A Transient Voltage Suppressor (TVS) is used to protect circuits and equipment from transients and overvoltage surges. ROV 20-781K is a type of TVS that functions as a Voltage Dependant Resistor (VDR). Its application field and working principles are generally understood, however, for further clarification, a brief explanation is provided.

The primary application field of ROV20-781K is to provide protection from surges and spikes in AC power lines. Its general purpose is to protect electrical and electronic equipment from environmental events such as lightning strikes, power utility spikes, and electrostatic discharges, all of which have the potential to cause significant damage to the device or system. Devices such as ROV20-781K are connected directly to the AC power lines, and they can be triggered by either excessive voltage or excessive current.

The working principle of the ROV20-781K is based on a unique combination of both MOVs and voltage dependent resistors (VDRs). When subjected to a surge, the MOV sections clamp down and limit the voltage to a predetermined safe level. Once the surge has dissipated, the VDR components (controlled by the integrated thermal element) resume their regular resistance. This process ensures the ROV20-781K provides maximum protection against transient surges, without compromising the safety of the connected hardware.

The advantages of using the ROV20-781K are fairly evident. It provides a high degree of protection against transient surges, spikes, and other power faults, while providing a low-temperature operation and minimal performance degradation. Additionally, it’s highly reliable, with a proven track record of successfully protecting systems and devices from transient surges and other power-related events. Furthermore, it’s a cost-effective solution to protecting equipment from transient surges and other power-related events, making it an ideal choice for both commercial and industrial applications.

In conclusion, ROV20-781K is a versatile and reliable device used to protect systems and devices from transient surges and other power-related events. It’s designed to be connected directly to AC power lines, with an integrated MOV and VDR combination to provide maximum protection. Additionally, it’s reliable, cost-effective, and proven to be successful with protecting hardware. For all these reasons, the ROV20-781K is an ideal choice for any system or device requiring protection from transient surges and power-related events.
