The SL22 2R515-A is a rugged, reliable, and cost-effective solution for controlling inrush current in most applications.

Working Principle

The SL22 2R515-A is designed to limit the amount of inrush current in a circuit. Inrush current is a surge of current that occurs when a power supply is initially turned on. This surge of current can cause damage to components and impose heavy loads on power supplies, causing them to fail prematurely or shut down unexpectedly. The SL22 2R515-A is designed to limit inrush current by providing a circuit with a high impedance, resulting in a reduced inrush current.

The SL22 2R515-A consists of a resistor and a diode wired in series. The resistor provides a high impedance for the circuit, while the diode serves as a short circuit when the voltage across it exceeds a certain threshold. This threshold is easily adjustable and can be set as high as 25V. Once this threshold is exceeded, the diode short-circuits, providing a return path for the inrush current to flow. This limits the inrush current to a safe level, preventing damage to components and allowing the circuit to operate smoothly.

The SL22 2R515-A is a reliable and cost-effective solution for controlling inrush current in a range of commercial, industrial, and consumer applications. The unit is designed for use in motor start circuits, lighting control systems, and other applications that require inrush current limitation. Its wide range of voltage ratings makes it suitable for a wide variety of applications, and its adjustable threshold allows it to be easily tailored to the specific needs of each application. The SL22 2R515-A is a rugged and reliable solution for controlling inrush current in most applications.
