CUSTOMIZED Industry: Electrical industry Testing system for power strips with a maximum of 12 Schuko sockets Task It was necessary to develop a testing system to automatically test the power strips with different numbers of sockets, which are positioned differently and also have different functions (e.g. master-slave). Solution Testing system for power strips | EN | 08.2016 Subject to change and error. In order to test the large number of different DUT, a test hood was used, in which up to twelve socket adapters with interchangeable head can be used for different types of connectors and can be flexibly positioned. It is also possible to integrate an actuator for the power strip switch. The test hood will be developed and supplied by the customer. After closing the test hood, automatic contact is established between one and twelve sockets via pneumatic cylinders. During the test, the switch integrated in the power strip can be automatically actuated via two additional cylinders to check the function of the switch. The protective earth conductors of all sockets, the high dielectric strength and function are tested. Moreover, a load is connected to the first socket of master-slave power strips to check the switching on of additional sockets. The easy-to-use PC software allows storage of an arbitrary number of test programs, so that the necessary scope of testing and the test data can be adjusted for each DUT. However, for products with similarly mounted DUT, it is also possible to use the same test program, which is then allocated to the respective DUT over the product list. By coding in different parts of the DUT contact, it is checked with the software whether the settings of the test hood match with the selected test program. The test results are automatically stored in XML or Access format. A separate test dummy is used to check the functionality of the testing system. The testing system does not allow further testing without a passed dummy test. Advantages ++ Turnkey solution including DUT support, adaptation and workplace design ++ Simple, intuitive operation for semiskilled personnel ++ The DUT needs to be connected only once, then the whole test process occurs automatically ++ In network operation, all test data is automatically saved at the specified location / database ++ Long service life and service-friendly design ++ All values and settings can be made using software ++ Automatic dummy test ++ Workplace safety according to EN 50191 ++ Simple retooling for a large number of different DUT types Specifications • Continuity test 24 V • Protective earth conductor test 10 A - 30 A at the 12 PE terminals of the sockets and the housing • High voltage test 5.5 kV AC / 2.99 mA and 6.0 kV DC / 3.99 mA (safety-current-limited) • Insulation test 6 kV DC • Function test single-phase to check all connections and the master-slave function • Switch actuation SPS electronic GmbH Blätteräcker 18 | 74523 Schwäbisch Hall | Germany | Tel. +49 7907 / 878-0 | info@spselectronic.com | www.spsel
