AC DC Converters

The LEA75F-48 DC power converter is a DC to DC converter designed to convert an input AC voltage into a regulated DC voltage. It is typically used in applications where a constant DC voltage is required to power a system or a device, such as in the automotive, aerospace, computer, and telecommunications industries. The DC output voltage can be set to any range from 0 VDC to 48 VDC.

Working Principle

The LEA75F-48 DC power converter uses a forward converter topology to convert an input voltage into its regulated DC output. The input AC voltage is rectified to an intermediate DC voltage, which is then feed into a buck converter that boosts the voltage to the desired output level. The buck converter is a closed loop system that continuously monitors the output and adjusts the duty cycle of the switching components to ensure that the output voltage remains regulated, even when subjected to changes to the load or input voltage.

Safety Features

The LEA75F-48 DC power converter is designed to provide isolation between the input and output, and features established safety features such as over and under voltage protection, overload protection, and short circuit protection. It is also UL approved for UL60950, and comes in a plastic case making it perfect for applications where safety and convenience is a priority.

Applications

The LEA75F-48 DC power converter is suitable for many applications that require a reliable and regulated DC voltage. It can be used as a battery charging circuit, a dc/dc converter, in inverter applications, or as an isolated output power source. The wide input voltage range and adjustable output makes it an ideal choice for mobile or portable applications that have varying power requirements. Additionally, theLEA75F-48 can be used to provide reliable backup voltage when the main AC power source fails. In summary, the LEA75F-48 is a reliable and versatile DC to DC power converter that is suitable for use in a variety of applications that require a regulated DC voltage. It is a compact and efficient device that provides isolation between the input and output, and features various safety features such as under and over voltage protection, overload protection, and short-circuit protection. Additionally, the adjustable output and wide input voltage range makes it an ideal choice for applications that have varying power requirements.
