Problems solved by technology
Therefore, the current test method does not meet the test requirements according to the national military standard GJB1515A
For the product, the number of groups is large and the distance between the pins is relatively close. Short circuit phenomenon is extremely easy to occur during the test (some are high-voltage products, which are very dangerous during manual testing), resulting in product burnout, and the manually built circuit is prone to misalignment. , falling off, accidental touch phenomenon, causing safety accidents; based on the above factors, a device that can directly test the contact voltage drop is needed

The invention discloses a solid state relay power consumption testing device, which comprises: a current collection and processing module used for collecting the input end current and the output end current of each group of contacts of a to-be-tested solid state relay, and carrying out analysis and processing on the collected current; and a voltage collection and processing module used for collecting the input end voltage and the output end voltage of each group of contacts of the to-be-tested solid state relay, analyzing and processing the collected voltages and then displaying the analyzed and processed voltages. According to the testing device provided by the invention, current and voltage of the input end and the output end of the contact of the to-be-tested solid state relay are collected through the current collection and processing module and the voltage collection and processing module and are displayed after being analyzed and processed, so that collection, processing and display of the current and the voltage of the input end and the output end of the contact of the to-be-tested solid state relay are realized, and the probability of safety accidents in the contact voltage drop acquisition process of the alternating-current solid relay is greatly reduced.
Description
technical field [0001] The invention belongs to the field of electronic appliances, in particular to a solid relay power consumption testing device. Background technique [0002] In the test items of solid state relays, it is necessary to test the power consumption of the product. The current test method can only test one group at a time. According to the national military standard GJB1515A, multiple groups must be tested at the same time, and cannot be tested separately. Sometimes repeated tests are required. Data consistency is not guaranteed. Therefore, the current test method does not meet the test requirements according to the national military standard GJB1515A. For the product, the number of groups is large and the distance between the pins is relatively close. Short circuit phenomenon is extremely easy to occur during the test (some are high-voltage products, which are very dangerous during manual testing), resulting in product burnout, and the manually built circui...
