LS150-48

AC DC Converters

The LS150-48 is an AC to DC converter used to control the full-wave rectification and bridge type frequency conversion for AC current output. It is available in transformer-less designs and can be used to power, regulate and monitor the process of regulated AC current input into DC current. This article will discuss the application field and working principle of the LS150-48.

Application Field

The LS150-48 is used primarily in two fields: 1) In medium-voltage applications such as datacenter applications requiring high quality electrical power and 2) In industrial automation where a reliable and accurate AC to DC converter is needed to control and monitor processes.

In medium-voltage applications, the LS150-48 is used to convert regulated AC current to the DC equivalent, providing power to electrical devices where precision and accuracy in performance is important for the continuity of operations. The LS150-48 is also preferred in this application as it can withstand voltage surge resulting from uncontrolled power grid switches, as well as maintain the desired voltage and current levels when no AC utility source is available.

In industrial automation, the LS150-48 can monitor process condition data, including current and temperature, enabling accurate and stable manufacturing processes for the operator. It is also used to control and regulate AC current and DC current for steady and reliable operations in motors, relays and other electrical switching equipment.

Working principle

The LS150-48 consists of a bridge type frequency conversion circuit where AC voltage is converted into DC voltage, and SMPS (Switch Mode Power Supply) which is used to control the input current and output voltage. The AC voltage is first converted into a lower voltage and frequency AC voltage wave which is then rectified into pulsating direct current. The current will be then smoothed into a DC current for powering a load.

The SMPS is then used to control the input current and output voltage by incorporating feedback loop. This feedback loop is responsible for regulating the output temperature, voltage and current to maintain stable and accurate performance, while minimizing the harmonic distortion.

Conclusion

The LS150-48 is a versatile AC to DC converter used in medium-voltage applications and industrial automation. It is capable of converting regulated AC current into DC current and can also be used to control and regulate the voltage and current for powering a load. By incorporating the feedback loop, the LS150-48 can ensure stable and accurate performance while minimizing harmonic distortion.
