Power relays are a common form of control in many power control systems. Among them, HJ2-T-AC48V is one of the popular ones. It is a special form of contactor, which is used in a variety of applications. In this article, we will discuss the application fields and working principle of HJ2-T-AC48V.

Application Field of HJ2-T-AC48V

HJ2-T-AC48V has wide application fields, mainly used in AC loads with rated value and higher than 2 Amps. For example, it can be used to control AC motors, transistors, transformers, inductors, condensers, etc. It is also widely used in electric welding, aviation and aerospace, rail transit, automotive industry, military industry, etc. In all of these application fields, HJ2-T-AC48V can perform its work efficiently and reliably.

Working Principle of HJ2-T-AC48V

HJ2-T-AC48V is a voltage-controlled, contactor-type power relay with three independent contactors, which control the current flows in the circuit. The relay is operated by changing the voltage applied to its coil. When the voltage applied to the coil is high, the contactors close, and when the voltage applied to the coil is low, the contactors open. The contactors can be used to control the current to the load.

Above the coil is an arc suppression device, which helps to reduce the risk of electric arcs from occurring when the contactors open or close. There is also a magnetic switch, which is used to further reduce the chances of circuit instability. Finally, the relay also features an overload protection device, which prevents overcurrents from flowing through the coil and causing damage to the relay.

Conclusion

In conclusion, HJ2-T-AC48V is a versatile power relay with a wide array of application fields and a well-defined working principle. It is mainly used to control AC loads with a rated value higher than 2 Amps, such as AC motors, transistors, transformers, inductors, condensers, etc. Moreover, it also features an arc suppression device, a magnetic switch, and an overload protection device, which ensure that the relay is stable and reliable in operation.
