Varistors, MOVs, and surge protectors are components found within electrical systems that are designed to monitor and protect electrical equipment against spikes in current, voltage, and power surges. The ROV10-681K-2 is a Varistor, MOV, and surge protector uniquely designed to provide enhanced protection against highenergy voltage transients.

ROV10-681K-2 Application Field

The ROV10-681K-2 is designed to provide UPS systems, telecom systems, industrial control systems, and IT equipment with excellent protection against electrical disturbances in industrial and commercial settings. The Varistor/MOV combination has an operational voltage of up to 120V AC. The surge protector circuit can support current up to a maximum of 300A.

The combination of Varistor and MOVs provide a reliable surge protection device that can survive multiple high-energy voltage transient events. The component provides 8.5mm of clearance through the mounting hole pattern. This makes it ideal for tight installation requirements. The component is also designed to be housed within an IP20 rated enclosure, ensuring better security and protection against environmental factors such as dust and rain.

ROV10-681K-2 Working Principle

The ROV10-681K-2 is made up of two main parts; a Varistor component and an MOV component. The Varistor is responsible for regulating the voltage in the system. It does this by clamping the voltage and allowing it to dissipate as heat. This usually happens when the voltage exceeds the rated voltage of the Varistor.

The MOV component is responsible for providing over-voltage protection for the system. It does this by monitoring the voltage and current levels and limiting them within the safe operational range. The MOV has two modes of operation, active and passive. When in active mode, it is responsible for controlling the system voltage by limiting the current in the system. The MOV will then switch to the passive mode when the voltage and the current in the system reach beyond the set maximum levels.

The combination of Varistors and MOVs provides enhanced circuit protection against multiple high energy transients. The Varistor is designed to protect the system from over-voltage conditions while the MOV provides protection from over-current conditions. Together, they effectively protect the system from a wide variety of electrical disturbances.

Conclusion

The ROV10-681K-2 is a Varistor, MOV, and surge protection that provides superior protection against spikes in current, voltage, and power surges. It is designed to provide UPS systems, telecom systems, industrial control systems, and IT equipment with reliable protection against electrical disturbances. The combination of Varistor and MOV components are designed to withstand multiple high-energy voltage transient events.
