Inrush Current Limiters (ICLs), or Surge Limiters, are a type of electronic device intended to protect electrical systems chosen from a condition known as inrush current. Inrush current is the sudden wave of current that flows into an electrical system when first turned on or power is surged to it. As the wave of current is experienced, the electrical system suddenly sees a higher than normal load, and it can cause an overload of the system. In order to prevent damage to the system’s component parts, an ICL can be installed to limit the maximum current the system receives.The SL22 20007-B is one type of ICL that is available, and it is specifically designed to prevent inrush current damage to the components of electrical systems that employ high-current systems. The SL22 20007-B can be used in many types of systems, including consumer and industrial systems such as electrical appliances, air conditioners, vending machines, medical equipment, and more.The working principle for the SL22 20007-B is relatively straightforward. When the unit is connected to a system’s power source and power is applied, the ICL circuit immediately begins to limit the current. This limitation is due to the inner circuit’s ability to create an artificial higher impedance in the power line until the current is limited to a safe level. As the current is limited, the ICL’s artificial impedance begins to decrease, allowing the voltage to pass through the power line unaffected.The SL22 20007-B includes components such as a combination of positive and negative thermistors, which work together to limit current. The thermistors act as a pair of resistors, with one thermistor opposing the current’s passage and the other allowing it. At the point of maximum current, the negative thermistor becomes more resistive, causing the current flow to be limited. Once the current passes the rated limit, the thermistor returns to its original state and allow the current flow again.A second component of the SL22 20007-B is an energy storage element that is designed to store energy at the point of maximum current. This is used to keep the power correctly regulated and to protect against any sudden drops in voltage. The energy stored in the element will slowly dissipate as the current stabilizes, creating a stable and reliable circuit.The SL22 20007-B ICL is designed to be both compact and reliable. It is also designed to be able to withstand high temperatures and vibration, making it suitable for use in a variety of applications. Its size makes it easy to install in any system, and the fact that it is able to limit the current without introducing noise or distortion to the power line makes it an ideal solution for many types of electrical systems.Overall, the SL22 20007-B ICL is an efficient and reliable way to protect expensive electrical systems components from inrush current damage. Its components are designed to limit maximum current, store energy at the point of maximum current, and reduce any noise or distortion. This makes it suitable for a wide range of electrical systems, ensuring the safety of electronic equipment for years to come.
