Inrush Current Limiters (ICL) are devices specifically designed to limit surges of current when capacitive and inductive loads are applied or reapplied. In power electronics applications, an ICL is usually placed in circuit between the power source and the load to provide surge protection and promote system efficiency.NF20AA0109MHL is an ICL device developed by NeoPower Inc. It is a single phase inrush current limiter, for use in high reliability applications. Its operating working voltage is 250VAC, with a rated current of 20A, and a maximum surge current capacity of 210A.The main purpose of the NF20AA0109MHL ICL is to provide surge protection and reduce power line transients. Inrush current is the instantaneous increase in current when the load is switched on. This is due to the stored energy in the load capacitor, from the previous cycle, discharging into the circuit. If the inrush current is too high, it can damage the power supply and the load, as well as reducing system efficiency.The NF20AA0109MHL uses a thermal sensing element in its design to allow for better protection from inrush current. The thermal sensing element works by increasing the resistance of the circuit to limit the inrush current. When the load capacitor is charged, the ICL’s resistance is low, allowing for a high surge current and consequently a high inrush current. As the capacitor discharges and the load current decreases, the ICL’s resistance increases, limiting the inrush current.The NF20AA0109MHL ICL is typically used in applications which require controlled and reliable power management. These applications include: high-end servers, power supplies, battery charging, and telecommunications systems. As a result of its efficient performance, the NF20AA0109MHL ICL is also suitable for low power applications such as LED lighting.The NF20AA0109MHL is a reliable, high performance ICL with a durable construction for reliable performance in demanding environments. It has a long rated life with a maximum of 15000 cycles and a guaranteed operational time of at least 3300 hours. The device is also CE, UL, and TUV compliant.In summary, the NF20AA0109MHL is a single phase Inrush Current Limiter designed for use in high reliability applications. Its main purpose is to protect equipment from high inrush currents, which can damage power supplies, loads, and reduce system efficiency. The device works by using a thermal sensing element to increase its resistance when the load capacitor is discharged. The NF20AA0109MHL is suitable for both high power and low power applications, made with a durable construction for long-term reliability and CE, UL, and TUV compliant.
