Schurter UHP Series SMD Fuse for High Currents

March 28, 2023
Schurter Logo1.jpg

Safe Tripping of High-Energy Overcurrent in SELV Voltage Level
• Very high breaking capacity of up to 3000 A
• Safe tripping in 15 s at twice the rated current
• Operating temperature range from -55 °C to 125 °C

With the increased availability of low-cost, high-performance lithium-ion battery cells, there is a growing need to manage higher and higher currents via low-cost, SMD-assembled PCBs.

The dedicated Schurter UHP fuse with rated currents of 50 to 100 A ideally meets the requirements for high breaking capacity and fast tripping in the event of overcurrents by galvanically separating these immense energies stored in Li-Ion batteries in a controlled manner.

Market Situation
With the success of the smartphone, Li-Ion batteries have gained enormously in importance. They are also the key to the success of the even more energy-intensive electric cars, which rely on this very technology. The price per kilowatt hour of a Li-Ion battery pack has fallen to a tenth in the last decade!

Power ∼ Current2
The higher the current on a PCB, the more power must be converted and also dissipated. It is therefore particularly important for such applications to have a reliable fuse that is capable of galvanically separating the circuit in time in case of an overcurrent. The UHP fuse developed by Schurter especially for this purpose disconnects the circuit at twice the rated current within a maximum of 15 seconds and ensures that the circuit board can be built more economically and in a space-saving manner.

High Energy Short Circuit
Li-ion batteries are capable of storing very high amounts of energy and releasing it again within a very short time - for instance in the event of a short circuit. The low internal resistance of the cells can lead to short-circuit currents of up to 3000 A, depending on the configuration. The UHP fuse is built so robustly that it can withstand such high currents at the SELV (Safety Extra Low Voltage) voltage level of up to 63 VDC, and even at 80 VDC it can still provide a performance of up to 2000 A.

Extreme Temperature Range
The UHP is designed to operate at ambient temperatures from -55 °C to +125 °C. This makes it ideally suited for applications in the automotive sector, but also for other applications with potentially large temperature variations.

E-T-A CPC12 ControlPlex® System

July 25, 2022

Unrivalled Uptime in Machine Construction and Process Control

Requirements regarding product quality and stability of the production process are constantly rising in machine construction and process control.  The CPC12 ControlPlex System offers permanent data logging, analysis and processing.  This provides the required transparency to detect any changes in the production process at an early stage and to take countermeasures in time.

Consistency of the systems is particularly important.  Besides the field bus interfaces PROFINET and EtherCAT, the CPC12 bus controller also has another Ethernet interface. It allows access to the system even without fieldbus.  Direct access to the integral web server of the device is made possible.

All data and information are available on the device on site, but also in the office.  If the circuit protector has tripped, it can quickly be reset to operation.  Downtimes are reduced and machine uptime is increased.  Data can easily be analysed and evaluated later by means of remote access.

The modular REX system is especially adapted to the special requirements of machine construction and process control. The CPC12 bus controller extends the REX system by the connection to different fieldbus connections.  This makes your DC 24 V power distribution and protection more transparent than ever.

The REX12D electronic circuit protector records status and measuring values of each load circuit and transmits them to the bus controller.  System operators and maintenance staff thus receive all information they need to detect changes and possible undesirable developments at an early stage.
