Inrush Current Limiters (ICLs) play a crucial role in controlling the current flow in electrical circuits and ensuring that the system is functioning reliably. This technology is used in many industries, including industrial automation, telecommunications, and power engineering. As such, engineers must be aware of the different components and how they work. The AS32 1R030 is an example of one such ICL, and its application fields and working principle will be discussed in this article.
The AS32 1R030 is a three-terminal thermistor inrush current limiter used to reduce the inrush current when electrical systems are turned on. It operates with a maximum operating temperature of 80°C and has a maximin power dissipation of 1.9 W. The device is composed of a thermistor and a bypass resistance network, and it is normally used in AC/DC switching power supplies and DC/DC converters.
In terms of its working principle, the AS32 1R030 operates as inrush current limiter by utilizing the negative temperature coefficient feature of the thermistor. When the device is first activated or when a large system load is connected to the power, a current surge flows through the thermistor, which heats up the device and causes the thermistor’s resistive value to decrease. This creates a voltage drop across the thermistor which then reduces the current flow and limits the inrush current.
The AS32 1R030 has a wide range of applications in different industries. It is used in AC/DC switching power supplies to limit inrush current. It is also used in DC/DC converters to regulate the input voltage and prolong the life of the device. Additionally, it can be used to protect power fail circuitry or to improve power supply behaviour in circuits with long cable runs. Finally, the AS32 1R030 can be used to protect large motors and other electrical devices from over-current conditions.
In conclusion, the AS32 1R030 is a three-terminal thermistor inrush current limiter used to reduce the inrush current when electrical systems are turned on. The device works by utilizing the negative temperature coefficient of the thermistor, and it is typically used in AC/DC switching power supplies and DC/DC converters. Additionally, it also has various applications in other industries, such as power fail circuitry and the protection of large motors and other electrical devices.
