The test of high power UUTs requires specialized expertise and test techniques to ensure the safety of the test developer and the end user.

In the Mass Transit sector typical LRUs requiring this type of test approach include Propulsion, LVPS and Inverter LRUs. Each has their own special requirements and physical size; The weight and the potentially lethal voltages and currents involved all have to be considered both during the handling and testing of the units.

S500 test solutions have been developed to provide a safe physical and electrical environment with safety interlocks helping to ensure the protection of the operator – especially when high voltage or high current is present.
