1. Basic performance, suction action voltage, release voltage, general purpose relay under no-load conditions, the suction action voltage, the release voltage should be consistent with the standard, rated voltage, five suction action voltage, the voltage of five. Universal relay contact voltage at rated voltage and rated current, contact voltage drop is less than or equal to 20 10mV / A.
2. Pressure resistance performance, the connection between the non conductive parts and the conductive part of the cabinet should be able to withstand 50Hz, 550V 1min sine voltage test, insulation without breakdown. When a large number of continuous production, the available voltage is 660V, the test lasted for 1 second.
3. The temperature resistance of the product, the universal relay can work according to your requirements, and will not be limited by the lower operating temperature.
The dynamic voltage and release voltage and the contact voltage drop of the general relay at room temperature after the storage temperature and the low temperature test 8h should meet the requirements. According to hoyle。 Temperature limits of the work requirements, and should limit the selection.
The dynamic voltage and release voltage and the contact voltage drop of the universal relay which is restored to room temperature after high temperature test 8h should meet the requirements.
4. Product temperature and humidity cycling performance, according to the provisions of the temperature and humidity cycling performance test, after the end of the test room temperature, relay contact voltage drop should be specified.
5. Vibration performance, in the case of the relay does not work, the installation part of the "other parts" requirements, should be carried out in the *, three direction sweep frequency vibration test, the general relay should meet the requirements. Post-48h salt spray test
The test voltage of the universal relay should be consistent with the requirements of the release voltage.
6. Salt fog resistance, general relay is not in the case of work, in the 48h after the salt spray test provisions, the general relay showing absorption dynamics.
