Customer profile

  • Application: Battery simulation and testing, powertrain, engine and electric motor test beds
  • Industry: Automotive
  • Country: Austria

Customer case

  • A leading manufacturer of battery test systems for electric and hybrid vehicles was looking for a reliable specialist with proven expertise in direct-current switching and controlling.
  • Design-in guidance, technological know-how and problem solving as well as the fulfillment of normative requirements were very important factors for the customer.
  • Schaltbau is a specialist in direct current and customer specific solutions with decades of experience in development and manufacturing.

The customer relies on DC contactors from Schaltbau for different applications such as transmission and powertrain test beds, battery simulation and testing, engine and electric motor test beds.

The main advantages of our DC contactors are:

  • High bi-directional current breaking capability and excellent isolation parameters
  • Very low contact resistance, low heat dissipation and high current carry capability
  • Robust „contact tip “ design, which means lowest probability of „stuck on“ failure
  • Components with very high electric life/endurance, switching under load and short circuit simulation without contacts welding
  • Aux. contacts for safe feedback loop acc. to IEC 60947-4-1, Anex F or IEC 60077
