For many years Rosenheim-based Heinzinger gadget has been offering expert services in advanced-excellence, maximum-preciseness DC power supply Units. As a consultant in batteries and power electronics, it is also an active player in the e-mobility area and commonly relies on active front end systems from KEB Automation.


All reliable car manufacturers and suppliers around the world now rely on the bidirectional and regenerative automotive test systems in Heinzinger’s ERS range. What’s more, its DC supply and sinks for test benches are critical to the development, quality assurance and EOL (end-of-line) screening of batteries and power electronics within the e-mobility sector.


Network performance

KEB ensures mains-compliant energy supply and recovery that fits Heinzinger’s high-precision DC controls. The sinusoidal currents in the feeding regen modes provide the best feasible power quality, with active power aspect editing even included as basic.


The newest COMBILINE Z1 AFE filters are used to ensure exceptional mains-side electromagnetic compatibility of the systems. Together with the system’s added common-mode rejection ability, these filters provide a stable and adjustable intermediate circuit voltage that operates 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 readjusted reliably.  What’s more, KEB also guarantees interference-free energy output on the drifting, 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
  • Large power range
  • Filters with common-mode rejection ability
  • EMC DC voltage filters


System solution

KEB comes with power electronics and filter technology for the full performance range from 50 to 600 (1200) kilowatts. The key consideration here is water cooling capacity, as this prevents unnecessary ambient temperature increases and overpriced air-conditioning systems – even in laboratory environments. Trusted water cooling solutions not only improve process reliability but also result in greatly higher performance density.
