AC DC Converters are devices that can convert alternating current (AC) to direct current (DC). VSBU-120-30 is one of them, which is designed for DC power distribution systems. This article will introduce the application field and working principle of VSBU-120-30.
Application Field of VSBU-120-30
VSBU-120-30 has a wide range of applications due to its robustness and reliable performance. It is used in various power distribution systems, including power grid inverters, flywheels, energy storage systems, off-grid applications, renewable energy, and more. It is also widely used in commercial and industrial systems, such as solar farms, wind farms, mining, electric vehicles, telecommunications, data centers, railway systems, etc.
Working Principle of VSBU-120-30
VSBU-120-30 is an AC/DC converter which uses a full-bridge rectifier with a low-loss semiconductor switch. This enables it to convert AC power into a DC output voltage that can be precisely regulated and adjusted. The AC source power is divided between two diodes connected in parallel. These diodes create two distinct blocks of output voltage, and the required DC output voltage is determined by the ratio of the two diodes.
The VSBU-120-30 has a control circuit that contains a voltage sensing transformer, a power module, and a controller. The voltage sensing transformer senses the AC voltage and sends a signal to the controller. The controller then sends a signal to the power module which, in turn, regulates the current flow from the AC source. This allows the device to provide a stable output voltage.
The VSBU-120-30 also features advanced protection functions, such as over-current, over-voltage, and over-temperature protection. This protects the AC input from damage due to short circuiting or reverse polarity. Furthermore, it is designed with a feature which limits the stored energy and thereby reduces the energy consumption during normal operation and increases the efficiency of the system.
The VSBU-120-30 is a highly reliable device with its rugged design and superior performance. It is ideal for many power distribution applications, especially where high efficiency and low losses are desired. Its advanced protection features make it an ideal choice for commercial, industrial, and renewable systems.
