Current Limiters

Current Limiters

Current limiters are devices that are designed to restrict the flow of electrical current in a circuit to a predetermined level. They are commonly used in a variety of electrical systems to protect sensitive components from damage due to excessive current flow. Current limiters work by sensing the amount of current flowing through a circuit and then reducing the current flow to a safe level if it exceeds a certain threshold. There are several types of current limiters available, including passive and active limiters. Passive limiters are simple devices that use resistors or fuses to limit current flow. Active limiters, on the other hand, use electronic components such as transistors or diodes to actively regulate current flow. Current limiters are used in a variety of applications, including power supplies, motor control circuits, and electronic equipment. They are particularly important in high-voltage systems, where excessive current flow can cause damage to sensitive components or even pose a safety hazard to operators. In addition to protecting electrical components, current limiters can also be used to improve the efficiency of electrical systems. By limiting the amount of current flowing through a circuit, energy consumption can be reduced, which can result in significant cost savings over time. Overall, current limiters are an essential component of many electrical systems, providing protection and efficiency benefits that are critical to the safe and reliable operation of these systems.
