Inrush Current Limiters (ICLs) are a breed of electrical component designed to help control the flow of electrical currents from a power supply. This type of device is particularly useful in applications where high power draw and large signal surges are expected.The SL15 22101 is an example of this type of device. It is designed to control the inrush current of both AC and DC sources when faced with sudden power draw spikes. By helping to regulate the flow of current, the device can help protect sensitive electronics downstream from the power source from painful power draw spikes, which can cause severe damage.

The SL15 22101 is a cost-effective off-the-shelf solution for inrush current control. It features a clamp circuit, a resistive element, and two differential transformers. The clamp circuit contains two Diodes placed in series. The clamp circuit effectively limits the rise of the max input current. The incoming current is diverted away from the sensitive device or circuit downstream before it rises to a level that would cause damage. The resistive element helps to provide further damping, making the current spikes smaller. Finally, the two differential transformers help to monitor the current draw and take the appropriate action to limit the inrush current.

The SL15 22101 is particularly relevant for applications such as air-conditioning systems or heating systems that require energy in short bursts or power spikes. While these power draw spikes may be necessary, they can also cause damage to the circuit downstream, which is where the inrush current limiter comes in. By providing a moderate stream of current into the circuit during the start-up period of the application, the limiter hopefully helps to mitigate against any damaging current spikes that may have happened without protection.

The SL15 22101 has a number of other interesting features that make it particularly interesting to designers looking for inrush current control solutions. It has an adjustable inrush and carrying current limit, meaning that the current highest level of current can be set and maintained, potentially allowing for greater protection against power draw spikes. An interesting feature of the device is its thermal protection settings, which help to further limit the current draw if the temperature of the system rises too high, thanks to the integrated thermal sensor.

Overall, the SL15 22101 is a handy component shielding sensitive electrical circuits. Thanks to its clamp-circuit, resistive element, and differential transformers, it helps to ensure that power draw spikes that strike the sensitive device or circuit will not cause any long-term damage. Its adjustable inrush and carrying current limit and thermal protection settings help to provide additional protection against these power draw surges, making it a fantastic choice for applications that may be vulnerable to such occasions.
