The smaller the power adapter, the higher the requirements for conversion efficiency and heat dissipation. The 220 volt alternating current is transformed, rectified, filtered, and stabilized to output a device suitable for electrical work power. The exquisite workmanship and compact design of the power adapter are widely used in humidifiers, air purifiers, electronic refrigerators, ED lamps, security, LCD TVs, digital products, monitoring equipment, etc.
mainly has the following four characteristics:
One, a strong R&D team, as well as independent R&D centers and laboratories; focus on safety R&D and production, and R&D results 5W-180W power supplies have been put into the market;
2. Using microelectronics technology and advanced manufacturing technology, high precision, low noise; multiple protections such as overvoltage, overcurrent, overcharge, short circuit, etc.;
3. Obtained CB, CE, UL, KC, GS, FCC, CCC, SAA, PSE and other safety certification certificates, with stable performance;
Four. The internal use of high-quality power chips, the application life is doubled, the external use of high temperature and fire-resistant ABS+PC plastic structure is strong inside and outside, high quality and longer use
General manufacturer power adapter reliability test items
The product test and inspection of the power adapter reliability test equipment of general manufacturers include:
1, high temperature test (high temperature operation, high temperature storage);
2, low temperature test (low temperature operation, low temperature storage);
3, high and low temperature alternating test (temperature cycle test, thermal shock test);
4, high temperature and high humidity test (damp heat storage, damp heat cycle);
5, mechanical vibration test (random vibration test, sweep frequency vibration test);
6, mechanical shock test;
7, wire swing test;
8, pin salt spray test;
9, EMC testing, etc.
