It is also used in the automotive sector, for control of vehicle power systems, engine control, and emission control systems.

Working Principle

The MJN2CF-AC240 power relay operates using a thermistor controlled fixed frequency switching circuit. This means that it is capable of switching currents 2-3 times faster than conventional relays. The thermistor is used to regulate the power switching frequency -it reacts to changes in the environment, such as increased temperature or current. The thermistor then signals the power switching device to either increase or decrease the power frequency as needed.

The power switching device is triggered by an electric pulse that is generated by a circuit inside of the relay. This pulse travels through the coil of the power switching device, which increases the magnetic field and causes the core to move. This movement of the core activates the contact points, which create a closed power circuit and providing the power needed to trigger the desired action.

The MJN2CF-AC240 power relay has built in overload protection and an AC power switch, which helps to ensure maximum safety and consistency. Both of these safety features work together to quickly detect any over-current or over-voltage situations and disconnect the power accordingly.

Conclusion

Overall, the MJN2CF-AC240 power relay offers a safe, reliable and efficient solution to controlling high-load applications. Its thermistor controlled fixed frequency switching circuit ensures maximum consistency and its built-in safety features protect systems from damage caused by over-current or over-voltage conditions. Additionally, this power relay is UL, CSA, and VDE certified, making it ideal for use in a variety of applications.
