TVS (Transient Voltage Suppressors) devices are one of the most important components in power electronic designs. Their function is to limit the transient voltages which can occur in power systems, and by doing so, they protect sensitive circuitry or components from damage or destruction. In particular, MOVs (Metal Oxide Varistors) and ROV10-911K are two of the most common types of TVS devices, and each has its own unique application field and working principle.

MOVs, as the name suggests, rely on a metal-oxide breakdown material in order to operate. This material, which is usually a semiconductor, is normally placed between two electrically conductive plates at a specific voltage. When the AC voltage exceeds this breakdown voltage, the electrical current passes through the material, thus “snubbing” the transient voltage spike. MOVs are mainly used for overvoltage and overcurrent protection in power systems, and can be used for both AC and DC applications.

ROV10-911K is a type of Varistor, which allows a very high-voltage transient to be suppressed quickly and reliably. This is done by arranging a series of zinc oxide discs in a radial configuration, with a number of metallized interfaces. The number of discs and interfaces is determined by the maximum peak transient voltage which needs to be suppressed. The ROV10-911K is mainly used in power systems and telecommunications applications, and can be used to suppress a wide range of transient voltages.

When using ROV10-911K to protect sensitive electronics in power systems, it is important to ensure that the peak transient voltage is within the nominal working range of the Varistor. This is particularly important in high-voltage power systems, where a momentary surge may occur due to capacitive or inductive loading. In addition, the Varistor should be rated for the correct current handling capacity, as an undersized Varistor may not be able to cope with the current demands of the power system.

In summary, MOVs and ROV10-911K devices are two of the most common types of TVS devices, and each has its own unique application field and working principle. It is important to ensure that the Varistor is rated for both the correct peak transient voltage and current handling capacity, in order to protect sensitive electronics in power systems.
