SDS60UQ03

AC/DC converters find countless uses in modern industry, from power supplies and motor control to industrial automation. The SDS60UQ03 converter is one such product, developed by Schneider Electric for AC/DC applications where reliability, efficiency, and longevity are key considerations. In this article, we will discuss the application field and working principle of SDS60UQ03.

Design and Construction

The SDS60UQ03 is a 18.5 KVA single-phase three-phase AC/DC power converter featuring a three-phase input and a single-phase output. The unit is designed to be highly efficient and reliable, with a power density of 131 W/in³. It is enclosed in a shock-resistant aluminum housing and includes a heatsink, fan, and protective device.

The converter utilizes a series-regulator converter topology, with a single-bridge rectifier between the input and output stages. The single bridge rectifier provides a bidirectional conversion of AC to DC, making it an excellent choice for applications requiring a DC output. In addition, the converter uses active PFC (power factor correction ) for enhanced efficiency and consistent power delivery. It also features over- and under-voltage protection and over-current protection.

Applications

The SDS60UQ03 is an excellent choice for applications that require efficient and reliable power conversion such as heating and cooling, industrial automation, motor control, and lighting. Additionally, it is suitable for applications where a low-voltage DC output is needed such as solar power systems. The converter’s over-voltage and over-current protection also make it suitable for use in hazardous and hostile environments.

Working Principle

The SDS60UQ03 converter works by converting AC power from an input source to DC power. The single-bridge rectifier between the input and output stages converts the AC power to a DC voltage, which is then regulated by the active PFC circuit. The regulated DC voltage is then supplied to the output stages, where it is then either directly converted or further regulated for a desired output voltage.

In addition to the conversion process, the converter’s active PFC circuit ensures that the input source is supplied with consistent power, which reduces stress on the power system and increases the efficiency of the converter. Additionally, the over- and under-voltage protection help protect the converter from environmental and environmental changes. Lastly, the over-current protection helps prevent the converter from experiencing damage due to overload.

Conclusion

The SDS60UQ03 converter is a reliable and efficient AC/DC power converter that can be used in a variety of applications. Its series-regulator topology, active PFC, and protection features make it suitable for hazardous and hostile environments. Additionally, its efficiency and reliability make it an excellent choice for solar power systems, industrial automation, and motor control.
