Inrush Current Limiters (ICL) are active components used in power supply circuits to limit inrush currents when applied power is first applied, ensuring quick protection for sensitive components. The B57364S2259A2 is specifically designed for use in equipment with rated voltages below 250V AC/DC. The B57364S2259A2 comprises of a thermal element, a triac and a snubber circuit. The thermal element is composed of a nichrom-wire heater which, when current is applied, behaves like an inrush current limiter. When activated, the thermal element operates to absorb the energy of the inrush current. This limits current variance, thus protecting sensitive components downstream of the limiter. Alongside the thermal element, the B57364S2259A2 has a triac which acts as a current monitoring device. This device is responsible for triggering and turning off the power supply circuit after a maximum allowable inrush current is detected. The triac also provides additional protection for the device, preventing dangerous short-circuits in the circuit. The last component of the B57364S2259A2 is the snubber circuit, a device which is made from a series of capacitor, diode and resistor components. It acts to reduce the stress on the circuit by absorbing high voltage and high energy transients. This helps to prevent sparking and other anomalies in the circuit that could damage the device. Furthermore, the snubber circuit limits the amount of high frequency noise in the power supply, ensuring that the device operates with minimal noise.The B57364S2259A2 is commonly used in a wide range of applications. These include power supply and battery chargers, LED lighting systems, electronic motor controllers, automotive and industrial power supplies, internet routers, home appliances and more. Specifically, the device is suitable for use in environments where inrush current and maximum current needs to be limited for safety and stability. In conclusion, the B57364S2259A2 is an inrush current limiter designed for use in low voltage AC/DC power systems. The device is designed for robust and reliable protection, and is well suited for a wide range of applications, from automotive to home appliances. The B57364S2259A2 offers reliable, fast protection unprecedented to other inrush current limiters on the market.
