DC-DC Converters play an important role in making our electrical systems more reliable. They are used to convert a direct current (DC) into a regulated voltage used by other components within the system. Advanced DC-DC converters, such as the GQ2540-9R, also act as an electrically isolator, providing a safety barrier between the components for both personnel and equipment. Here we will take a closer look at the GQ2540-9R application field and working principle.

Application Field

The GQ2540-9R is a compact, high efficiency, 12V isolated DC/DC converter. The product utilizes an advanced oscillator made from high frequency, low EMI parts which is able to reduce noise to the lowest levels and provide maximum efficiency. The GQ2540-9R is optimal for use in the following application fields:

• Automotive and Industrial Systems.
• Data Communication.
• Telecommunication.
• Medical Devices.
• Surveillance and Security.

Working Principle

The GQ2540-9R uses an innovative approach to provide the best performance from its input voltage. It has a DC-DC boost converter that converts 12V DC to 24V DC with very high efficiency. In order to do this, a PWM (pulse width modulation) square wave is used to control the voltage/current waveform to the load. The PWM switch is ON for a certain amount of time then OFF for the other amount of time. This is called “pulse width modulation” and can be programmed according to the application for optimum performance.

The GQ2540-9R also has a unique “soft start” feature that helps reduce inrush currents, thus reducing noise and eliminating damage to the load. This “soft start” feature provides a gradual increase of output voltage over a short period of time. In addition, this DC/DC converter provides a wide range of output voltage adjustment from 10.5V to 26.5V.

The GQ2540-9R is designed for use in automotive as well as harsh industrial applications. With a wide input voltage range of 8125V at full load and a wide working temperature range from -40°C to +85°C (non-condensing), it is suitable for a variety of applications. It also has a thermal shutdown circuit that will protect the unit from damage due to overtemperature.

Conclusion

The GQ2540-9R DC-DC converter offers a great solution to the needs of various applications. Its unique design of the oscillator, advanced soft start features and wide input range make it an ideal choice for use in a variety of industrial and automotive applications. It’s compact, efficient and reliable, and provides a safe and reliable power supply for your projects.
