VTD - MV Series

The VTD-MV(S) Varistors with Thermal Decoupler use specially shaped metal oxide varistors equipped with thermo decoupling devices. They are widely used in TVSS products, AC/DC power supplies, AC panel protection modules, AC line power supplies, surge protected strip connectors, AC power meters, UPSs (Uninterruptible Power Supplies), inverters, white goods, GFCIs (Ground Fault Current Interrupters). The advantages of the VTD-MV(S) Varistors with Thermal Decoupler are: terminals construction for PCB mounting; a thermal decoupling device which protects the VTD-MV(S) from varistor failure in the event of abnormal overvoltage and can withstand 16Amps (for one disconnector); the VTD-MV(S) also has the remote signalization capability. They can have different voltage values (see VTD-MV) or they can be matched and therefore rated for higher currents or a combination of these new features. The VTD-V(S) products can be used in equipment with different power supplies as it is in personal computers (110V and 230V). You can choose from two, four, six or eight versions with different voltage (between 75Vac to 440Vac). It can be used if we have very sensitive and expensive equipment.
