Inrush current limiters (ICL) are a type of device used to limit the maximum current value that can pass through an electrical circuit. The MS32 5R020 is one of the most popular and widely-used ICLs on the market today. This article will explain the application field and working principle of the MS32 5R020.

Application Field of the MS32 5R020

The MS32 5R020 is designed for use in various applications that require current limiting. It is particularly well-suited to applications where large currents need to be quickly limited in order to avoid damage to electrical components or circuits. These applications include but are not limited to:

• Power supply inrush current limiting
• Battery charging and discharging current limiting
• Motor and transformer protection
• Lighting protection
• Overcurrent protection in various systems

The MS32 5R020 is also well-suited for use in high-voltage, low-current applications.

Working Principle of the MS32 5R020

The MS32 5R020 works by limiting inrush current so that it does not exceed the specified maximum value. It works by incorporating two independently adjustable current-limiting elements. The first element is a built-in resistor, which limits the initial rise in current by reducing the current\'s voltage across it. The second element is a negative temperature coefficient (NTC) thermistor element, which limits the total current flow by reducing the resistance based on internal temperature increases.

Both of these elements are independently adjustable and can be set to any current limit value needed. The combination of these two elements results in a smooth, linear current-limiting response that is tailored for a range of current values. This makes the MS32 5R020 one of the most reliable and cost-effective ICLs available on the market.

Conclusion

The MS32 5R020 is one of the most popular and widely-used ICLs on the market today. It is designed for use in various applications that require current limiting, such as power supply inrush current limiting, motor and transformer protection, lighting protection, and other overcurrent protection in various systems. The MS32 5R020 works by incorporating two independently adjustable current-limiting elements, which results in a smooth, linear current-limiting response tailor-made for a range of current values. This makes the MS32 5R020 one of the most reliable and cost-effective ICLs available.
