TVS - Varistors, MOVsThe V275LU40AP is a bi-directional overvoltage protector employing voltage dependent varistor (DVTMOV™) technology. It is designed to protect sensitive equipment from voltage transients and surges which can cause system lockout or data corruption. This device is a great solution for both Asynchronous Transfer Mode (ATM) and Ethernet applications.Its working principle is based on the principle of “electromotive force”. When the voltage passing through the device exceeds the maximum working voltage, electrons are forced away from the MOV and a voltage drop occurs in the device. This voltage drop dissipates the excess energy and protects the connected equipment from overvoltage damage.V275LU40AP applications are typically found in industrial systems including telecom, consumer electronics, electric power equipment, medical equipment and digital control .These systems are commonly susceptible to surges, voltage spikes, overvoltage transients or lightning strikes, and need protection from sustained or abnormal voltages.To ensure the device can dissipate the energy and protect the system, it needs to be correctly communicated at all times. This is where V275LU40AP resistance plays a critical role. It is important to understand that the V275LU40AP is designed to help the system cope with sudden and sustained change in the working parameters, however it must not be used as the sole means of preventing system failure.The V275LU40AP is also able to withstand high voltage applications and can endure more than 1500V, making it suitable for protecting against abnormal or excessive system voltages. It is generally used when medium to high over-voltages are expected as it has a higher level of insulation then other varistors.The V275LU40AP device is one of the most common and reliable over-voltage devices used in industrial applications. It is designed to react quickly and withstand even the harshest of conditions. With these characteristics, it is easy to see why it is so often used in a variety of industries. It offers optimal protection for the system and prevents serious damage from occurring. Though it can’t completely prevent any electrical damage it can help limit the damage if a surge or spike occurs, which makes it an invaluable component for any system that needs protection from voltage transients and surges.
