DC-DC converters are electronic circuits used to convert a direct current (DC) from one voltage level to another. One of the most common types of these converters is the REC7.5-123.3SRW/H3/A/M, which is designed primarily for use in industrial applications. This article will discuss the application field and working principle of the aforementioned converter.

The REC7.5-123.3SRW/H3/A/M is a three-phase rectifier designed for use with three-phase AC input power. It has an efficient and compact design, making it ideal for small spaces. It features a special rectifying technology and low-noise operation. This makes it suitable for industrial applications where high quality and reliability are key considerations.

In terms of its application field, the REC7.5-123.3SRW/H3/A/M is suitable for applications such as servo motor control circuits, fiber optic communication systems, automatic voltage controllers, and regulated DC power supplies. It is particularly suitable for applications requiring long-term reliable operation. Furthermore, it is designed to withstand extended periods of power outages and can also support high surge currents, making it ideal for applications with fluctuating loads.

The working principle behind the REC7.5-123.3SRW/H3/A/M is quite simple. The AC input voltage is rectified and therefore converted into a DC output voltage. Once this has been accomplished, it can be filtered to achieve the desired output voltage. In order to ensure the reliability and longevity of the converter components, there are several protective circuits included in the system to guard against accidental over-currents or other faults.

At the heart of the REC7.5-123.3SRW/H3/A/M is a rectifier bridge which is responsible for rectifying the AC input voltage. The bridge is divided into four sections: an upper rectifier bridge, a lower rectifier bridge, a filter branch, and a power section. In order to prevent the power supply from overloading or shutting down, each section is protected by its own protective circuit. This helps to ensure high efficiency and reliability of the converter.

An important feature of the REC7.5-123.3SRW/H3/A/M is its ability to adjust the output voltage according to the load requirements. This is achieved by controlling the current through an auxiliary winding of the rectifier bridge. In addition, the converter can adjust the output voltage by controlling the switching frequency of the rectifier bridge. This helps to reduce the audible and radio frequency interference, making it suitable for use in industrial environments.

In conclusion, the REC7.5-123.3SRW/H3/A/M is a reliable and efficient three-phase rectifier designed for industrial applications. It can be used to convert AC input voltage into DC output voltage, and it also features a voltage adjusting feature which allows it to adjust the output voltage according to the load requirements. Various protective mechanisms have been integrated into the design to ensure it remains safe and reliable even during extended periods of power outages. This converter is therefore ideal for applications requiring reliable and long-term operation.
