GPM40-5G

AC/DC converters are devices that convert alternating current (AC) power into direct current (DC) power. The GPM40-5G is a low noise, high frequency AC/DC converter that can be used in a variety of applications. This article will discuss the features and working principle of the GPM40-5G as well as its application fields.

Features

The GPM40-5G is a miniaturized, high-efficiency AC/DC converter suitable for sensitive electronic equipment that requires very low ripple and noise. It has an input voltage range of 90 –260VAC, and an output voltage of 5VDC, which can be adjusted ±10%. It meets the international radio interference requirements for a material of class B and the safety standard of IEC-60950-1.

The GPM40-5G has a high efficiency (up to 91%) and is designed to allow a high power density, a high power factor, and a total harmonic distortion of less than 0.5%. It has an adjustable switching frequency, allowing the output voltage to be easily adjusted depending on the application. It has built-in over temperature, over current, and short circuit protection, making it a reliable power source.

Working Principle

The GPM40-5G is a switching power supply. At the input, AC voltage is converted to DC by a rectifying diode following a filter circuit. The DC voltage is then rectified and controlled by a switching MOSFET/IGBT, reducing the current consumption at the input and increasing the efficiency of the converter. The switching frequency is adjustable, allowing the output voltage to be adjusted according to the application. The output is then regulated using a linear power regulator or a switching power supply.

Application Field

The GPM40-5G is suitable for use in a variety of applications, including the automotive, consumer electronics, medical, industrial, and computer industries. It can be used in charging systems, solar panel systems, LED lighting systems, and many other applications. It is an ideal power source for sensitive electronic equipment, as its low noise and high-efficiency makes it well-suited for use in noise-sensitive environments.
