Realisation
A system for use in process control requires high performance, real-time capability, data throughput, reliability and robust thermal properties, which were incorporated into the design of all system elements from the outset. Aspects such as cost-optimised production of the overall solution or investment protection through longevity were also taken into account.
The development objectives included very high computing power, parameterisable control and regulation hardware and the simultaneous operability of a large number of power modules.
Various challenges were faced in the project. One of these was to ensure complete signal integrity at all times with a high data transmission rate. This results in very high amounts of heat that need to be dissipated from the system. Thanks to an innovative ventilation concept, which was verified and optimised through extensive thermal simulations, an almost ideal uniform distribution of the flow speed per slot could be achieved even if one fan failed. The electronics development, the housing concept and the highly effective EMC shielding solution could be realised under one roof at HEITEC, which meant that the project could be implemented cost-effectively within the set time frame. HEITEC was also able to realise the development and production of the associated highly complex electronic assemblies in-house.
The unique combination of hardware, software, electronics and mechanics, internal synergies and expertise guarantees the customer a fast time to market as well as a technologically advanced, high-quality and cost-effective implementation of the desired solution without multi-partner management - taking into account possible follow-up costs. HEITEC's comprehensive services also include validation, testing, (re-)certification and longevity of supply guarantees.
