Varistors, sometimes referred to as Voltage Dependent Resistors (VDRs), are essential components in a wide range of applications involving power electronics protection. This article takes a look at the application field and working principle of the V130LS1 varistor.

Varistors can be found in many different types of applications, including power tools, automotive electronics, communication electronics, and consumer appliances; they are also used in surge protection applications. Due to their low cost and versatility, varistors are an ideal choice for voltage and current overshoot protection as well as voltage control in power supply systems.

The V130LS1 is a metal oxide varistor (MOV) designed for use in AC/DC power supply and overvoltage protection applications. It has a maximum working voltage of 130V and features excellent surge current handling abilities. The V130LS1\'s linear, low-impedance design is ideal for UPS applications, enabling it to quickly and accurately respond to various types of overvoltage signals. This makes it an invaluable component for preventing equipment from being damaged due to sudden overvoltage.

The V130LS1\'s design is based on a monolithic ceramic structure with integrated metal oxide layers and spark gaps. The metal oxide layer is comprised of zinc oxide, which forms a non-linear resistor network; this consists of multiple, uniformly distributed electrodes, separated by a spark gap. These spark gaps form an integral part of the V130LS1\'s design, as they enable the varistor to interrupt an overvoltage signal before it can reach the equipment, thereby preventing any damage.

The basic working principle of the V130LS1 is based on its voltage-dependent features. When the applied voltage is below the MOV\'s rated voltage, the core is in its \'open\' state and exhibits a low impedance. When the voltage increases beyond the rating, the electrodes are repositioned and cause the core to become \'closed\', temporarily blocking the signal. This effectively interrupts the surge energy and prevents it from reaching the equipment.

In order to fulfill its purpose, the V130LS1 must maintain a low impedance for most applications. It also needs to have a robust design that can withstand high surge currents, as this directly affects its ability to properly protect circuitry. The varistor\'s robust construction and capability to maintain a low-impedance even under high surge currents have made it a popular choice in power electronics and overvoltage protection applications.

The V130LS1 also features a wide-operating temperature range, making it suitable for use in industrial and commercial environments. Its robust construction, wide operating temperature range, and versatility make the V130LS1 an ideal choice for overvoltage and power supply protection applications.
