RPC-1.35

Complementing its standard HV connector portfolio, Rosenberger develops and manufactures customer-specific high-voltage components for electric and hybrid vehicles. These enable the lowest possible transition resistances, ensuring long-term low-loss performance and reliability in critical electrical systems such as those for battery charging, cell management, heating, and air conditioning. From concept to final delivery, Rosenberger high voltage custom components are the perfect fit every time. Using its component toolkit, including PDUs, Y-splitters, Busbars and Cell Modules, Rosenberger can develop and manufacture a wide array of tailor-made solutions. These are designed and configured precisely to the relevant vehicle architecture, allowing ideal combinations of the various fuses, relays and other passive and active components required. Power Distribution Units (PDU) Power distribution units (PDU) for vehicles have multiple power input and outputs and use all kinds of connectors, fuses, and relays. In these cases, the PDU generally forms the central link between the vehicle power electronics and batteries, electric motors, and other ancillary units. Y-Splitters Y-splitters are used to distribute the power from one cable harness to two or more units, e.g., between a DC/DC converter and an electric air-conditioning unit. Rosenberger can design Y-splitters for applications with and without shielding for cable cross sections from 4 mm² to 95 mm² in collaboration with the customer. Cell Module Connectors The Rosenberger HV portfolio also includes cell module connectors. These connectors are required to link battery modules within a battery pack. For typical battery applications, multiple custom-designed battery connection points are required. Based on the robust pressure contact system, Rosenberger offers cell module connectors without flexing parts in the contact area. Systems from 100 to 350 A are available. Different assembly directions, coding variants as well as cross sections can be implemented according to customer-specific requirements.

Rosenberger’s High-Voltage Test & Measurement Solutions deliver deep insights into the EMC behaviors of high-voltage Automotive Traction Networks. Using our powerful HV measurement coupler, dedicated calibration software and calibration kits, EMC experts can perform RF voltage and current reliability calculations with absolute precision. HPK Measurement Coupler The newly developed HV Measurement Coupler for HPK series from Rosenberger enables a minimally invasive testing method for measuring the reliability of RF voltages and currents. In conjunction with a dedicated calibration process, patented algorithms accurately calculate the RF currents and voltages in the calibration reference plane. Furthermore, due to the minimal invasion techniques deployed by the coupler there is no risk of impairment to harness performance when under test. The watertight and robust design also means testing can be carried out under any environmental conditions. HPK Calibration Kit Although the HPK measurement coupler includes calibration data, an optional HPK calibration kit is also available. Combined with the RCTD software it enables customers to manage their own calibration requirements themselves. A set of all necessary calibration standards is provided and a description for the acquisition of calibration files is included in the RCTD user manual. Rosenberger recommends 12-monthly calibration intervals and offers a recalibration service to HPK coupler customers if required. RCTD Software Rosenberger Calibrated Time Domain Software (RCTD) was developed to enhance EMC-related, automotive high-voltage measurement capabilities. Within the RCTD Software, the time domain data captured by an oscilloscope using the high-voltage coupler is post-processed to calculate high frequency currents and voltages at the given calibration plane within the high-voltage power train. Therefore, calibration data is created and taken into account before measurement occurs. Delivered on a USB-stick in a sturdy wooden box, the RCTD Software includes the functions to create calibration data and post process the measurement data on a PC or directly on LeCroy HDO oscilloscopes for real-time evaluation. The software can be also used for any other directional coupler.

Based on the SMA connector standard, Rosenberger QMA connectors are designed for applications up to 18 GHz. The quick-lock mechanism enables easy and reliable connections in the tightest of spaces – primarily in mobile base stations – and 10 times faster compared to SMA offerings. Packing density is also superior to SMA due to the minimum pitch and toolless connection, dispensing with the need for torque spanners for fastening coupling nuts. Rosenberger offers QMA as standard version and with plastic quick-lock mechanisms in four different color codings. QMA is not intermateable with SMA.

Rosenberger HVR®50 connectors are available in straight and angled variants. The additional slide locking mechanism (CPA – Connector Position Assurance) prevents accidental disconnection. Despite their small size these connectors achieve a current capacity of approximately 60 A at 85 °C. HVR®50 connectors are mainly used in ancillary units such as electrical heating systems, air-conditioning units, DC/DC converters, and for charging batteries.
