AC DC converters are electronic equipment that converts alternating current (AC) into direct current (DC). Yet, the efficiency of the conversion is not always 100%. This is where the LGA75A-48 comes to the rescue, providing a reliable high efficiency AC-DC converter.

The LGA75A-48 is a single-phase AC to DC converter module specifically designed for applications that require highly efficient operation. It is a compact, low profile, cost-effective solution ideal for integration into wide variety of products. It offers excellent input power factor correction and ultra-high efficiency, making it ideal for use in energy-star applications, as well as other applications requiring low power consumption.

At its core, the LGA75A-48 consists of a high frequency isolated DC/DC converter. This module requires only a single input voltage, while providing two regulated output voltages. It also features a robust electrostatic isolation of up to 24kVrms, providing superior protection from fluctuations in the power grid.

The LGA75A-48 is an isolated, low voltage, high efficiency AC to DC converter that operates with efficiency up to 96%. It is also capable of delivering high power output, with a maximum output current of 30A and up to 451W. It also has a wide input voltage range from 90 to 264VAC, making it well-suited for applications with global power input requirements. Additionally, it provides over current, over voltage and temperature protection.

In terms of working principle, the LGA75A-48 utilizes a step down converter, referred to as a flyback converter, to convert the incoming AC voltage to the desired DC output. It uses a transformer to step down the input voltage to a low voltage by using a bridge diode and a switching transistor. The current passes through the switching transistor at regular intervals and is used to drive the transformer. This causes an alternating current to flow through the transformer, which is then converted into a direct current at the output.

The LGA75A-48 is profiled for use in commercial and industrial applications, such as telecommunications systems, industrial PCs, test and measurement equipment, optical communications, meter measurement and many other applications that require efficient power conversion. Its high level of efficiency, wide input voltage range, and excellent power factor correction make it an ideal choice for energy-conscious and cost-sensitive applications.
