Working Principle

The LEP240F-48 works on the principle of switch-mode power supplies which convert AC power into DC power. This is done by a power conversion circuit that switches the AC voltage at high frequency and transforms it into a DC voltage.The converter uses switching transistors to rapidly switch the voltage at high frequency. This makes it possible to reduce the size of capacitors and other electrical components used in the power supply circuit, which makes the converter more efficient.The LEP240F-48 uses an innovative and efficient power conversion circuit which efficiently converts AC power into DC power. This is done by using a combination of insulated-gate bipolar transistors (IGBT) and high frequency power switches which switch at a maximum frequency of 250kHz.The IGBTs are used to switch the AC voltage to the DC output, and the high frequency power switches are used to create a low nuisance factor. The high frequency power switches also provide an efficient form of power conversion by providing a high degree of control over the power output.The LEP240F-48 also features an active EMI filter circuit which reduces the output voltage’s electro-magnetic interference. This ensures that wireless communications are not affected by the power supply. The converter is designed to provide optimal performance and is equipped with various protection features such as overvoltage, overtemperature and overcurrent protection to ensure reliable and safe operation. In summary, the LEP240F-48 is an AC/DC converter used in various industrial, commercial, and residential applications.
