Inrush current limiting (ICL) is an important technology in the modern world, aiming at providing outstanding protection against short-term or transient over-currents. The SL15 60002-A is a great example of an ICL, with its application field and working principle described here.

Application Field

The SL15 60002-A is designed to protect semiconductors, toroidal transformers and a wide variety of other electrical and electronic components from destructive inrush currents; furthermore, it also prevents system overloads and helps maintain circuit integrity. This type of protection is critical for applications dealing with high-frequency and high-voltage power electronics.

The SL15 60002-A ICL is available in various configurations, including in-line, panel-mount, and surface-mount, and is rated for operation from -40ºC to +85ºC. These features make it suitable for use in telecommunications, oil & gas instrumentation, electrical power distribution, medical device manufacturing, and other industries that demand reliable and high-precision components. In short, the SL15 60002-A can be deployed in virtually any application where transient over-currents need to be managed or prevented.

Working Principle

The SL15 60002-A works on a simple idea: it limits the maximum inrush current by inserting a short-circuit element between the incoming power source and the connected components. This process occurs in steps, starting with the opening of a control transistor, followed by the closing of an electronic switch. This is essentially a form of switching, where the control transistor and electronic switch are designed to match the conditions of the incoming power supply.

When the inrush current exceeds the specified limit, the control transistor is triggered, and the electronic switch is closed. The ICL then draws the current away from the line, preventing catastrophic power problems from occurring, and protecting the connected components from overloads. The switch is held closed until the current is reduced below the specified limit, at which point it is opened again.

Inrush current limiters are highly reliable and economical solutions for managing transient over-currents. The SL15 60002-A is one of the best ICLs on the market, and can be trusted to provide superior protection for sensitive electrical and electronic components.
