AC Power Sources, Frequency Converter
MAC-01, -02, -03
-
For reliability, all models of the Titan AC Power Sources/Frequency Converters are fully current limit protected against either continuous or transient short circuit or overload conditions. When an overcurrent condition exists, the internal current control loop overrides the voltage control loop and scales back the sinewave drive until it sees a safe output current level.

Doppler Radar Target Simulators
-
Automotive radar sensors play a vital role in the current development of autonomous driving. Their ability to detect objects even under adverse conditions makes them indispensable for environment-sensing tasks in autonomous vehicles. As their functional operation must be validated in-place, a fully integrated test system is required. Radar Target Simulators (RTS) are capable of executing end-of-line, over-the-air validation tests by looping back a received and afterward modified radar signal and have been incorporated into existing Vehicle-in-the-Loop (ViL) test beds before. However, the currently available ViL test beds and the RTS systems that they consist of lack the ability to generate authentic radar echoes with respect to their complexity. The paper at hand reviews the current development stage of the research as well as commercial ViL and RTS systems. Furthermore, the concept and implementation of a new test setup for the rapid prototyping and validation of ADAS functions is presented. This represents the first-ever integrated radar validation test system to comprise multiple angle-resolved radar target channels, each capable of generating multiple radar echoes. A measurement campaign that supports this claim has been conducted.

Back Plane Tester
-
This machine is used to test back planes used in telecommunications central stations. An operator loads a completed point to point wired back plane onto a retractable shelf on the front of the tester. Table continues and the disk falls through a hole into the bin. The shelf is pushed back into the machine where it is held in place by pneumatic operated clamps. Then a series of pneumatic cylinders sequentially insert a test card into each location in the back plane. A remote instrument performs a complete point to point continuity, short and hi pot test on all connections in the back plane.

Loop / PFC Testers

PeakTech Prüf- und Messtechnik GmbH
The PeakTech 2715 is a loop tester which is used to test the safety of electrical systems. These device measures the impedance of the short-circuit loop between the outer conductors of a circuit, whereby the probable short-circuit current is calculated. The protection of the circuit (miniature circuit breaker) must therefore trigger at a lower current than the expected short-circuit current, in order to avoid excessive heating of the lines and thus a fire risk. The PeakTech 2715 is due to its function and its robust design almost indispensable when performing new installations, but also for general checking of electrical systems, this device is the ideal companion.

Dual Loop Master Controller
-
The Xcite System Master Controller provides all dual loop functions needed for accurate closed loop control and display of the static and dynamic test variables, while producing the highest electro-hydraulic frequency response. At the heart of each Xcite System is the Master Controller, a compact electronic control package which provides all of the controls and displays necessary to operate a controlled force or torque exciter system. The Xcite Master Controller is unique in that it provides electro-hydraulic excitation over a broad frequency range, unprecedented by any previous electro-hydraulic excitation system. It achieves its great frequency range through the use of sophisticated circuitry, high voltage inputs to the servovalve and compression control of the dynamic feedback variable in addition to the conventional servo control of the static loop. Static parameters such as force or displacement may be matched with dynamic control variables such as force, displacement, velocity, acceleration or strain for maximum test flexibility.
