During the strict aging test of the the module power supply production, the module power supply is generally operated at full load for a long time. How long is this "duration"? Generally 24 hours or 48 hours. Of course, in order to save costs, some companies shorten the aging time to 1 hour, and very few companies don't even age their products.   Aging test is also called baking machine or burn in machine, which means to test it harshly or "try to burn it". Only those products that have been tortured and survived are excellent products. Make sure that all power modules are aged at least fully 24 hours, and all indicators are fully tested before leaving the factory, so that users can rest assured, feel at ease, and feel at ease.
