TVS - Varistors, MOVs, are a type of transient voltage surge suppressor, designed to protect sensitive electronic equipment from voltage surges. ROV05-271K-S is an example of this type of device, and its application field and working principle are as follows.

Application Field

ROV05-271K-S is designed for use in applications where overvoltage transients (TVS) or overcurrent transients (MOVs) require protection. This type of protection is often required where the power supply to sensitive electronic equipment is subject to voltage surges over the designed operating range. This type of surge protection device is commonly used in solutions such as LED displays, point-of-sale terminals, industrial and medical equipment, and many other applications where sensitive, low wattage electronics require protection from accidental overvoltage or overcurrent transients.

Working Principle

ROV05-271K-S works on the basis of a multi-layered, conformal coating of thermally conductive particles around a variable resistor element. When exposed to overvoltage or overtemperature transients, the conformal coating reduces the thermal resistance between the resistor element and a thermally conductive heat sink, which dissipates the excess energy. This results in a brief, but highly effective suppression of the transient voltage or current surge, thus protecting the device and any sensitive equipment to which it is connected.

The ROV05-271K-S’s variable resistor element is tuned to the respective operating voltage and temperature of the device connected to it. This ensures that it will operate optimally and respond rapidly to any over-voltage or over-temperature transients, thereby providing reliable protection.

Conclusion

ROV05-271K-S is a type of transient voltage surge suppressor, designed to protect sensitive electronic equipment by rapidly suppressing over-voltage or over-temperature transients. It is commonly used in solutions such as LED displays, point-of-sale terminals, industrial and medical equipment, and many other applications where sensitive, low wattage electronics require protection from accidental over-voltage or over-temperature transients. ROV05-271K-S works on a multi-layered thermally conductive coating, tuned to the respective operating voltage and temperature of the device connected to it, thereby providing reliable protection.
