power adapter 12V3A 12V4A ac/dc desktop adapter

    12V3A Desktop Power Adapter and 12v3a Switching Power Supply are widely used. 12V3A Power Adapter is widely used in notebook power supply, integrated LCD display, face recognition instrument, LED light bar, plant lamp, massager, beauty instrument and other equipment, which are closely related to our life. Therefore, it is very important to choose a safe 12v3a Power Adapter. How to choose a qualified 12v3a desktop power adapter? First of all, it depends on the certification he has passed. Second, it depends on the internal materials. Third, it tests various parameters: conduction, radiation, text wave, withstand voltage, static electricity, lightning stroke, high voltage, shell temperature, etc. Third, look at the appearance., Mingxin power supply 12v3a power adapter has passed the global certification, and is iec62368 + iec61558 double standard certification CB, UL FCC CE GS ukca, SAA c-tick, RCM, PSE, KC, KCC, BIS, safety-mark, PSB, vi6 energy efficiency, etc. We do it safely according to the certified materials and will never cut corners. The adapter shell is made of pure PC 94v0 grade, environment-friendly and fireproof materials. Moreover, our conduction and radiation margin are above 5dB. We have a professional R & D team, which can help customers rectify safety regulations for free. Our power adapters are aged for 2 hours each, with high voltage of 3300v 3S, air discharge of 8Kv, contact discharge of 4KV and lightning stroke of 1KV. We have our own laboratory, including roller, ESD electrostatic gun, conduction tester, hot wire tester, ball pressure, plug force tester, salt spray tester, high and low temperature constant temperature and humidity box and other machinery and equipment. Each series of products are pre production and in production, there will be professional sampling inspection and reliability test to ensure quality.
