AC/DC converters are used to transfer power from an alternating current (AC) to a direct current (DC). The LGA75A-12-S is a compact AC/DC converter with complete functions, which is used to convert AC to DC with high efficiency.

The operating frequency of LGA75A-12-S is 250KHz, the input voltage range is 90-264VAC and the input current is up to 8A. It adopts the latest synchronous rectification technology to improve the efficiency of the converter. This converter provides a variety of output power. The output voltage range is 12V, and the rated output current is 7.5A.

The main features of the LGA75A-12-S include the following: over current protection (OCP), over temperature protection (OTP), and over voltage protection (OVP). Its operating temperature range is from 0℃ to 40℃ and the working environment should be free from humidity. Moreover, it has a low-noise design and its behavior is compatible with RoHS.

The LGA75A-12-S is suitable for many applications, such as alarm systems, UPS systems, telecom power supply, LED lighting, data networking, automotive electronics, consumer electronics, and industrial automation. Its working principle is simple. The AC voltage is first converted into DC voltage, and then it is converted into a constant voltage and current with the input of transformer.

The internal components of LGA75A-12-S mainly consist of a transformer, a rectifier diode, a power switch, a filter capacitor, and a control circuit. The transformer can convert the AC voltage into a lower voltage. The rectifier diodes then rectify the alternating current into highly filtered direct current. Then, the power switch will convert the direct current into a constant DC voltage and current. The filter capacitor will filter out any residual AC signals to help maintain the DC output stability. Finally, the control circuit will regulate the output voltage and current.

The LGA75A-12-S AC/DC converter has a wide range of applications. It can be used to realize the DC conversion of products and systems in a wide range of fields, such as automotive, telecommunication, industrial automation, and other high-tech fields. It is a high-performance, compact and cost-effective solution for many applications.
