UE43-3MF2D3

A power relay is a key element in the operation of motor-driven industrial applications and other heavy-duty electrical systems. These devices control the flow of electricity and, by default, the operation of the machinery or system they are connected to. The UE43-3MF2D3 power relay is a good example of a device specifically designed to help manage the flow of power.

The UE43-3MF2D3 Specifications

The UE43-3MF2D3 has a number of features which make it unique in its ability to manage the flow of power. It has a rated voltage of 250V DC, short circuit current of 10 A, contact resistance of 20m ohm, contact capacity of 10A resistive, and a dimension of 41×35.8×39.7mm. In addition, the device has a surge current rating of 11A, thermal protection of 65℃, and an insulation resistance of 500M ohm.

The UE43-3MF2D3 Application Field and Working Principle

The UE43-3MF2D3 is specifically designed for applications such as motor-driven industrial devices, apparatuses, and other heavy-duty electrical systems. It is most commonly used in applications requiring high voltage control with a low AC or DC resistance current flow. The UE43-3MF2D3 functions by combining the electromechanical properties of two switches—the reed switch and the contact switch. A reed switch is created when a metal reed is placed between two magnets. This causes the reed to form an electric circuit which is then connected to an external DC power source. The contact switch, meanwhile, is a low voltage device that is operated by an external force.

When the reed switch is turned on, electricity is supplied from the external DC power source to the load. Similarly, when the contact switch is turned on, the load is operated. When the reed switch is opened, the contact switch is opened and the load is disconnected from the power source. In this way, the UE43-3MF2D3 power relay prevents a sudden surge of current from reaching the load as it is kept in a constantly closed state. This also allows for more precise control of the current flow, as it can be easily turned off and on whenever required.

Conclusion

The UE43-3MF2D3 is a powerful and reliable power relay specifically designed to meet the requirements of motor-driven industrial applications and other heavy-duty electrical systems. It is known for its excellent protection against sudden surges of current and its ability to precisely control current flow. This makes it a valuable asset in the realm of power relays, and one that is sure to continue to be used for many years to come.
