Inrush Current Limiters (ICL) are a common type of electronic component used to control inrush currents in power supplies, motors, and other similar components. Among them, CL-60 is a commonly used type of inrush current limiter. This article introduces its application field and working principle in detail.

Application Field of CL-60

The application range of CL-60 is very wide, covering nearly all kinds of AC/DC electrical equipments. This kind of inrush current limiter is mainly used in intermediate frequency inverters, motor drives, AC power sources, soft start power supplies, air conditioners, industrial power supplies, home appliances such as refrigerators, and uninterruptible power supplies, etc. In those applications, CL-60 can effectively reduce the current and protect these devices from damage.

Working Principle of CL-60

In terms of its working principle, CL-60 uses a special type of semiconductor circuit to sense the original inrush current. By controlling the conduction of the semiconductor, it can automatically reduce the inrush current to the limited value set by the user. During this process, the CL-60 will use three protection mechanisms – protection against overvoltage, overcurrent and overheating – to ensure that the device operates stably and in a safe manner.

To better illustrate how it works precisely, let us take an example. When the circuit is just powered on, a very high inrush current occurs and will reach a peak value. At this moment, the electrons in the semiconductor turn on and start to control the current to its set value, usually a few amperes. The inrush current, now under control, will go back to the normal working current, thus avoiding overload and damage to the device.

Therefore, CL-60 is a kind of protective circuit and it works as a protector in switching equipments. It can constantly monitor and regulate the circuit to ensure its normal operation.

Conclusion

In conclusion, CL-60 is an inrush current limiter falling into the category of Inrush Current Limiters (ICL). It has wide applications, such as motors, AC/DC power supplies, soft start power supplies, air conditioners, industrial power supplies, home appliances, and uninterruptible power supplies. Its working principle, mainly focusing on sensing and controlling the inrush current, also functions as a protection mechanism to ensure the device’s safety. For this reason, it is adopted in many electronic devices and plays an important role in them.
