16、349-301:20064 1 Scope This standard specifies a method for testing the pick-up voltage and drop-out voltage of relays and contactors. It shall be used together with EN 2349-100. 2 Normative references The following referenced documents are indispensable for the application of this document. For date

17、d references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 2349-100, Aerospace series Requirements and test procedures for relays and contactors Part 100: General requirements 1)3 Pick-up (actuating) volt

18、age 3.1 Mounting method The relay or contactor shall be wired in accordance with EN 2349-100. 3.2 Test procedure The coil shall be left in a de-energized state for 30 min before starting the test. The minimum rate of voltage increase and the time to energize the coil, applicable to the device under

19、test, shall be determined to prevent overheating of the coil. The rated voltage shall be applied to the coil, then reduced to zero, and gradually increased until the relay or contactor picks up. The contacts shall not change their switching position when the voltage is increased from the pick-up vol

20、tage to the maximum operating voltage. An indicating device shall be used to determine the position of the contacts. For qualification tests, the relay or contactor shall be tested in each of two directions along three axes which are perpendicular to each other (i.e. six degrees of freedom). 3.3 Tes

21、t criteria The relay or contactor shall pick up at the rated voltage specified in the product standard. 4 Drop-out (release) voltage 4.1 Mounting method The relay or contactor shall be wired as described in EN 2349-100. 1) In preparation at the date of publication of this standard. EN 2349-301:20065

22、 4.2 Test procedure The coil shall be left in a de-energized condition for 30 min before starting the test. The rated voltage shall be applied to the coil and then gradually reduced until the relay or contactor drops out. The contacts shall not change their switching position when the voltage is red

23、uced from the drop-out voltage to zero. An indicating device shall be used to determine the position of the contacts. For qualification tests the switching device shall be tested in each of the three axes which are perpendicular to each other. 4.3 Test criteria The relay or contactor shall drop-out
