AC DC Converters – DNR30US48-S Application Field and Working Principle

Modern technology continues to require electrical energy converters to effectively turn alternating current (AC) voltage to direct current (DC) voltage or to control the voltage outputs from AC voltage sources. AC DC converters are used across a wide range of industries and applications, from power transmission to testing and research. One of the more recent developments in AC DC conversion is the DNR30US48-S, a single, high-performance power supply and controlled voltage source. The DNR30US48-S is designed primarily for research and prototyping, although it has some applications in light industry.

1. DNR30US48-S Overview

The DNR30US48-S is an AC DC converter from Enviro Tech Inc. It is a single-input, multi-output power supply that produces voltage outputs ranging from 0 to 30VDC, with a maximum output current rating of 0.1A. It operates on either 120VAC or 230VAC electricity, and features adjustable output voltage and current limits. It is also equipped with a digital display that provides an output voltage readout, a control knob for output voltage adjustment, and an adjustable current limit.The dimensions of the DNR30US48-S are 6.7in x 2.4in x 3.1in (17.1cm x 6.2cm x 7.9cm). The power supply weighs approximately 1.6lbs (0.72kg). The device is designed to be energy-efficient and compliant with RoHS standards.

2. Applications

Since it is designed for research and prototype applications, the DNR30US48-S is used primarily by research and development labels, CNC machines, and electronic test and measurement equipment. It can also be used in light industrial settings, such as for small-scale automated equipment, as well as in light commercial settings for industrial control.

3. Working Principle

The primary purpose of the DNR30US48-S is to convert the AC power source into a DC source. This process is known as AC-to-DC conversion, and is the basis for many modern electrical systems. The AC voltage input is first converted to a DC voltage. This DC voltage is then regulated by varying the output voltage and current limits accordingly.The regulation process is accomplished with a feedback loop. The feedback loop consists of an output voltage sensor that detects the voltage from the DC source. A signal related to this output voltage is sent to a differential amplifier. The differential amplifier then adjusts the output voltage based on the information provided by the signal. Finally, the output voltage is adjusted accordingly, ensuring that the final voltage output is as close as possible to the desired value.

4. Conclusion

The DNR30US48-S is a high-performance AC DC converter from EnviroTech Inc. Primarily designed for research and development applications, the converter offers adjustable output voltage and current limits, as well as an LCD display that provides a voltage readout. The device can be used for both research and light industrial settings, although it is not suitable for high power applications. The working principle of the device is based on a feedback loop and AC-to-DC conversion.
