ROV14H820K-S-2 Datasheet/PDFROV14H820K-S-2 Application Field and Working Principle
Transtel ROV14H820K-S-2 is part of a wide range of surge protectors that are part of the Varistors, MOVs family of TVS (Transient Voltage Surge) products. These surge protectors provide reliable protection for industrial and automotive electronic components such as controllers, drives, AC/DC power supplies, and displays.
The surge protectors are designed to effectively limit a wide range of transient voltage surge events by using an adjustable surge clamping voltage. The surge protectors feature a low capacitance design that reduces the risk of damage due to capacitive coupling. The devices also provide fast action protection in less than 20 ns for high energy surges.
The ROV14H820K-S-2 Varistor is a surface mount, three lead device that is available in two different sizes. The first is a 30A, with an operating voltage range of 14V to 85V. The second size is a 50A, with an operating voltage range of 8V to 20V. Both sizes have a clamping voltage of 700V.
The working principle of the Varistor is based on the capacitive behavior of a zinc oxide element. When a surge is applied, the zinc oxide element is able to absorb a large amount of energy, reducing the voltage level to a safe level. The Varistor is designed to limit the voltage to a predetermined value regardless of the level of the surge.
The Varistor is also designed to provide reliable protection on both continuous and repetitive transient surges. The device will self-reset after the surge event. The surge protectors have a low temperature rise and low inrush current, providing reliable and safe operation.
The surge protectors are designed for use in a variety of industrial and automotive applications. They can be used for data line protection, EMI filtering, and over voltage protection. They have a wide temperature range of -40°C to +125°C, making them suitable for a wide variety of applications.
Overall, the Transtel ROV14H820K-S-2 is an effective and reliable surge protector for a wide range of applications. It provides fast action protection and low capacitance design, making it ideal for protecting sensitive electronic components. The device is available in two different sizes, allowing for optimal protection depending on the application.
