Inrush current limiters (ICLs) are essential components used in a variety of applications ranging from power supplies to motor drives. MS15 30004 is one such type of ICL which restricts the maximum level of inrush current by limiting or suppressing it appropriately. It is widely favoured for its reasonable size, cost-effectiveness and superior performance.

The MS15 30004 ICL is a compact, solid-state, three-terminal device that is used to limit excessive inrush current and protect against over current or over voltage conditions. Its design includes two resistive components: a shunt resistor and a series resistor. The shunt resistor is connected in parallel to the load and the series resistor is connected in series with the load.

When the device is turned on, the inrush current is limited by the impedance of the series resistor and the sum of the both resistances. If the current exceeds the maximum value allowed, the device will reduce it by limiting or suppressing it. In comparison to other types of ICLs, the MS15 30004 limits inrush current more efficiently, as it has a larger resistance, providing better protection against over current or over voltage conditions.

The working principle of the MS15 30004 ICL is relatively simple. When the ICL is turned on, the current is first restricted by the resistance of the series resistor and the shunt resistor. As the current increases beyond the limit, the device reduces or suppresses it to ensure that the maximum current remains within the allowed range. This is carried out without any external components such as Hall-effect transistors.

The MS15 30004 ICL has a wide application range, from low-voltage applications used in consumer electronics and home appliances to high-voltage applications such as wind turbines, medical equipment, and motor drives. It is particularly useful in systems with high inrush current, which could damage other components. By using the ICL, it is possible to reduce the current to a safe level and protect the system from possible damage.

In summary, the MS15 30004 is a cost-effective and good-performing inrush current limiter that is essential in a variety of applications to protect against over current or over voltage conditions. Its design includes two resistive components which together limit inrush current more efficiently than other types of ICLs, making it particularly suitable for systems with high inrush current. The device works based on a simple principle and can be used in low- and high-voltage applications from consumer electronics to motor drives.
