Shurter 4710-5 Series, 16 A IEC Appliance Outlet Type J for Intelligent PDUs and UPSs

Schurter Logo1.jpg

* Integrated light pipes for status indication
* IDC terminals for quick assembly
* V-Lock cord retention
* Color coding for easy identification in multiphase systems

With the appliance outlets of the 4710-5 series, SCHURTER launches the logical evolutionary step to the successful 4710 – with a clear plus in functionality for status indication.

The new 16 A appliance outlet series 4710-5 offers precisely fitted, integrated guides for light pipes. Up to four light pipes can be used to channel LED light from the circuit board. The feature provides a space and cost saving approach to status indication in PDUs, which are used to signal the equipment technician regarding system status. The operation of the LEDs is freely configurable. To ensure proper application, the light pipes must be ordered as an accessory and should only be inserted into the power distribution unit after the sockets have been mounted and wired.

The use of IDC terminals is particularly efficient. Several outlets can be wired quickly and reliably in a single process step. This highly efficient form of wiring significant reduces assembly time and cost. For individual power supply and status indication, the phase contact is designed as a PCB connection. On request, this terminal can also be offered as quick connect or solder terminal. SCHURTER offers the 4710-5 outlets in black, white and grey for multiphase distinction.

The 4710-5 series is available in two versions: “along” and “cross” to the pin axis. Selection depends on the design of the PDU and the arrangement of the outlets, vertically (along) or horizontally (cross) one behind the other, thereby properly orienting the wires to the direction of the strip. To avoid unintentional power cord disconnection, the new outlets offer the V-Lock cord retention system. The snap-in mounting of the 4710-5 is designed for panel thicknesses of 1.0 to 3.0 mm. Standard versions are available in 1.5 and 2.0 mm.

Technical Data / Approvals
* Appliance outlet Type J (C19) acc. IEC 60320
* IEC/EN 16 A / 250 VAC; 50 Hz
* UL/CSA 20 A / 250 VAC; 60 Hz

Schurter MGA-A 1206 SMD Fuse with 125 VDC

Schurter Logo1.jpg

* No tin whiskers, no tin dendrites
* Lead-free coating (RoHS conform)
* Similar fuse qualification as in MIL-PRF 23419
* Hermetically sealed and robust construction

Schurter extends its successful MGA / MGA-S line of 1206 dimension SMD ceramic fuses with an aviation version that is tin whisker free and completely dispenses with leaded coating.

Crystalline tin dendrites and tin whiskers pose a considerable risk of short circuits in highly dense electronics. Dendrites form during the electro-deposition process, whereby heavy marks could appear on the fuse end caps or housing. A thorough inspection and cleaning is required according to MIL-PRF 23419. Tin whiskers form after the electro-deposition process. The cause is not well understood, although adding lead to otherwise pure tin soldering is commonly used as a preventable measure.

However, lead has become an unwanted element according to many environmental initiatives, e.g. RoHS directives. For this reason, Schurter has extended the successful SMD thin-film fuse family MGA with the new –A variant. In addition to the classic MGA and the ESA-certified MGA-S space fuse, the aviation version, MGA-A, uses gold alternatively to lead. Gold plated end caps provide a surface where neither whiskers nor dendrites can form. This makes the new MGA-A a safe solution for use in not only highly sensitive electronics in the aviation industry but often suffices for use in the industrial grade space sector.

The technical design is similar to that of the ESA-certified MGA-S. This means: hermetically sealed, ultra-robust construction, which is ideally suited for use in intrinsically safe applications according to ATEX and IECEx requirements. Despite its very small footprint (1206), the MGA-A has a particularly high breaking capacity of up to 300 A at 125 VDC and can be used in a wide temperature range of -55 °C to +125 °C.

The new MGA-A from Schurter is suitable for all applications where the highest demands are placed on reliability and availability.

Schurter Type DD12 Compact Power Entry Module with Filter

Schurter Logo1.jpg

* Very compact design
* Various mounting options
* Variants with ground choke
* V-Lock cord retention
* Fuseholder meets latest IEC standard#

Schurter extends its successful power entry module series DD12 with new variants for screw and snap mounting. New versions are also available with additional ground choke for suppressing high-frequency interference on the ground conductor. The DD12 with fuse holder, switch and filter offers remarkable functionality in a very compact housing.

The DD12 filter series combines an IEC C14 appliance plug with a 1- or 2-pole fuse holder, a 1- or 2-pole switch and a high-quality mains filter. The particularly wide metal flange (horizontal or vertical) make contact with the housing surface over a large area and thus enables an optimum filter and shielding effect.

Ground Choke
The DD12 series is now available with a ground choke. In addition to the current-compensated choke on the pole and neutral conductor, the line filters have a second choke on the earth conductor. The ground choke is located between the device plug and the filter output. Placing the filter directly at the mains input ensures that possible high-frequency interference currents on the earth conductor cannot bypass the filter via the housing. The versions with medical filters (no Y capacitors) especially benefit from improved asymmetrical attenuation in the higher frequency range due to the earth line choke.

Applications
The DD12 series is available with standard or medical filter. It is suitable for use in devices that require a particularly high immunity to interference. These include IT or telecom systems according to IEC 90650-1 and medical devices according to IEC 60601-1.

The series meets the new fuseholder requirements outlined in IEC 60127-6 for enhanced fire safety and is also suitable for use in home appliances according to IEC 60335-1. It is compatible with V-Lock retaining cordsets.  The DD12 series is certified for currents up to 10 A/250 VAC according to IEC standard and 8 A according to UL/CSA standard at 125/250 VAC. It is ENEC and cURus approved.

Schurter – Two Are Better Than One

Schurter Logo1.jpg

More and more devices on the power grid must function smoothly without interfering with each other. Not so easy, since switching power supplies and highly clocked integrated circuits are used in almost all electronic devices. EMC filters can help here. Where necessary in multi-stage design.

In practice, it is quite possible that the attenuation is not yet sufficient despite the use of a filter. In such cases, several filter stages optimized for the specific interference signals are then connected in series. Which in interaction significantly improve attenuation in both differential and common-mode interference. Usually you get very good results with a doublestage filter. However, triple-stage filters are also conceivable, feasible and available.
