☷ Product Description
The 9V1A/12V1A/15.5V1A/9V2.5A switch type adapter, which meets the VI level energy efficiency standard, is widely used in consumer electronics, security monitoring and other fields due to its strict energy efficiency control and stable output characteristics. Common core characteristics （1） Energy efficiency and power consumption control The VI level energy efficiency standards (DoE VI in the United States and CoC V5 in the European Union) impose strict requirements on the full load range efficiency and no-load power consumption of adapters: the average efficiency needs to reach 89% or above (for products with output voltage>5V and power ≤ 49W), for example, a 12V1A adapter with an efficiency of ≥ 85% and no-load power consumption<0.1W at 115V/230Vac input. The key technologies to achieve this indicator include: topology optimization: using quasi resonant (QR) mode to reduce high load switching losses, combined with frequency reversal (FFM) and burst mode, suitable for light load and no-load scenarios; Component upgrade: using low static current controller and synchronous rectification technology to reduce conduction losses; Circuit optimization: Simplify peripheral design (such as omitting optocouplers and TL431), improve EMI characteristics through frequency jitter technology, and reduce auxiliary circuit power consumption. （2） Electrical performance and reliability Wide input and stable output: AC input range coverage, compatible with global power grids; Output voltage adjustment rate ± 3% – ± 5%, ripple voltage<120mV (such as 12V1A adapter no-load ripple<) 120mV@90Vac ）Ensure stable operation of sensitive equipment; Multiple protection mechanisms: Built in overvoltage, overcurrent, short circuit, and over temperature protection. Some models (such as 9V1A) also have anti starting shock and anti electromagnetic interference capabilities, complying with FCC CLASS B/EN55022 CLASS B electromagnetic compatibility standards; Durable design: Equipped with a 94V-0 fire-resistant plastic shell, the primary and secondary insulation withstand voltage reaches 3000VAC, the working temperature range is -25 ℃ -+40 ℃, and the MTBF (mean time between failures) exceeds 30000 hours (under full load conditions of 25 ℃). （3） Universality and Compliance Interface and specification customization: The DC head specifications support multiple sizes such as 5.5X2.1mm, 3.5X1.35mm, and the wire length can be customized (0.5-2m) to adapt to different regional plug standards such as European, American, and British standards; Some models have been certified by UL, FCC, RoHS, etc. and comply with UL1310 safety regulations (UL file number E310452)
