AC DC Converters: DNR18US15 Application Field and Working Principle

The DNR18US15 (1-Phase Digital Network Regulator) is an AC DC converter designed and manufactured by 2D Instruments. It is a high-efficiency, multi-function and compact AC DC converter. This practical and reliable device is used in industrial electronics to convert AC power to DC power.

The main purpose of the use of this device is to transform the input of AC voltage and power into DC voltage and power so that it can be used more widely in in many forms of industrial electronics. The DNR18US15 is used in the fields of medical, communication, machinery and testing, among others.

This device has a simple and robust working principle. In the AC DC converter, the input voltage is provided by the AC power source and the system needs to be rectified. The DNR18US15 uses two rectifying bridges to rectify the input voltage. Once the voltage is rectified, it will be delivered to the output through a dc-dc converter and an output capacitor.

The output is regulated by the feedback network. This feedback network is composed of a reference voltage source, an error amplifier, and a power comparison module, which are connected to the output of the dc-dc converter. Through these components, the feedback network can compare the input voltage of the dc-dc converter and the output voltage of the output capacitor and then send out the control signal of the output voltage regulator accordingly.

Due to its fast response performance, the DNR18US15 can quickly respond to the load fluctuations and maintain the output voltage by adjusting the on-time of the switch. Moreover, the device has an extremely high conversion efficiency (up to 96%) which can reduce power losses and increase the system reliability. In addition, the device has a wide output voltage range, can operate from 30V to 580V, and can be used in a variety of different applications.

In conclusion, the DNR18US15 is a reliable and efficient high-quality AC DC converter. The device can efficiently convert AC power to DC power and has an Eagle on-time control system to maintain stability during operation. In addition, the device has a wide output voltage range and a high conversion efficiency, making it suitable for a variety of different applications.
