TVS and MOVs (Metal Oxide Varistors) are essentially two-port devices that consist of two statements regarding their electrical behavior. The first statement pertains to their application field and working principle, and the second statement pertains to their operation during short or open-circuit faults. Varistors may be used either to limit the severity of transients on input power lines, stabilizing system voltages, or as a sensing device for protecting against excessive current.

ROV07-681K-S is a varistor device with an exceptional wide range of working voltage. It provides 7 KV (7000 volts) of clamping voltage withstanding capability when the surge waveform is applied. It also offers excellent thermal stability performance, fast response time, and a high current handling capability. ROV07-681K-S is a great choice for applications that require surge protection.

Varistors are used to protect systems against high voltage transients that may occur from lightning or electrical surges. Varistors help to minimize the effects of these sudden voltage fluctuations by providing a given voltage limit which when exceeded, the varistor begins to clamp the voltage, and suppress the surge. The varistor works similarly to a fuse or circuit breaker, in that it also provides a thermal solution, activated at higher current surges, that would further prevent circuit damage.

The ROV07-681K-S varistor works by providing a high resistance path for current changes from a continuous operation to the short-term high voltages. The energy is then diverted to a low resistance path when overvoltages occur. As the intense energy is consumed by the device, the voltage rises sharply, thus limiting the peak voltage to a predetermined level.

The varistor is designed to provide increased protection from damages such as flashover, breakdowns, or electric arcs. The varistor also isolates the sensitive circuits from relay contacts, switches, transformers, etc. which can cause transients. When the ROV07-681K-S varistor is connected in series, this increases the protection offered, since the overvoltage can be clamped by multiple devices.

To ensure proper functioning, it is important to observe the parameters carefully during the design phase. The peak voltages and currents ratings must be considered in order to ensure the type of protection provided. The temperature environment should also be taken into consideration when selecting the varistor.

In conclusion, the ROV07-681K-S varistor, as a part of TVS and MOVs is an effective surge protection solution for a broad range of applications. Varistors are used to limit the severity of transients on input power lines, stabilizing system voltages, or as a sensing device for protecting against excessive current. ROV07-681K-S varistors provide 7 KV (7000 volts) of clamping voltage withstanding capability, fast response time, and a high current handling capability, making them the right device for surge protection applications.
