TVS - Varistors, MOVs are broadly utilized in the industrial environment, and VC060303A100DP is one of their application fields. It is designed to cover a wide range of industrial power application fields, which includes welding equipment, UPS, communication equipment and power supply systems.

The working principle of VC060303A100DP is based on the characteristics of Metal Oxide Varistors (MOVs). MOVs are devices that can limit surge or transient voltages, resulting from lightning strikes or other fault conditions, and protect the other components in the system.

When relatively high pulse signals reach the MOV, the conductivity of the oxide layer increases significantly. The actual process is the presence of strong non-linearity that is caused in the oxide layer. This rapid increase in conductivity allows almost all of the surge voltage to pass through the MOV and thereby protect the components that are connected downstream from over-voltage damage.

When voltage levels increase, the internal resistance of the MOV also increases. This, together with the capacitance of the MOV, causes a relatively slow time constant as the MOV attenuates signals that decrease in amplitude over time. This time constant is also known as the dynamic resistance of the MOV.

In summary, the VC060303A100DP MOV is designed to protect against short intervals of over voltage. It is able to detect faults in power circuits, reduce pressure peaks generated by lightning discharges, and provide a reliable protection against short circuit and over voltage.
