ROV05H390K-S Application Field

ROV05H390K-S is mainly applied in the communications, industrial control, military, medical, automotive and consumer industries. For example, it is used to effectively protect the electronic equipments or components from transient voltage surges caused by electrostatic discharge or lighting strikes, etc. It is also widely used to protect phoneline, signal line, LAN, USB, audio line, onboard and power line.

ROV05H390K-S Working Principle

ROV05H390K-S is a surge protection device with Varistor (Metal Oxide Varistor, MOV) technology. This kind of transient voltage surge suppressor is composed of two main parts, the metal oxide varistor and the transient voltage surge clamp. The metal oxide varistor is made of metal oxide and its main component is zinc oxide. When it is working, the voltage will be limited within the limited range and the overflowing current will be diverted to the ground immediately. The transient voltage surge clamp can provide clamping voltage, so that the voltage difference between the two ends will not exceed the clamping voltage.

When a surge or high voltage signal is applied to the varistor, it will immediately reduce the voltage to a safe level, and clamping voltage will be generated at the same time. This voltage will limit all overvoltage and transient events, so that the components and equipments can be protected from strong surges. The advantage of using a MOV device is that it can divert larger amounts of energy away from the protected circuits with only a small amount of surge energy going through the circuits.

ROV05H390K-S has many advantages compared with other products in terms of response speed, low clamping voltage, excellent temperature stability and forward voltage. It also has low leakage current and low power losses during normal operation. All these advantages make it become an ideal choice for power transmission and power quality problems.
