ME40A1802N01

ME40A1802N01 is an AC DC Desktop, Wall Adapters which is widely used in many applications. It is capable of delivering an output of up to 40W/50W/60W/80W and is an ideal choice for charging applications, such as mobile phones, tablets, laptops, etc. The ME40A1802N01 utilizes a PWM (Pulse Width Modulation) to regulate the output voltage and current. This PWM controller allows the adapter to provide a constant output voltage and current regardless of the input voltage and load conditions. The PWM requires an external feedback circuit, an optocoupler, which compares the output voltage with an adjustable reference voltage. The optocoupler will then turn on and off the switch mode power supply resulting in a constant output voltage and current.The ME40A1802N01 also utilizes an EMI (electromagnetic interference) filter. This filter is used to reduce the level of EMI generated by the power supply. This EMI filter reduces the input current ripple, thus resulting in a more efficient operation and less load on the system that the adapter is being used in. This also eliminates unwanted noise generated by the system.The ME40A1802N01 features an over-current protection (OCP) circuit. This OCP circuit monitors the output current and when the current exceeds the rated maximum, the power supply will shut down and remain in shut down mode until the current returns below the maximum. This ensures that the power supply always operates within its specified limits and does not damage the system that is being powered.The ME40A1802N01 also features an overload protection (OPP) circuit. This OPP will detect if the output current exceeds the maximum and will shut down the power supply until the load is brought back within specified limits. This feature helps to prevent overloading of the power supply and prevents damage to the device powered by the adapter.Finally, the ME40A1802N01 is RoHS (Restriction of Hazardous Substances) compliant. This ensures that the power supply is free of any hazardous materials, and can be safely used in any environment.Overall, the ME40A1802N01 AC DC Desktop, Wall Adapters is an efficient and reliable power source for a wide variety of applications. It is capable of delivering up to 40W/50W/60W/80W of output and utilizes a PWM and EMI filter to ensure that the output is consistent and efficient. It also features OCP and OPP circuits to ensure safety and prevent damage. In addition, it is RoHS compliant and can be safely used in any environment.
