The ROV10-560K-S-2 is a Type 2 Surge Protective Device (SPD) with a 10/20 µs waveform current rating of 560A. It is used mainly in telecommunication applications to protect against lightning and transient voltage surges. This device is a part of a larger family of SPDs, all of which fall into the category of TVS (Transient Voltage Suppressor) - Varistors, MOVs (Metal Oxide Varistor). Surge protective devices are important components which help to guard electrical and electronic systems from the damaging effects of high voltage transients which can occur from various sources such as lightning strikes nearby. In the telecommunications industry, there is a need to protect the copper cables, wireless communication equipment and the various nodes, repeaters and other equipment from spikes and surges in electricity caused by external environmental factors such as lightning, storms, etc. Surge protectors such as the ROV10-560K-S-2 help to isolate these effects and protect electronic systems and components from voltage spikes and current surges which could otherwise affect the performance and efficiency of the system. The ROV10-560K-S-2 utilizes an arc suppression method to effectively reduce the effects of high voltages as well as high power and energy. So how does the ROV10-560K-S-2 work exactly? The ROV10-560K-S-2 is designed with a series of components and features which work together to protect against voltage spikes and current overloads. This device utilizes a non-linear discharge circuit, an overvoltage protection circuit, and an overcurrent protection circuit which all work together to effectively limit the amplitude and duration of surges. The non-linear discharge circuit is composed of a metal oxide varistor (MOV) that is used to reduce the amplitude of surges. The MOV acts like a variable resistor and acts to abruptly reduce the amplitude of the surge in order to protect against damaging currents. The overvoltage protection circuit is composed of a gas discharge tube (GDT) and a spark gap. The GDT is used to limit the peak voltage of the surge while the spark gap helps protect against very high voltage surges. The overcurrent protection circuit utilizes a current limiter, which acts to limit the amount of current that can flow through the device at any given time. This helps protect against overloads which can otherwise damage critical electrical components. In conclusion, the ROV10-560K-S-2 is an important Type 2 SPD which helps to protect against voltage spikes and current surges. This device utilizes a series of components and features which work together to limit the amplitude and duration of surges in order to protect critical equipment. It is an important part of the larger family of TVS - Varistors, MOVs and helps to ensure the safety and reliability of telecommunications systems.
