Inrush current limiters (ICLs) refer to flow switch elements that limit the sudden high inrush current that flows through an electric circuit when a power supply is first connected or turned on. The SL18 47003-A current limiter is a type of ICL that has a wide range of applications and a reliable working principle.

The SL18 47003-A current limiter can be used in any power supply requiring inrush current limitation, such as AC/DC power supplies, DC-DC converters, lighting, audio amplifiers and medical equipment. It works by limiting the amount of current that can flow through the circuit by controlling the resistance in the circuit and ensures that any surge in the current is brought safely down to prevent damage to the connected devices.

The SL18 47003-A current limiter is made of high-quality components which make it capable of high performance in most applications. It has a wide range of features, including a current limiting function, high energy transfer and low residual voltage. It also has a low loss of power factor, meaning it can efficiently provide a steady current to the power supply. Additionally, the current limiter has a high switching speed which reduces the time taken for the current to be limited when power is first connected or turned on.

The working principle of the SL18 47003-A current limiter is based on Ohm’s Law. It limits the current passing through the circuit by creating resistance in the circuit. This resistance is caused by the action of the current limiting element, which is a specially designed thermistor. When the current passes through the thermistor, it heats up and its electrical resistivity increases. This increase in resistivity reduces the current in the circuit and prevents the inrush current from causing any damage.

The SL18 47003-A current limiter is a reliable and safe solution for any application that needs inrush current limitation. It has a fast response time, enabling it to limit the inrush current very quickly. Its high-quality, low-loss components make it highly efficient and durable with a long service life. The current limiter provides a secure and efficient way of reducing the sudden, high inrush current and protecting the connected devices.
