TVS - Varistors, MOVs are an important part of the electrical protection circuit. They can avoid breakdown of semiconductor elements and protect equipment and circuits from damage due to excessive flowing currents. The ROV10H180M-2 is a sintered metal oxide Surge Protective Device (SPD), which has been widely used in low voltage surge protection. In this article, the application field and working principle of ROV10H180M-2 will be introduced in detail.

Application field of ROV10H180M-2

• The ROV10H180M-2 is mainly used in low voltage surge protection, such as telecommunications equipment, power equipment, wireless systems, instrumentation, automotive electronics, traffic control systems, industrial automation systems, semiconductor equipment, etc.
• It is also applicable to sensitive electronic equipment such as computers, modems, data and audio equipment.
• It is also applicable to the protection of power lines and household appliances.
• It can also be used in the protection of emergency lighting and electronic control systems.

Working principle of ROV10H180M-2

The ROV10H180M-2 is composed of metal oxide varistor(MOV) block, zinc oxide varistor(ZOV) block, filter technology, the metal oxide varistor(MOV) block and Zinc Oxide Varistor(ZOV) block can protect the connected equipment from surge current and over voltage, especially the spikes that caused by lightning and static. When the voltage exceeds the varistor’s breakdown voltage, it will reduce the overvoltage by clamping voltage. In addition, due to the presence of internal filters, it can reduce the ripple on DC power line and the noise transmission on signal line.

The metal oxide varistor(MOV) and zinc oxide varistor(ZOV) block has fast response time because they have good self-recovery characteristic, so they can respond to surge current and over voltage very fast and provide reliable protection for the connected equipment. In addition, the device also has low residual current under normal working conditions and will not affect the normal work of the system.

The ROV10H180M-2 can be used under different environmental conditions. It can work at the temperature range from-65°C to 125°C in a dry, humid environment. It is also protected by flame-retardant engineering plastic casing and conforms to UL94V-0 fire safety standard.
