SOSA™ Aligned Technology
Building on OpenVPX, the standard defines a comprehensive architecture that supports modular system design while ensuring seamless component integration and interoperability across platforms.
Within this framework, Kontron Hartmann Wiener GmbH develops high-performance SOSA™-aligned components, including backplanes, power and management solutions, and system-level building blocks for next-generation embedded computing platforms.

SOSA™ Aligned BACKPLANE
High-speed performance and great flexibility characterize the SOSA™ Aligned backplane developed by Kontron Hartmann Wiener GmbH. As a central connection element, the backplane plays a key role in the overall system performance. Designed for compute-intensive applications, it is equipped with ample power reserves and based on a high-speed architecture supporting up to 100 Gigabit Ethernet.
The backplane’s high-speed performance of 100 Gbit/s has also been verified in independent tests.
With seven slots, the backplane enables the integration of a wide range of functionalities. Based on customer input, extensive experience, and in-depth analysis, the experts at Kontron Hartmann Wiener GmbH have defined a specific configuration, which can be modified and adapted to customer-specific requirements at any time.

SOSA™ Aligned DEVELOPMENT CHASSIS
The SOSA™ Aligned Development Chassis was developed based on both aesthetic and functional design criteria. Its open architecture provides optimal access to the installed backplane, supporting efficient handling and evaluation. A key highlight of the chassis is its cooling concept: up to ten high-performance fans are integrated to ensure sufficient cooling for virtually any board configuration. In addition, the chassis offers a high level of flexibility in use and is equipped with an extremely powerful power supply.
The development chassis is optimized for the 7-slot SOSA™ Aligned backplane from Kontron Hartmann Wiener GmbH, while also supporting the use of other backplane configurations. It primarily addresses two target groups: VPX board manufacturers who require a system environment for testing their boards, and system integrators who assemble and validate complete systems from multiple boards.
State of the Art Power Technology
VPX POWER SUPPLY
The VPX360 SOSA™ Aligned power supply is the latest generation within the VPX power portfolio and is specifically designed to meet the requirements of modern, high-performance SOSA™ and OpenVPX systems. It is a commercial off-the-shelf (COTS), conduction-cooled, ruggedized 3U VPX power supply delivering up to 600 W total output power, while fully complying with ANSI/VITA 62.0 and fitting into the standard mechanical envelope defined by VITA 46.0.
Designed for compute-intensive military and aerospace applications, the VPX360 features a single-stage wide input voltage architecture supporting nominal 28 V and 48 V DC, with an extended input range from 12 V to 70 V DC. The SOSA™-aligned power architecture provides a 12 V centric output configuration with additional 3.3 V auxiliary power, enabling efficient power distribution across modern VPX payloads.
High efficiency is achieved through state-of-the-art switching power technology, reaching up to ~88 % at full 600 W load, without the use of wet electrolytic capacitors. An embedded microcontroller enables advanced monitoring and control via dual I2C interfaces, supporting VITA 46.11 IPMI-compliant power management for system-level supervision and diagnostics.
The VPX360 is mechanically realized as a 3U × 5HP (1.0″ pitch) conduction-cooled module and is designed for operation with wedge-lock heat sinks and VITA 62 power backplanes. It integrates comprehensive protection features including reverse polarity protection, over- and under-voltage protection, over-current protection, over-temperature shutdown, and surge protection.
The power supply is designed in compliance with MIL-STD-461F (EMI), MIL-STD-704F, and MIL-STD-1275D, making it suitable for harsh electrical and environmental conditions encountered in defense and aerospace platforms.
Earlier VPX power supply variants such as the VPX340 (400 W) and VPX336 (360 W) remain available for lower-power VPX and OpenVPX systems. However, the VPX360 SOSA™ Aligned 600 W power supply represents the most advanced solution in the portfolio, addressing the increasing power demands of next-generation SOSA™ architectures.
VITA 46.11 Chassis Manager
Operating as software on the SOSA™ Aligned Development Chassis, the Chassis Manager complies with VITA 46.11. It is responsible for implementing functions to manage the entire SOSA™ sensor system. These functions include state detection, configuration, control, monitoring and logging, fault handling, testing, diagnostics, and safety management.
The Chassis Manager performs these functions both when the system is operating (in-band) and when it is offline or malfunctioning (out-of-band). The Chassis Manager communicates with all components in the chassis and with higher-level units in the operating environment. It collects information about the operating status, temperature, and the type, number, and condition of the installed cards.
LIGHTWEIGHT ATR
ATR (AIR TRANSPORT RACK)
THE MOST RUGGED PACKAGING FOR COMPUTING
The Air Transportation Rack (ATR) is the de-facto standard form factor for aircraft board electronic equipment since more than 50 years. The two ARINC drawings SK-141-10 and the SK-141-17 with detailed critical dimensions and tolerances for the initial 3 basic form factors, via the ½, 1 and 1 ½ ATR became the basis for ARINC 404A as it is used even today.
100GBase VPX Technology
Kontron Hartmann Wiener GmbH continues to push the boundaries of high-speed VPX technology. Advanced routing methods, designed for stable signal transmission at frequencies of up to 12.5 GHz, enable 100-Gigabit Ethernet on SOSA™ Aligned backplanes.
This high-speed performance has also been successfully validated in independent testing at the HARTING Corporate Technology Services laboratory, which is certified according to DIN EN ISO/IEC 17025:2005.
