TVS (Transient Voltage Suppressor), MOVs (Metal Oxide Varistors), and ROVs (Rotating Varistor) are all various types of varistors used to protect against overvoltage in electrical systems. ROV05-241K-S-2 is a specific type of ROV (Rotating Varistor). This article will discuss the application field and working principle of ROV05-241K-S-2.

Application Field

ROV05-241K-S-2 is a transient voltage surge suppressor designed to protect against hazardous overvoltage conditions in modern electrical and electronic equipment. It is designed to be used in a variety of domestic, industrial, commercial, transportation, and military applications, and is particularly useful for protecting power supply systems, communication systems, automatic control systems, and electronic equipment.

ROV05-241K-S-2 is designed to clamp high voltage transients to a safe level, allowing the system to continue working without damage or disruption. It is designed to protect equipment from spikes caused by various external sources, such as lightning strikes or switching surges. It is also effective against internally generated surges due to inductive loads such as motors and solenoids.

ROV05-241K-S-2 is optimized for low capability per unit volume, and is highly reliable and cost effective. Its integral structure is compact, and it has a wide range of operating temperatures (-40°C to 85°C). It is UL 94V-0 rated for flame retardant properties, and has a high surge rating of up to 6000V./s.

Working Principle

ROV05-241K-S-2 is a rotating type varistor based on a high-performance non-linear solid ceramic element, which is connected in series with the protected circuits. A rotating collar assembly causes the current to flow through different sections of the varistor, depending on the rotational angle. This is what allows the device to dissipate large amounts of energy with no permanent damage.

The device works by forming a voltage-dependent electrical path between its terminals, with a very low resistance when the voltage is below the rated clamping voltage. When the voltage exceeds the rated clamping voltage, the applied voltage causes a large increase in current that is dissipated as heat through the rolling elements. This then reduces the voltage by a specified amount once the current dissipates, allowing the equipment to continue operating safely.

The device also has an internal resistance, which help to limit current, and a leakage current, which is the amount of current that flows even when the varistor is not activated. This helps to reduce the risk of overloading and damage to the system.

ROV05-241K-S-2 is designed to dissipate large amounts of energy in short durations, and protect the system from large over voltages. It is the most suitable option for applications which require protection from transient voltage conditions, and can be easily incorporated into new and existing systems.
