JWS480P48

AC/DC converters are electrical devices that convert Alternating Current (AC) to Direct Current (DC). The JWS480P48 is an AC/DC converter that provides an output voltage of 48V and a maximum output current of 480W. It is designed to be used in multiple applications, including automotive, communications, industrial, power supplies, and consumer electronics.

Working Principle

The JWS480P48 utilizes a power conversion circuit that is optimized for low power and high efficiency. This in combination with active current sharing enablesthe JWS480P48 to deliver up to 480W of power. The device has over voltage,over current, over temperature, under voltage, and short circuit protection that preventthe converter from damage due to adverse external conditions.

The device consists of a two-stage power conversion circuit, with the first stagebeing a PFC boost converter. This circuit is used to boost the input voltage from the input source, usually an AC mains, to an intermediate high DC voltage. This voltage is then fed to the second stage, which is a two-phased synchronousbuck converter. This circuit converts the DC voltage into a 48V output.

The JWS480P48 is designed for high efficiency over a wide range of power input,load current, ambient temperature, and conversion frequency. This allows the device to achieve higher levels of power conversion, which in turn reduces power losses and thermal stress on the power components.

The JWS480P48 is used to convert AC to DC in a variety of applications. These include:

• Industrial Machines
• Automotive Chargers
• High Powered LED Lights
• Computer Peripherals
• Small Appliances
• Telecommunication Systems
• Power Supplies
• Solar Panels
• Home Entertainment Systems

The JWS480P48 has a wide operating temperature range of -40°C to 85°C, making it suitable for high power applications that require extreme temperatures. The device also has excellent EMC performance, with less than 5 % total harmonic distortion (THD) and low EMI noise emission.

Conclusion

The JWS480P48 is an efficient AC/DC converter that is designed for use in a variety of applications. It is capable of delivering up to 480W of output power, with excellent efficiency and EMC performance. The device also has built-in protection features that ensure that the converter does not suffer from damage due to external conditions.
