More and more charging columns for electric cars are being installed throughout Europe. Testboy developed the measuring adapter TV 900, in order to be able to test the type 2 charging columns standardized in Europe. The TV 900 takes over and simulates the communication with the charging column and an electric vehicle. An installation tester or a multimeter can be connected via the 4mm banana socket. Thus, testing with a VDE 0100 tester, such as the Testboy TV 455, is possible. The built-in LED indicates whether and how many phases are present. One of the three phases can be switched to the built-in Schuko socket. This allows each phase to be tested individually.This text is machine translated.
