Many kinds of transients have an adverse effect on the performance of the system. Varistors, MOVs, and TVS are all devices that can protect against transients. But all of them function differently. The MOV-20D781KTR is an example of TVS (Transient Voltage Suppressor). Let\'s take a look at its application field and working principle.

Application Field of MOV-20D781KTR

MOV-20D781KTR is a self-correcting surge arrester with a 600W peak power dissipation. It can be used in AC power supply systems, UPS power supply systems, and other power protection systems. Additionally, it is suitable for lighting protection in the circuit and low-voltage power supply circuit.

The TVS MOV-20D781KTR is mainly used for limiting the high-energy pulses generated by lightning, ESD, and EFT. It also can improve the reliability and efficiency of power transmission systems, circuits, etc.

Working Principle of MOV-20D781KTR

The MOV-20D781KTR is a kind of bidirectional protection device. It consists of two components, MOSFETs and diodes. It is connected in parallel across the AC power input and load, and is designed to provide over-voltage and under-voltage protection. When the voltage increases, the MOV-20D781KTRs will start conducting current to protect the power transmission system, and when the voltage decreases, the MOV-20D781KTRs will stop conducting current.

The MOV-20D781KTR also has a low operating voltage of 20V and a peak power dissipation of 600W, which means that it can handle the surge current and protect the circuit very well. However, in order to ensure the safe operation of the system, MOV-20D781KTR should be used with other protective devices.

Conclusion

To sum up, MOV-20D781KTR is a kind of TVS (Transient Voltage Suppressor) that can effectively protect the power supply system from over-voltage, under-voltage, and high-energy pulses. It has a low operating voltage and high peak power dissipation. It can be used in AC power supply systems, UPS power supply systems, and other power protection systems. However, it should be used with other protective devices for safe operation.
