75 years Gustav Klein On the occasion of the 75th anniversary of the Gustav Klein company, I would like to express my sincere thanks to all customers, business partners and employees for the many years of successful cooperation. In addition to its headquarters in Schongau, the company has had another production site in Austria since 1969. The complete product range can also be manufactured at our Inzing facility. Since its foundation in 1948 by Gustav Klein, the company has developed into a globally well-positioned manufacturer of power supply systems for industrial applications. In the meantime,...

Application 1: Testing DC charging stations For optimal performance and realistic testing of your EV charging systems, our I-TS is the perfect choice. The I-TS simulates the EV batteries for these tests. Integrate the I-TS into your test environment to ensure the reliability and safety of your products and reduce time-to-market. Test bench for charging technology • • • • • Fault injection Analyzer / Simulator DC fault injection Connection box Communication test Application 2: Multi-channel system with energy balancing via DC bus Our innovative multi-channel system MI-TS allows you to test multiple...

Application 3: Test bench for DC/DC converters When testing DC/DC converters, theDC DC channels of the (M)I-TS serve as a source and as a load. DC/DC converters with integrated galvanic isolation can be tested DCwith an MI-TS-3871 with 2 channels. For DC/DC converters without internal galvanic isolation, the I-TS-3872 or two separate I-TS-3870 are suitable for testing. Application 4: Test bench for batteries Due to the seamless transition between source and sink operation and the high dynamics, the (M)I-TS is suitable for testing batteries as a cycler or for the pulse power test. In the pulse...

Accessories for test and simulation systems Additional accessories are available to complement and round off our power supplies. PDSB (Power distribution switching box) PDU (Power distribution unit) Control cabinet for parallelizing several DC outputs or for switching a DC output to different test benches. Over 50 different variants are available. Control cabinet for local connection of the test object in the test bench. Additional capacitors and isolating devices can also be integrated here. 12 I High-performance test systems

Capacitor box Touch-proof housing with capacitors to stabilize the control loop. DCU (Discharge Unit) If the possibility of AC mains recovery is not sufficient, the Discharge Unit offers the possibility of using discharge resistors to reduce the energy of the device under test in the battery emulation.
