous overvoltages are discharged to the ground in a matter of seconds and thus, the connected devices are protected.
Which extension lead for Hi-Fi and TV?
In general, all extension leads for TV and Hi-Fi systems meet their target. They supply the device with power. Nevertheless, the importance of technically high-quality cable connections is often underestimated. The gain in sound quality thanks to an anti-interference power extension lead is often amazing and not related to the price class of your Hi-Fi components. Due to the fact that upstream, more than x metres of a simple ribbon connector are connected from the house distributor to your socket, which cannot be changed, enormous interference results, e.g. humming of the power amplifier, the speakers, occasional clicking and clacking sound in the playback. So if you have a source of interference and the cause cannot be remedied or realised, the only solution that remains is an output strip with integrated filter and overvoltage protection. Upstream filters at electronic devices are able to considerably increase the transmission capacity. So that perfect protection of Hi-Fi systems from power failures, power fluctuations or overvoltage damage is guaranteed.
Which extension lead for PC?
A multiple socket strips helps you to supply the devices at the workplace such as PC or printer with power. Apart from that, there may also be speakers, telephone, external hard disks, etc. The socket strip should in any case have enough sockets and also an integrated overvoltage protection. This provides protection from voltage peaks which even occur at great distances from the point of impact. The on/off switch serves your comfort. When not used, it can easily be switch off completely and thus, power can be saved. Here, master/slave socket strips are perfectly suited. As master device, you can for example use a computer which integrates slave devices such as monitor, sound system, printer, scanner, etc. into the automatic control.
Extension leads with USB
You generally make a distinction between a USB hub and USB charger. But what exactly is the difference between hub and charger? In addition to the sockets, type A ports are offered, as well; they serve the connection of USB end devices such as keyboard/mouse, printer, USB stick and USB hard disks and can thus be elegantly connected. Meaning that these USB ports only allow for “distribution”, not for charging.
The power supply of the USB hub is realised by means of the connection to a PC and/or a notebook using the type B socket. If you want to use the USB hub without connecting it to a computer, you need an external 5V power supply unit.
Table extension leads and retractable extension leads offer special comfort
The multiple sockets which are directly placed at and on the table not only offer the desired power distribution and, upon request, a USB charging function, they also provide special comfort. They offer a practical possibility to directly connect electronic devices without having to look for a free socket under the desk. If this extension lead is additionally equipped with a USB connection, you can, for example, also charge your smartphone or power bank. The power connection can be comfortably separated using an on/off switch.
The innovative permanently installed table socket for flexible workplace design can be lowered into the table plate and discreetly fits into the table surface. The extension lead is suitable for the workplace, the kitchen or also your home work station. An integrated USB connection is a special feature.
Extension leads for mounting
There are definitely many possible applications for extension leads. On the one hand, there are sockets strips with a simple on/off switch, with practical hand/foot switch or also extension leads which can be controlled via remote control or app - for special comfort. Extension leads have not just been lying on the floor around the household for a long time. Some extension leads are suitable for mounting on the wall or table. That’s exactly the reason why our product range includes sockets strips which are equipped with a 4-point support for perfect fastening, e.g. at a wall. However, if you prefer an assembly without screwing or drilling, you will also find the suitable extension lead. For this purpose, we have a very special fastening system. An intelligent, removable assembly plate for easy and straightforward fastening on the back side of the extension lead. Just take out the SB flap by slightly pressing the snap lug. By rotating the plate by 180° and re-engagement on the extension lead, the assembly openings are positioned correctly for the assembly. Additional practical flaps for the assembly with Velcro, cable tie & co. are located at both end pieces on the back side.
It goes without saying that safety in general takes topmost priority. For this reason, the child protection in our extension leads is also very important for us. Young children are very curious and tend to try out things they cannot already know that they are dangerous. The child protection of our extension leads (in the form of a cover) thus prevents small or pointed objects from getting into the socket.The small flap is only removed if both pins of the connector are inserted. If a child tries to push an object or the finger into one of the holes, this is prevented by the flap. In this way, we are able to increase safety at home. The RCD circuit breaker serves as mobile electrical accident protection between socket and device. It instantly disconnects the active conductors from the mains as soon as residual currents occur. Protection type IP44 means that the device is protected from foreign bodies and splash water.
Explained in brief:
IP= International Protection
4= (first indicator) Protection against solid foreign bodies
4= (second indicator) Protection against water
In some areas, the number of sockets cannot be large enough. Especially at a workplace, for example, you need a socket for the computer, the monitor, the sound system, the printer, etc. In this case, it does no harm to buy an output strip with a lot of sockets. It will then only be annoying if the number of sockets is enough, the supply line, however, is too short. For this reason, we offer extension leads with different cable lengths from 1.5m to 5m. The choice of the perfect extension lead is, of course, dependent on the type and application.
It should be said in advance that you should generally not connect extension leads one after another. This must (according to VDE 0620) even be noted on the extension lead by means of the “do not connect one after another” warning. Of course, a multiple socket has many advantages. On the other hand, it offers multiple connection possibilities for several devices; on the other hand, it serves as a kind of extension cable and can therefore be used flexibly. However, the maximum power of approx. 3,500 Watt must still not be exceeded at one extension lead.
In case of overload, it may already heat up to up to 200 degrees after few minutes and in the worst case even start a so-called “smouldering fire”. A smouldering fire differs from a normal fire in that there are no visible flames. A fire of this kind is particularly dangerous as it cannot easily be identified. In order to prevent this, you should calculate exactly how many devices can be connected at an individual socket strip. The relevant power of the device can be found on the so-called “type plate”. A sample calculation and more information are available here: https://www.brennenstuhl.com/blog/en/how-not-to-connecting-socket-strips-one-after-another/
