ELECTRICAL CONNECTOR

摘要

The invention relates to an electrical connector (1) for connecting an electrical device to an electrical conductor (3) for powering the electrical device with DC voltage. The electrical connector comprises a diagnostic information providing unit for providing diagnostic information about a connection between the electrical device and the electrical conductor and an indicator for indicating the determined diagnostic information. An installer can therefore readily see whether the electrical connection is correct or not. Accordingly, the installer can modify the electrical connections such that the indicated determined diagnostic information indicates a correct electrical connection. This reduces the likelihood of a shutdown of the powering of the electrical device with DC voltage, after the installation has been completed.

主权项

1. An electrical connector for connecting an electrical device to an electrical conductor for powering the electrical device with DC voltage, the electrical connector comprising:
a diagnostic information providing unit for providing diagnostic information about a connection between the electrical device and the electrical conductor, and an indicator for indicating the determined diagnostic information wherein
the diagnostic information providing unit is adapted to determine diagnostic information being indicative of at least one of: polarity correctness, power availability, power losses, correctness of voltage level, and whereinthe electrical conductor is electrically connected to a DC voltage source, which is adapted to be switched off, if an overload condition is detected,the diagnostic information providing unit is adapted to check whether a 0 V condition is present on the electrical conductor, after an electrical load has been applied to the electrical conductor, the load corresponding to the power requested by the electrical device to be connected by the electrical conductor, and to determine the power availability based on whether the 0 V condition is present.
