HJ4-L-DC48V-D is a power relay with an rated power of over 2 Amps. It is designed to control an AC or DC voltage circuit within a given range and is used to drive an internal or external connected load. The relay’s main function is to switch an electrical circuit on or off when necessary.

Application Field

HJ4-L-DC48V-D has a variety of applications. It can be used to control power switch circuit, effectively preventing overload, short circuit and other electrically hazardous conditions. It is extensively employed in electric welding machines, electrical navigation systems and communications, and home appliance switching and protection. It also has a vast use in air conditioners, refrigerators, water pumps, motor control and lighting systems for industrial and civil buildings. Also, its low coil power consumption, combined with its high voltage-based switching capabilities, make it ideally suitable for the emerging electric power industry.

Working Principle

HJ4-L-DC48V-D is a very simple electromagnetic device. It consists of a coil and a contact. When a suitable voltage is applied to the coil, it produces a magnetic field, which causes the armature to move and open or close the contact. This contact has two states: open or closed. When it is closed, it allows the current to flow from the supply to the load and when it is open, it stops the current, thereby switching the circuit off.

The application voltage range of HJ4-L-DC48V-D power relay is between 48 volts DC volts. Depending on the connected load, the maximum rated current can be up to 13 Amps. Its electromechanical performance is reliable even in the harsh environments, such as high temperature, fluctuating humidity, and strong vibration. Moreover, compact design of the power relay helps to minimize mounting space and reduces the wiring cost.

The contact material of HJ4-L-DC48V-D power relay is Silver Alloy for better performance. The silver alloy contact provides improved sensitivity, higher contact voltage, and further reduced contact resistance. It is highly resistant to wear and tear, providing more than 10,000 electrical and mechanical operations.

HJ4-L-DC48V-D is a cost-efficient and reliable power relay for a wide range of applications.
