FD2L036RD Application Field and Working Principle

FD2L036RD is a low voltage protection switch leader for 3-phase AC power lines. It is widely used in electric vehicle charging piles such as grid-connected battery electric vehicles, solar photovoltaic systems and intelligent home electric energy management systems, etc. In order to better understand the application field of FD2L036RD protection switch and its working principles, the following contents are for reference:

1. Application Field of FD2L036RD Protection Switch

FD2L036RD is a medium and low voltage protection switch for AC power line of 5kV or less. It can provide the best and most advanced battery management and overvoltage, undervoltage protection solutions to ensure the safety and stability of electric vehicles in the process of charging. It is usually used in electric vehicle charging piles such as grid-connected battery electric vehicles, solar photovoltaic systems and intelligent home electric energy management systems. The range of the protection switches is very wide. In the grid-connected battery electric vehicle system, it can be used to limit the maximum single cell voltage, to protect each cell from overcharging, and to balance the cells in the whole battery pack. In the solar photovoltaic system, it can be used to protect the photovoltaic array from overload, which ensures the safety and stability of the power system. In the intelligent home electric energy management system, it can be used to protect the battery and provide power for the home lighting circuit, and it can also be used to monitor the home power consumption and control the lighting system.

2. Working Principle of FD2L036RD Protection Switch

FD2L036RD protection switch adopts the three-core balanced structure. When the power line voltage exceeds the preset value, the protection switch will be immediately activated. The positive and negative lines in the power supply system will be disconnected to protect the electrical equipment.The working principle of FD2L036RD protection switch is based on the balance of the three cores of the power line. When the voltage of one of the power lines exceeds the set value, the balance of the three cores will be broken and the protection switch will be activated. Under normal working conditions, the protection switch is in an open state. When the voltage of one of the power lines exceeds the preset threshold, the protection switch will be closed, and the power supply will be disconnected in time to prevent the electrical equipment from being damaged.

Conclusion

In conclusion, FD2L036RD, a low voltage protection switch leader for 3-phase AC power line, is widely used in electric vehicle charging piles such as grid-connected battery electric vehicles, solar photovoltaic systems and intelligent home electric energy management systems. Its working principle is based on the balance of the three cores of the power line. When the voltage of one of the power lines exceeds the set value, the balance of the three cores will be broken and the protection switch will be activated. Thus, FD2L036RD protection switch plays a significant role in protecting electronic equipment from overcharge and overload.
