STEVAL-ISA047V2

Evaluation boards are a great tool for design engineers to simulate, evaluate, and optimize power supplies. STEVAL-ISA047V2, DC/DC & AC/DC (Off-Line) SMPS, is one such evaluation board that could be used by engineers in various applications. The evaluation board operates using a wide input voltage range, from 85 V to 265 V. It provides reliable protection against overload, short-circuit, over-voltage, and over-temperature.

The power supply of the board consists of two stages: the primary stage, which is used for supplying a fixed 380 VDC, and the secondary stage, which is used for providing adjustable 0V to 400V output voltage. The efficiency of the board is 95% and the output power can be adjusted up to 1000 mA. In order to ensure the quality and safety of the board, it is designed with an isolation voltage of 2500Vdc.

The power supply of the board can be used for applications such as lighting, industrial automation, and renewable energy. The board can be used to evaluate different types of lighting products such as LED, plasma, and fluorescent lamps. It is also suitable for applications with varying levels of power demand such as industrial controllers, sensors, and electric drives. The board can also be used in renewable energy applications such as solar energy, wind energy, and hydropower.

The working principle of the board is very simple and straightforward. The input power is converted into a DC voltage using several power supply components such as the full bridge diode, transformer, and an energy storage capacitor. The voltage is then regulated and fed to an adjustable voltage regulator IC, which provides the output voltage. The output voltage is also protected against overload, short-circuit, over-voltage, and over-temperature through the implementation of different protection devices.

In order to ensure maximum reliability and efficiency, the board comes with several protection features such as over-current protection and temperature limiting. The board also features current limiting and soft start functions, which help in preventing sudden surges in output current. In addition to this, the design of the board is compact and lightweight, which makes it ideal for portable applications.

In summary, STEVAL-ISA047V2 DC/DC & AC/DC (Off-Line) SMPS is an ideal evaluation board for design engineers. It operates with a wide input voltage range, provides reliable protection features, and is highly efficient. The power supply of the board can be used for applications such as lighting, industrial automation, and renewable energy. The board also features several protection features and has a compact and lightweight design, making it ideal for portable applications.
