Although many applications are configured such that the current is not drawn until after full engagement of the con

33、ibliography. 4 Preparation of specimen Each specimen shall consist of a mated connector with its terminations. Specimens shall be conformant to the relevant IEC connector standards. Each free connector and each fixed connector shall be terminated with 3 m (max.) of the maximum conductor size cable f

34、or which it is intended to be terminated, according to IEC 61156 series. For each specimen, all of the circuits (mated contacts) shall be wired in parallel, as given in IEC 60512-9-3, and all of the circuits shall be tested (see Figure 1). If necessary, a printed circuit board may be used which shal

35、l not influence the test results. 5 Test circuit requirements 5.1 General The values for the circuit components and the details of the test circuit, referenced in IEC 60512-9-3, shall be as shown in Figure 1. 6 1 2 3 4 5 IEC 1098/12 Key 1 Cables in accordance with 4.1 2 Connector under test 3 Induct

36、or 100 H 4 Variable resistor (e.g. 50 to 300 ) 5 Capacitor 5 F 6 Power source NOTE 1 Only one circuit of the connector under test, as referenced in IEC 60512-9-3, is shown for clarity. Items 1, 3, 4, 5, and 6, are replicated for each circuit (engaged contacts) of the connector. Item 6 may be single

37、or multiple. Each circuit of the specimen shall be wired in parallel with the other circuits of the specimen, and all circuits of each specimen shall operate simultaneously. NOTE 2 The variable resistor(s) are used to adjust the current(s) to the specified value. Figure 1 Test circuit details 5.2 Vo

38、ltage and current The variable resistor(s) shall be set so that the electrical current in each circuit (mated contacts) of the specimen is 0,6 A. When specimen is unmated, the open circuit voltage, in all circuits, shall be 55 V d.c. See Annex A. IEEE 802.3 at specifies a maximum current of 0,3 A pe

39、r conductor and an open circuit voltage of 55 V d.c. The test current has been doubled to 0,6 A in order to represent the high BS EN 60512-99-001:201260512-99-001 IEC:2012 7 probability that one contact of any given pair will separate before the other. Therefore as in the cited application, where cu

40、rrent is carried by pairs of contacts in multiple parallel circuits, the last contact to break will do so carrying all the current (twice the nominal). 5.3 Auxiliary equipment The test laboratory may choose to use switches to reverse polarity. However, use of such switches shall not influence the te

41、st parameters. 6 Tests and test schedule 6.1 Test group UEL 1 A minimum number of 8 specimens shall be prepared for this group; then tested according to Table 1.
