Schurter DKIH-EVB Evaluation Boards for Current-Compensated High-Current Chokes

Schurter Logo1.jpg

• Development tool for 1- and 3-phase systems
• Suitable for DKIH-1 and DKIH-3
• For high power applications

Schurter is now offering proven test circuit boards for the DKIH-1 and DKIH-3 high-current chokes. With these, an EMI filter circuit for 1- or 3-phase systems can be set up and tested easily and quickly in an iterative process without having to make any adjustments to the layout of your own PCB.

Every developer of an electrical or electronic device is faced with the same problem: In the end, the device must comply with international EMC guidelines regarding emission and immission. Problems, often of an unpredictable nature, mostly arise in the power section. Like most electronic assemblies, the power section is increasingly being mounted on printed circuit boards using discrete components. A compact filter directly on the printed circuit board with discrete components is therefore usually the best solution. And a current-compensated choke with capacitors is the most efficient measure for EMC suppression.

DKIH-EVB
With the new SCHURTER DKIH-EVB (Evaluation Board) test circuit boards, a wide variety of filter configurations can be quickly calibrated with the DKIH series of current-compensated chokes without making any changes to an existing PCB layout. With high L and C values, the vast majority of disturbances can be adequately attenuated. The art of filter design, however, lies in finding an effective and at the same time cost-optimized combination of components. Often, slightly smaller L and C values are sufficient if these are perfectly combined. An EMC measurement of the finished system or device is indispensable for the declaration of conformity.

Schurter Thermal Fuse RTS Now Also Available With Shunt

Schurter Logo1.jpg

• Protects power semiconductors from thermal runaway
• Integrated current measuring sensor (shunt)
• SMD reflow solderable up to 260 °C
• Meets requirements according to AECQ

Schurter’s RTS thermal fuse, successfully launched in 2018, gets a new variant with an integrated shunt. The RTS is a particularly compact overtemperature protection device for power semiconductors in SMD technology for highest demands.

RTS stands for Reflowable Thermal Switch. It was developed to protect highly integrated power semiconductors from overheating. Prior to mechanical activation, the new thermal fuse can be soldered on conventional reflow soldering machines with profiles up to 260 °C.

Minimal Footprint
The new overtemperature protection device comes in the same minimal dimensions and maximum breaking capacity despite its additional shunt functionality. On its small 6.6 x 8.8 mm footprint the RTS can handle operating currents of up to 130 A and rated voltages of up to 60 VDC.

Integrated Current Measuring Sensor (Shunt)
The shunt version has an integrated resistance with particularly low temperature dependence. This resistance, known as a shunt, enables precise current measurement and enables an additional – non-thermal – circuit protection, e.g. via a controller.

Protection Against Thermal Runaway
Thermal runaway refers to the overheating of a power semiconductor due to a self-reinforcing, heat-producing process. One of the reason is the trend towards increasing power density and miniaturization of electronic circuits. The RTS protects these power semiconductors against thermal runaway. In such an event, the thermal fuse reliably interrupts the circuit at a precisely defined temperature as a fail-safe device.

Schurter GP21 / GS21: 400 VDC Connector System According to IEC TS 62735-1

Schurter Logo1.jpg

• First IEC connector system on the market for 400 VDC according to TS 62735-1 (2.6 kW)
• Designed for PDU and UPS in Data Center
• Various terminal options
• Safe disconnect under load

With the GP21 plug connector and the GS21 socket-outlet, SCHURTER launches the world’s first UL approved IEC TS 62735-1 standardized DC connector system designed to enable efficient DC power distribution in data centre power distribution strips and UPS.

 

With a complete DC power supply architecture, from source to load, the cost-intensive and failure-prone transformations and conversions, including their components, are completely eliminated. Operational reliability increases with improved efficiency.

In the digital age, vast quantities of DC-powered devices are in use: consumer electronics, industrial IT, communications technology, and electric vehicles to name a few. New technologies are beginning to emerge to enable direct current at the source of supply, which in turn is driving the establishment of standards.

 

Direct current improves the quality of the power being supplied. Problems with harmonics and harmonic distortions are eliminated. Phase compensation is also not necessary. Furthermore, coupling synchronization to different sources and networks is no longer necessary.

IEC TS 62735-1
The new standard for DC power distribution up to 2.6 kW requires a more complex design. The Connector system must be designed considering the potential for arcing associated with disconnecting the DC power supply. The permissible temperature range of the connector pins is -5 °C to +105 °C. An additional interlock for arc protection, while hot plugging, is not required for the version up to 2.6 kW.

Plug GP21 / Socket-Outlet GS21
The re-connectable SCHURTER GP21 plug accommodates a cable cross-section of between 0.75mm²/18 AWG and 1.5 mm²/16 AWG. The corresponding socket-outlet GS21 is designed for front panel thicknesses of 1.5 mm or 2.0 mm. Quick Connect 6.3 x 0.8 mm or PCB terminals are available for the connection.

Outlook
The reduction of steps to convert power resulting in less power loss, clearly speaks to the need for the use of DC power supply in data centres.

IEC TS 62735-2 is in process for the standardization of a higher DC power requirement of up to 5.2 kW. The appropriate interconnect with the necessary safety interlock (cold switch) are currently being developed.

To increase operational safety, SCHURTER will also be equipping its 2.6 kW plug with a cord retaining system. Appliance-side DC components, such as inlets and cord connectors, are being standardized in IEC TS 63236. This standard is currently in the draft phase and is expected to be published by the IEC in 2021.
