PTC resettable fuses, also known as polymeric positive temperature coefficient (PPTC) resettables, are electrical devices that can be used to protect circuits from overcurrent conditions. They are found in a wide range of applications from consumer electronics to industrial machinery, and the AHS200-2 is one of the most popular models on the market. This article will explore the application field and working principle of the AHS200-2.

Application Field of AHS200-2

The AHS200-2 is an ideal choice for overcurrent protection in high current applications such as appliances, power supplies, lighting, air-conditioning units, power tools, and industrial machinery. It is capable of providing high current protection up to 200A, with a maximized reset voltage of 370 volts. Its working voltage is 16 volts to 48 volts, making it suitable for a variety of applications, and it is available in both in-line and SMB footprints. Additionally, the polymeric positive temperature coefficient of the AHS200-2 makes it resistant to high temperature conditions, allowing for reliable and safe operation.

Working Principle of AHS200-2

The working principle of the AHS200-2 is based on the polymeric positive temperature coefficient of its integrated components. This means that as the current increases, the temperature of the components rises, which in turn raises the resistance of the PTC. When the current exceeds a certain level, the resistance rises to a point where the current is stopped, thus protecting the circuit from overcurrent conditions. When the overcurrent is removed, the PTC cools down and returns to its original state, allowing for normal current flow.

The AHS200-2 is designed to provide maximum protection against overcurrent conditions in a wide range of applications. The device is compact and lightweight, making it easy to install and maintain, and its advanced polymeric positive temperature coefficient technology ensures reliable performance and maximum safety. Additionally, the device is self-resetting and can be used in both in-line and SMB footprints, allowing for versatile usage in a variety of applications.

Conclusion

The AHS200-2 is a versatile and effective PTC resettable fuse that is suitable for a wide range of applications. Its advanced polymeric positive temperature coefficient technology makes it an ideal choice for high current protection, while its compact size and easy installation make it an excellent choice for any application. The device is designed to provide maximum protection against overcurrent conditions, and its self-resetting capabilities make it an ideal choice for any application requiring reliable and safe operation.
