For many years Rosenheim-based Heinzinger electronic has been offering expert services in top quality-superior, high-preciseness DC power supply Units. As a consultant in batteries and power electronics, it is also an active player in the e-mobility sector and many times is based on active front end systems from KEB Automation.
 
All trustworthy car manufacturers and suppliers across the world now depend upon on the bidirectional and regenerative automotive test systems inside Heinzinger’s ERS series. What’s more, its DC origins and drops for test benches are essential to the development, top quality assurance and EOL (end-of-line) evaluation of batteries and power electronics within the e-mobility field.
 
Network performance
KEB assures mains-compliant energy sources and recovery that matches Heinzinger’s high-precision DC controls. The sinusoidal flow in the serving regen modes provide the top likely power quality, with active power element correction even included as standard.
 
The hottest COMBILINE Z1 AFE filters are used to confirm exceptional mains-side electromagnetic compatibility of the systems. Together with the system’s added common-mode rejection capability, these filters present a stable and adjustable intermediate circuit voltage that offers as an interface to consumer electronics.
KEB’s rapid DC-bus control in the millisecond range allows even +/-100 per cent sudden load variations and pulse loads to be changed reliably.  What’s more, KEB also guarantees interference-free energy output on the hovering, short-circuit-proof DC output side with its COMBILINE EMC DC filters.
 
Heinzinger therefore enjoys the following benefits:
System solution for the universal DC energy supply
Sinusoidal currents for feeding and regen
Voltage stabilisation
Water cooling
Significant power range
Filters with common-mode rejection ability
EMC DC voltage filters
 
System solution
KEB grants power electronics and filter technology for the full performance range from 50 to 600 (1200) kilowatts. The key account here is water cooling capacity, as this avoids unnecessary ambient temperature increases and high priced air-conditioning systems – even in laboratory environments. Trusted water cooling solutions not only enhance process reliability but also result in significantly higher performance density.
