VWRAS2-D48-D5-SIP

DC-DC converters are a type of electronic power supply device used to convert DC power from one voltage level to another. The VWRAS2-D48-D5-SIP is a type of DC-DC converter that is well suited for a wide range of applications. This article will discuss its application field and working principle.

Application Field

The VWRAS2-D48-D5-SIP is a high-efficiency intermediate bus DC-DC converter capable of providing up to 180W of output power with efficiency ratings up to 95%. It is available as both an open-frame and a fully-enclosed variant, featuring input configuration of 24V to 48V and adjustable output voltage from 0V to 48V adjustable in 1V steps. This makes it an ideal solution in a variety of low and medium-power applications, such as automotive, telecommunication, computer servers, data storage, and industrial equipment.

Working Principle

The VWRAS2-D48-D5-SIP DC-DC converter works on the principle of synchronous rectification. This is a process whereby current passes through two switches in order to convert AC power to DC power. In this case, the switches are created from two pairs of opposite-charge MOSFETs (metal oxide field effect transistors). When the positive and negative input are connected to the MOSFET’s control circuitry, complementary signals are generated that, when combined, produce a voltage wave form that causes the MOSFETs to open and close in a manner that rectifies the incoming AC power into DC.

The rectified DC voltage is then fed to the output through two high-speed power stages, which are made up of an inductor and two MOSFETs. The DC output voltage is generated by controlling the switching time of each power stage and regulating the current flow through the inductor. This alternating current-to-direct current process is known as buck-boost conversion, allowing the output voltage to be adjusted from 0V to 48V with a minimum of wasted energy.

The VWRAS2-D48-D5-SIP DC-DC converter is also equipped with a wide variety of protection features including over-voltage, over-current, and over-temperature. This provides an extra layer of protection and helps to ensure reliable operation in most applications. Additionally, the converter is also compliant with the latest IEC60950-1 safety requirements, which ensures even higher levels of protection for any equipment it is used with.

Conclusion

The VWRAS2-D48-D5-SIP is an efficient and reliable DC-DC converter suitable for low and medium-power applications. Its features, such as adjustable output voltage and multiple safety protection capabilities, make it a great choice for a variety of applications. Furthermore, its compliance with IEC60950-1 further reinforces its reliability and trustworthiness.
