Safety meets competence

Testing system for PDUs (power distribution units) with up to 24 outlets

Testing system for continuity, ground bond and hipot tests for several 19'' MPH PDUs.

Industry: electrical industry

Task

The task was to examine the variety of different power distributors at a test station. Both the number of outlets (24 pieces), and the different types of outlets must be contacted and checked. The different types of outlets from the connector plug should be examined.

Solution

Using a sophisticated switching matrix, the various outlets and their number can be safely tested. By means of sensors, it is checked whether all outlets have been contacted and checked against the DUT data stored on the network after the DUT was identified by the bar code. The various connection options can be tested using a variety of adapter cables. Ground bond and hipot tests are performed following the continuity test of the terminal / connector to the various outlets. Each connection line to each outlet is checked here. The safety of the testing personnel is ensured by a safety light curtain.

An arbitrary number of test programs can be stored in the testing system PC. This allows the customer to independently write new test programs while developing new products. However, for products with identical data, it is also possible to use the same test program, which is then allocated to the respective DUT over the product list. The test results are stored automatically in XML or Access format on an arbitrary place on the network.

A separate test dummy is used to check the functionality of the testing system fully automatically. During the daily start of the testing system, the testing personnel is asked to connect this dummy and start the corresponding program. The testing system does not allow further testing without a passed dummy test.
