TVS - Varistors, MOVs is a term that is widely used for a wide range of electrical surge protection products. ROV07-621K-S is one of these products and is used to protect electrical circuits and systems from voltage surges above normal operating levels. The high-performance, miniature metal oxide varistor (MOV) ROV07-621K-S is designed for industrial and industrial-grade power applications.

MOVs are electronic components that are made of varistor ceramic material with a metal oxide layer on one or both ends that offers active protection against high-voltage electrical surges. MOVs can be used to protect both AC and DC circuits from voltage overcurrent and overvoltage conditions. The MOVs can be combined with other components such as fuses, fusible plugs, and circuit breakers to provide more complete protection for circuits from voltage surges. MOVs have a low-resistance contact path between them and the circuit and provide a high level of reliability.

ROV07-621K-S is a low-capacitance MOV with a breakdown voltage rating of 621kV and a decay energy rating of 1.2J. The MOV also had a maximum surge current rating of 0.1A and a continuous current rating of 0.1A. The MOV has an ultra-low parasitic capacitance of 0.8 pF, which ensures that the voltage drop across the MOV during normal operation will be kept very low.

The primary application fields for ROV07-621K-S MOVs are: industrial motor control, power system, renewables, HVAC, elevator & escalator and its working principle is to protect the circuit from the harm caused by the instantaneous surge in voltage. This is done by using a low-value, high-resistance connection between the MOV and the circuit. In the event of an overvoltage, the MOV will become active and reduce the circuit\'s voltage, providing protection from overvoltage.

ROV07-621K-S can also be used for transient voltage suppression (TVS), which is a technique used to protect delicate electronic components from overvoltage and overcurrent conditions. The MOVs are designed to absorb the transient energy and limit the voltage surge duration, thereby preventing damage to sensitive electronic components from the transient surge. MOVs should be used in combination with a TVS diode to provide the most comprehensive protection from voltage transients.

ROV07-621K-S MOVs can also be used for line suppression. Line suppression is a technique used to prevent power quality issues such as voltage sag, surge, and overvoltage. The MOVs act as a buffer between the power line and the circuit, absorbing the transient energy. This reduces the voltage sags or peaks on the power line, providing protection from voltage surge.

ROV07-621K-S MOVs are also used for lightning protection. MOVs are used in combination with fusible plugs and other components to protect equipment and buildings from direct lightning strikes. The MOVs absorb the transient current from a strike and act as a ground path for the current causing minimal disruption to the equipment.

In summary, ROV07-621K-S MOVs are widely used in industrial and industrial-grade power applications for transient voltage suppression, line suppression, and lightning protection. The MOVs are designed to provide an effective and reliable level of protection from voltage surges and transients. MOVs are widely used in the industry due to their low-resistance contact path and high level of reliability.
