Schurter Series 6610-5: IEC Appliance outlet type F for Intelligent PDUs and UPSs

Schurter Logo1.jpg

Schurter is launching its series 6610-5, the logical next step from the successful 6610 series; a new level of functionality is added to the industry’s original outlet popularly known for the highest level of efficiency during assembly.

- Integrated light pipes for status indication
- IDC Terminals
- V-Lock cord retention

6610-5 Series

The new 10 A-appliance outlet, series 6610-5, offers integrated guides for light pipes. It features up to two light pipes, intended to channel light from LEDs placed on a printed circuit board to the outlet surface. Technicians are able to clearly see which systems are working properly, or respond to required maintenance adjustments. The controls of the LEDs are freely configurable, wherein each state can be represented clearly and independently. To avoid damage and to make the wiring easier, the light pipes

can be inserted after the installation and need to be ordered separately of the sockets in the PDU.

The use of IDC connectors is particularly efficient. Multiple sockets can be wired quickly in a single step. This highly efficient way of wiring saves considerable time and thus labor costs. The phase contact is available with an optional PCB, quick connect or solder terminal for an independent line supply and status indication. To ensure an even better optical feedback, SCHURTER provides the individual outlets in black, white and grey.

The 6610-5 series is available in two arrangement versions, so called “along” and “cross”. Depending on the application and type of PDU, mounting several sockets vertically (cross) or horizontally (along) one behind the other can be achieved. The IDC terminals are then oriented accordingly for insulation displacement of the wires.

The new 6610-5 series offers a pull-out safety feature to prevent against unintentional removal of the power cord. Depending on the arrangement of the outlets in the strip – along or cross – the Schurter V-Lock or cord retention systems with side latches can be used. The snap-in mounting of the 6610-5 is designed for plate thicknesses from 0.8 to 3.0 mm. Additional versions to be launched in the near future will include 16 A appliance outlets.

Schurter DKIH-4: Ferrite and Nanocrystalline Chokes for 4-Wire Applications Mount On PCB

Schurter Logo1.jpg

DKIH-4

Schurter expands its wide range of current compensated chokes with new customer specific variants for 4-wire-applications on PCB. The new DKIH series is now available with ferrite or nanocrystalline ring core. The new product is designed for three phases plus neutral wire applications with rated currents from 10 A to 50 A. Due to its open design, the chokes are light weight and compact, ideally designed to suppress EMC noise caused by power applications on the PCB.

Like all other aspects of electronic design, the power portion is often built today using discrete components on printed circuit boards. With the trending integration of components, to achieve smaller and smaller form factors, thermal problems and high currents on the PCB can become a challenge. The resulting EMC interferences can affect adjacent modules because of the lack of spatial separation. Therefore, a compact filter on the circuit board with discrete components is often the best solution. A current-compensated choke with capacitors is the most efficient measure for the suppression of EMC interferences.

The DKIH-4 series is suitable for three phases AC and neutral wire applications from 10 A up to 50 A. The common mode chokes are also designed according IEC 60938 and are rated 600 VAC making them suitable for many applications such as UPS systems, switching power supplies, charge stations for electric vehicles and frequency converters for energy storage.

Schurter HCF Series, SMD Solid-State Fuse for the Most Demanding Applications

Schurter Logo1.jpg

HCF Series

Schurters’s new High Current Fuse, HCF, is an extremely robust SMD fuse, designed using solid-state / thin-film technology. The HCF is especially suited for use in particularly harsh applications, where the reliable interrupt of high currents is critical.

Schurters’s experience, acquired from the development of solid-state fuses for the space industry, and the cooperation with ESA, have led to the development of the HCF. The new HCF has a similar structure as the two ESA-certified types Schurter MGA-S and HCSF. Fuses used in Space applications meet the most rigorous performance requirements, with only the most advanced, most reliable technologies available. However, the intensive screening of each individual fuse, which is essential requirement for space applications, is not necessary with the HCF for non-Space applications. This leads to a substantial reduction in the cost per fuse.

Solid State / Thin Film Technology
In contrast to conventional fuses with a melting wire, the HCF has a metallic thin film layer. With this manufacturing technique, a metal layer is applied in conjunction with a so-called sputter. The two form on a glass substrate in an exact micrometer thickness. The resulting fuse element is enclosed with a ceramic housing, that guarantees the necessary stability and interrupt capacity. No harmful substances escape in solid or gaseous form during cutoff of the fuse. This technology also makes the SCHURTER HCF completely impermeable to potting compound, which can be used to achieve a hermetic seal e.g. for use in intrinsically safe applications according to ATEX and IECEx requirements.

High Breaking Capacity
The Schurter HCF has a high breaking capacity of up to 1000 A at 125 VAC resp. 125 VDC with fast response. It covers a rated current range from 5 A to 15 A.

Application Areas
Due to its robust design, the HCF fuse is particularly suited for applications which offer high reliability under particularly difficult conditions (thermal and mechanical shock, cycle endurance, etc.). Examples of possible applications: ATEX- and offshore oil and gas applications, equipment operated in sub-arctic regions, aviation electronics, and certain medical technology, where robust and space saving fuse performance is required. The temperature from -50 °C to 125 °C, as well as a vibration resistance – tested up to 1600g – make the HCF ideal for the most demanding high-performance applications under the most adverse conditions.

Finder Type 18.5K – KNX Presence and Movement Detector

Finder.jpg

A new technological product has been added to the range of presence and movement detectors of Series 18: this is the type 18.5K detector with KNX technology.

Type 18.5D

 

The new movement sensor uses the reliable and tested detection technology that already characterizes the previous Series 18 detector models and is suitable for applications in building automation systems featuring the KNX standard.

Technical features:
Specifically designed to sense micro movements, this sensor is the ideal solution for the management of lighting systems in offices and work environments in general and schools.

The sensor lens has been developed to obtain higher sensitivity in the detection of micro movements and guarantees two reading and sensitivity areas, identified as
•a movement area, which is larger and covers an area of 8×8 m;
•a presence area, which is more important for detecting small movements, and covers an area of 4×4 m.

The type 18.5K movement and presence sensor is provided with 2 software outputs, one of which is controlled according to the light measured by the internal sensor (this function can be disconnected), and is also appropriate for particular types of systems where it is necessary to control both the lighting and the heating/air conditioning.

There is also a third software output that sends only movement information to the KNX Bus: thanks to specific software inputs, sensors can be networked in Master/Slave configuration. This functionality is particularly suitable for controlling large rooms.

Accessories included in the package:
The detector is supplied complete with supports that can be used for ceiling or suspended ceiling mounting and is powered directly by the KNX Bus.
