AC/DC Desktop, Wall Adapters – GST120A20-P1M Application Field and Working Principle

The AC/DC Desktop, Wall Adapters – GST120A20-P1M is one of the most powerful and reliable wall adapters in the market today. It is capable of delivering up to 120 watts of power at a maximum of 20 Amps. With its wide input voltage range, it can be easily used with a variety of DC power sources, making it perfect for applications like telecoms, UPS, POE, industrial, medical, gaming, and marine applications. This wall adapter is UL/CUL cerified and has an operating temperature range of -20°C to +50°C.

The GST120A20-P1M is a switch mode DC/DC converter and operates in a buck converter mode. It is based on a two-stage topology, consisting of an input stage followed by an output stage. The input stage is essentially an inductor-capacitor filter, which converts the input voltage to a fixed, regulated voltage output. The output stage is a diode bridge, which is used to rectify the output voltage in order to convert it into direct current. The output voltage is regulated by a control circuit, which ensures that the output voltage is kept constant, regardless of the input voltage, thus enabling the adapter to maintain its rated output voltage at all times.

The adapter has a wide input voltage range of 90V to 336V AC, allowing the adapter to accommodate large variations in mains supply voltage. This ensures that the user does not experience fluctuations in the output due to voltage variations at the supply. The adapter also has an automatic over-current protection feature, which helps protect the adapter from short circuit or overload conditions. This feature also ensures that the output voltage remains stable in the event of such a condition.

The adapter also has a low output ripple and noise, providing high efficiency and reliable power delivery. In addition, it has a low inrush current feature, enabling it to be used in applications where current spikes may be an issue. Furthermore, the adapter is designed with active current sharing, allowing multiple adapters of the same type to be used in parallel to increase the available output power.

The AC/DC Desktop, Wall Adapters – GST120A20-P1M is a highly efficient, reliable, and user friendly power solution for a wide range of applications. Its high efficiency, low output ripple and noise, and low inrush current features all make it perfect for use in applications requiring a high level of performance. Its wide input voltage range also makes it a good choice for applications where multiple power sources are required. Additionally, this adapter can be used in applications that require multiple adapters to be used in parallel in order to increase the available output power.
