AC-DC converters play a pivotal role in the modern world of electronics and their application fields span across almost every industry. One such AC-DC converter is the QGKF-240-24, which combines an array of features and benefits that make it suitable for a vast range of purposes. This article will examine the application fields and working principles of the QGKF-240-24.

The QGKF-240-24 is primarily used in electrical engineering and industrial automation applications. It is designed for both standard and advanced applications, and offers a reliable and reliable power supply. The device is capable of operating from a wide input voltage range ranging from 115V to 230V AC. The output voltage of this AC-DC converter is 24V DC with a working power ranging from 4.8W to 7.2W, and the efficiency can reach 92%. The unit is designed to meet EMC standards, with a built-in frequency compensator that can automatically sense the input frequency and adjust accordingly.

This AC-DC converter is designed to maintain a stable output voltage, with a peak current of up to 4.3A. The device also features overload protection, short circuit protection, over-temperature protection and over-voltage protection to prevent undue damage. The unit features a wide operating temperature range (-10°C to +50°C) and can also be used in dusty or humid environments. Moreover, its small size and light weight of only 130g makes it easy to install and integrate into any application.

The working principle of the QGKF-240-24 is based on its switching power converter design. The device is equipped with a toroidal transformer, which serves as a primary control element for the system. The transformer steps down the input voltage into a secondary control voltage that is adjusted using the SCR (silicon-controlled rectifier) circuitry. This control voltage drives the power MOSFET (field-effect transistor) that provides the primary output voltage. The current is then limited and regulated by an LM78LXX voltage regulator IC.

The QGKF-240-24 is a highly efficient AC-DC converter that can be used for a wide range of applications. Its robust design ensures a safe and reliable power supply, with built-in protections for all the major parameters. The device is designed to meet EMC standards, making it suitable for a variety of industrial applications. The unit also features a wide operating temperature range and can be used in dusty or humid environments.
