DC DC Converters

DC DC converters are widely used, especially in the modern digital age where multiple power sources are needed to power various electrical and electronic systems. The QHS25ZG-NT DC-DC converter is an example of such a device, and it is used as a voltage stepping and polarity conversion solution for various applications. In this article, we’ll look at the application fields of the QHS25ZG-NT and how it works.

Application Fields

The QHS25ZG-NT DC-DC converter is a 4-pin device designed for use in various industrial and general purpose applications. The high efficiency, dual/triple output bipolar converter is suitable for use in automated processes, medical equipment, building security automation, lighting and instrumentation. It can also be used in applications where the output polarity needs to be switched in order to power certain electronics that require a specific polarity.

Working Principle

The QHS25ZG-NT converter works by taking in a single input voltage, usually between 8 to 18V DC, and then providing two or three regulated output voltages with a total output power of up to 25 watts. The device features a switching frequency of 120kHz to achieve high efficiency conversion of the incoming voltage. The device is switching type, meaning that it features a switching circuit as its main component to convert the input voltage into higher or lower voltages.

The device also features a built-in auto-reset function that allows it to automatically turn off if an overcurrent or overvoltage condition is encountered. A channel control system is also included, which allows the user to configure the output voltage for each output channel. This feature can be used to adjust the voltage output for each channel separately to match the power requirements of the load while also reducing the risk of malfunction.

Conclusion

The QHS25ZG-NT is a versatile and efficient 4-pin DC-DC converter that provides dual/triple output voltages with a total output power of up to 25 watts. It is suitable for use in industrial and general purpose applications where the output voltage needs to be adjusted for different loads. The device also features a built-in auto-reset and channel control system to improve safety and provide additional functionality.
