Introduction

HJ2-L-AC48V is a power relay designed for robust and reliable use in industrial and commercial applications. The product has current ratings of over two amps, making it a suitable choice for many applications. This article will look at the application field and working principle of HJ2-L-AC48V power relays.

Application Field

HJ2-L-AC48V power relays can be used in a variety of applications, including automotive, HVAC, motor control, and control of electric pumps and fans. The product is also capable of switching high-power loads with minimal arcing, making it suitable for applications where high-power loads are present. Additionally, it can be used in applications where reliable control of AC voltage and current is required.

The product also features a wide range of electrical protection features. It has surge protection for when higher inrush currents exceed the safe operation range of low-power relays. Additionally, HJ2-L-AC48V power relays can provide overcurrent protection, preventing overcurrent scenarios from damaging sensitive equipment. Similarly, the product has a creepage distance of up to 6mm for improved isolation.

Working Principle

HJ2-L-AC48V power relays operate based on an electromagnetic coil. When energised, the coil creates a magnetic field which attracts an armature. The armature then pulls the contacts of the relay closed, completing the electrical circuit. When the relay is de-energised, the armature is released and the contacts return to their open state.

The product has a variety of control options, including both AC and DC current control. It also offers a range of switching functions, including single-pole single-throw (SPST), single-pole double-throw (SPDT) and double-pole double-throw (DPDT). This makes it suitable for a wide range of applications where the control and switching of current are required.

Conclusion

HJ2-L-AC48V power relays are a robust and reliable solution for applications which require high-power switching of DC and AC current. The product has a wide range of electrical protective features and a range of switch functions, making it suitable for a variety of applications. The product operates on a simple electromagnetic principle, with the armature opening and closing the relay contacts in response to changes in the current.
