VS-20AWT04HE3

The VS-20AWT04HE3 is a rectifier module designed by Vicor Corporation. It is comprised of a rectifier bridge, a panel heat sink, a terminal block, and a protection circuit. It is designed for use in a variety of electrical and industrial applications, including AC/DC rectification, DC/DC conversion, and AC/DC load switching. Because of its high power density, the VS-20AWT04HE3 can be used in a wide range of applications where space is a critical factor.

The rectifier bridge of the VS-20AWT04HE3 is made up of two double-sided cooled heatsinks, which are connected in series with two double-row terminals blocks, each supporting 4 cells in different configurations. As a result, the bridge is capable of supporting up to 8 cells when operated in the series configuration. It is rated for up to 1000V and 200A, making it ideal for high current applications.

The panel heat sink of the VS-20AWT04HE3 is designed to dissipate a significant amount of heat generated by the module during operation. It is comprised of two double-sided cooled aluminum extrusions, which are connected in series and secured to the module via a mounting bracket. The heat sink is designed to work in tandem with additional cooling methods, such as air- or water-cooling, to ensure the reliable operation of the module.

The terminal block of the VS-20AWT04HE3 is made up of two double-row terminals, each able to support up to 4 cells in series. It is designed to provide easy and secure connections between the bridge and other components and systems. The terminal block is also equipped with multiple test points and diagnostic LEDs for monitoring and troubleshooting.

The protection circuit of the VS-20AWT04HE3 is composed of three main elements: two current limiters, an overvoltage protection, and a thermal protection. The current limiters are designed to provide a safe level of current through the module, while the overvoltage protection ensures that the module does not become damaged in the event of an increase in the input voltage. Finally, the thermal protection ensures that the module does not overheat during operation.

The VS-20AWT04HE3 is a versatile and robust rectifier module that can be used in a variety of application fields. It is suitable for applications such as AC/DC rectification, DC/DC conversion, AC/DC load switching, battery charging, motor control, HVAC systems, and more. Its high power density and built-in protection make it an ideal choice for applications where space is a critical factor.
