ROV14-201K-2

Surge protection devices (SPDs) are used to protect equipment and machinery from transients, such as electrostatic discharge (ESD) and lightning strikes. The ROV14-201K-2 is an industrial grade varistor that is commonly used in these applications. Varistors, also known as Metal Oxide Varistors (MOVs), are one type of surge protection device. In this article, the application field and working principle of the ROV14-201K-2 will be discussed.

Varistors are voltage-dependent, non-linear resistors that are used to protect sensitive electronic circuitry from overvoltage transients. They are able to do this by clamping the voltage to a known level and dissipating the excess energy as heat. The ROV14-201K-2 is an industrial grade varistor that is UL1449 4th edition certified for use in industrial and commercial applications. It is rated for a maximum continuous operating voltage (Vc) of 272 VAC and a maximum surge protection of 10kA. It is also designed for reliable performance in temperatures ranging from -40°C to +85°C.

The ROV14-201K-2 is typically connected between the phase and ground of a power line. When a transient surge occurs, the varistor begins to conduct. The MOV is essentially a voltage-dependent resistor, which means that its resistance is very high until a certain voltage level is reached. When the voltage reaches that level, the resistance rapidly drops, allowing it to conduct and absorb the energy of the surge. In this way, the surplus energy is dissipated as heat, and the protected circuit remains undamaged.

The ROV14-201K-2 can also be used to provide protection from other electrical transients. It is capable of providing protection from line-to-ground transients up to 1100 V and line-to-line transients up to 2000 V. This makes it an ideal choice for industrial-grade surge protection applications. In addition, its low impedance design ensures low insertion loss and tight voltage control.

The ROV14-201K-2 is an industrial-grade varistor and a reliable option for surge protection applications. It is able to provide robust protection from ESD and lightning strikes, as well as other electrical transients. Its low insertion loss and wide operating temperature range make it an ideal choice for industrial applications.
