The V385LT40BPX10 is a highly dependable Type 2+ Varistor, Metal-Oxide Varistor (MOVs) device designed to provide transmission line protection against power surges. It is a state-of-the-art MOV with a wide operating temperature range of -55 to +120°C. It offers a higher surge rating than other MOVs, and is ideal for applications in computer and communications applications.

The V385LT40BPX10 is composed of a silicone coating over a ceramic body. The ceramic body is comprised of zinc oxide particles which are electrically interconnected and bonded together by a silicone rubber binding. This structure provides high electrical insulation, superior low-voltage performance, and environmental stability.

The V385LT40BPX10 is ideal in power systems and communication applications to provide circuit protection against transients such as lightning, power supply faults, and other over-voltage conditions. It is available in two versions, one with a fixed voltage rating of 375VAC, and the other with a nominal voltage rating of 385VAC. The V385LT40BPX10 is soft-start, which means it reduces line voltage percentage rise in the event of a fault. It protects against voltage spikes that cause large inrush currents, which can damage communication and power systems.

The working principle of the V385LT40BPX10 is based on the metal-oxide varistor theory. When connected to an AC line, the voltage across the Varistor is regulated by the RC time constant of the metal-oxide pellet. When a voltage spike occurs, the Varistor quickly absorbs the excess energy and limits the voltage rise on the load side of the device. This ensures the electronic circuitry is not damaged by over-voltage.

The V385LT40BPX10 is qualified for automotive and military applications and is compliant to various UL standards. It is also compliant to IEC 61000-4-2 (EFT) and IEC 61000-4-5 (surge) standards. It is small in size and is designed for space saving due to its compact size, which makes it ideal for many types of applications. Additionally, its low temperature coefficient guarantees signal and data integrity.

The V385LT40BPX10 is a dependable, space saving, and cost-effective solution for over-voltage protection. It provides reliable and rapid response for a wide range of AC and DC power systems, including industrial, telecommunications, and computer equipment. It offers excellent surge withstanding up to 20kV, ensuring protection of your sensitive equipment from electrostatic discharge and other voltage related faults. It is an ideal choice for all types of applications where high performance, reliability, and cost-effectiveness are required.
