Application Note schurter.com/downloads Light pipe for status indication Light pipes in IEC device sockets for status indication in PDUs More intelligence is the watchword for power supply. Terms such as "Smart Grid" and "Intelligent Power Grid" are on everyone's lips. This development will permeate our everyday life. Especially when there are solutions that make this intelligence efficient and easy to use. SCHURTER offers a wide range of IEC appliance sockets for the installation of optical fibres. This allows the light from LEDs mounted on a printed circuit board on the back of the socket to reach the front of the unit. The light guides are always positioned precisely above the LEDs in injection-moulded guides. Suitable positions for the openings are the four corners of the outlet. For type F, the two corners on the side of the earth conductor are used. The direct integration of the light guide into the appliance socket has several advantages: The light indicator is located close to the socket. This means that the signal can be assigned quickly and unequivocally, even in large power cabinets with a large number of sockets and cables. Using intelligence more efficiently A typical application is the distribution strip for PDUs (Power Distribution Unit) in data centers. Some of them already have advertisements. However, these are usually located at the head end of the ledge. With the new SCHURTER appliance sockets, the available intelligence can be used more efficiently. The service technician on site can see directly which cans work and/ or where a problem exists. For example, a failure can be signalled by a red LED and a critical power consumption pattern by a yellow LED. This makes it possible to carry out repairs and preventive interventions faster, easier and more cost-efficient. Customized solutions The range of SCHURTER IEC appliance sockets with optical fibres is wide. The standard versions are equipped with light guides with a diameter of 2 mm and a length of up to 50 mm. They are designed for front panel thicknesses between 0.8 -3.0 mm. However, the name SCHURTER is synonymous with customer-specific solutions. Flexibility is high when it comes to the arrangement and size of the openings, the choice of light guide and its attachment to the box. Thanks to the extensive knowledge of standards and certifications of the SCHURTER development department, customer-specific adaptations and new developments including connection variants, mounting methods and optical feedback according to standard are possible. This enables the development of a safe, customer-specific device socket and PDU application. In order to ensure an even better differentiation of individual cans, various can types are not only available in black, but also in grey and white colour coding. This allows for a classification into the three-phase system, and in the often darker power supply shafts of the data centers, they thus offer a clear plus in terms of safety and functionality. ILSCHURTER ELECTRONIC COMPONENTS

schurter.com/downloads Efficient assembly and additional safety In addition to the strengths of the IEC appliance sockets with integrated optical fibre openings, the general advantages of the SCHURTER appliance sockets are mentioned. Various models have IDC (Insulation Displacement Connector) connections. With the rear protective cover, the three conductors can be pushed into the insulation displacement terminals at the same time, and the cover remains locked to the socket as a contact protection. This makes installation and wiring particularly efficient and costsaving. Up to now, IDC connections...
