Inrush Current Limiters (ICL)

Inrush current limiters (ICL) are used to protect electronic equipment against the damaging effects of large inrush currents when they are initially powered up or powered down. In order to maintain safe levels of power delivery, ICLs limit the amount of current allowed to flow through the circuit. Among the different types of ICL, SL15 1R010 is one of the most common and is widely used across a variety of industries.

The Application Field For SL15 1R010

SL15 1R010 ICLs are mainly employed in industrial applications, such as those involving motors, pumps, fans and HVAC systems. More specifically, the common areas that they are used in include the following:• Residential air-conditioning control boards• Industrial HVAC systems• Motor controls• Industrial automation• Pump control systems• Electrical enclosures.

The Working Principle of SL15 1R010

SL15 1R010 Inrush current limiters work on a simple principle. When the power is initially turned on, a large surge of current is generated. This current must be limited to ensure safe operation of the appliance. The SL15 1R010 does this by introducing a resistor in series with the circuit. The resistor allows a reduced current to flow, thus limiting the amount of power that can be drawn from the circuit.The resistor is designed with a thermistor, which acts as a temperature-sensitive switch. When the power is first applied, the thermistor heats up quickly and acts like a closed circuit, allowing the large surge of current to pass through. As it heats up further, the resistance of the thermistor increases, limiting the current. Once the appliance reaches its normal operating temperature, the thermistor cools down and returns to its original state, bypassing the current.

Conclusion

Inrush current limiters (ICLs) are important components in any electronic system, and SL15 1R010 is a popular member of this family. It is used in a variety of industrial applications, and it works by introducing a resistor with a temperature-sensitive switch. This allows a large surge of current to be limited to safe levels of power delivery, thus protecting the system from the potentially damaging effects of high inrush currents.
