Varistors With Thermal Disconnection / VTDS40 Series

VTDS40 Series

 VTD(S) Surge Protection Devices use square shaped metal oxide varistors equiped with a thermo decoupling device. They can be widely used in TVSS products, AC/DC power supplies, AC panel protection modules, AC line power supplies, surge protected strip connectors, AC power meters, UPS (uninterruptable power supply), inverters, white goods, GFCI (ground fault current interupters).
The advantages of the VTD(S)40 Surge Protection Devices are: terminals construction for PCB mounting, a thermal decoupling device which protects VTD(S) against varistor failure in the event of abnormal overvoltage; VTD(S) also has a remote signalization capability.
