Inrush Current Limiters (ICL)

Inrush current limiters offer a specialized protection for electronics equipment against current surges that exceed their design and safe operating parameters. The most common type of inrush current limiter are those designed to be used in conjunction with high-current HVAC units, such as motors, large capacitors, and transformer rectifiers. These types of limiters require careful design consideration to ensure they are adequately rated to protect the device or equipment they are protecting from impact damage due to excessive current.The latest inrush current limiter technology is the MF72-002.5D11, a compact and reliable inrush current limiter manufactured by Murata Power Solutions. It is designed for use in demanding commercial and industrial applications. It features a “C−curve (non-linear) accuracy” which provides better protection than traditional linear-regulation inrush current limiter designs. It also offers exceptional lifetime reliability and is rated for a wide range of amperage levels – from 0.25A to 20A.The MF72-002.5D11 provides precise, predictable inrush-current protection. Its proprietary non-linear response curve allows it to quickly and accurately control the amount of current that flows into a circuit without overloading it or tripping the system, thus protecting the device and equipment. Additionally, it provides protection from inrush-current surges by limiting the amount of current flowing to only what is necessary to properly power up the system without exceeding the device’s rated power or current draw.The MF72-002.5D11 also includes an adjustable reset time delay feature, which can minimize any excess current spikes during the system’s power up cycle or any sudden changes in current draw. This feature helps protect sensitive electronic components from thermal damage due to excess current. Additionally, the limiter features adjustable jump-start control (JSC) that provides even greater protection against excess current and thermal damage. In-circuit testing and evaluation of the MF72-002.5D11’s performance shows that its response time is significantly faster than traditional linear inrush current limiters. The MF72-002.5D11’s response time and current limiting accuracy is optimally tuned to protect the device or system from current surges while ensuring that enough power is available to start up the appliance or system correctly. This makes it an ideal inrush current limiter for a wide range of applications, including HVAC, water, and other high-current machines.The MF72-002.5D11 is also extremely reliable and has a mean-time-between-failure rating of more than 10 million hours, making it a highly durable inrush current limiter that can handle even the harshest environments. It meets UL/CSA 60730-1:2010 safety standards, meaning it is safe to use, and is rated to operate in temperatures ranging from -40 to +125 degrees Celsius. Overall, the MF72-002.5D11 is a reliable and durable inrush current limiter that provides precise, predictable protection against excessive current that could otherwise cause device or system damage. Its non-linear response curve is designed to limit the amount of current that flows into a circuit, while its adjustable reset time delay and jump-start control features further ensure that thermal damage is minimized. With its wide range of amperage levels and its impressive mean-time-between-failure rating, the MF72–002.5D11 inrush current limiter is clearly an ideal choice for a wide range of commercial and industrial applications.
