Since varistor has the characteristics of aging or degrading; MPTFMOV can separate the varistor from the main circuitry by opening the thermal protection component when the varistor (MOV) degrades or fails. It is often used in which requires high reliability and weather withstanding, such as photovoltaic inverters, communication equipment, and power supplies in data centers, etc. Compliant ## **Approvals** UL1449 4th Edition TUV IEC/EN 61643-11 IEC/EN 61643-31 ## **Applications** - Telecom Equipment - String Inverter in Photovoltaic System - AC / DC Power Supply - Uninterruptable Power Supply (UPS) - Surge Protective Device (SPD) - Electric Meter ## **Features** - Thermal Protection, High Reliability - Small Size - Remote Signal Contact for Failure Indication (Optional) - High Energy Capacity - Epoxy Sealing Material, Flame-retardant to V0 (UL 94) - Comply with UL 1449 / IEC 61643-11 - Power Distribution Unit (PDU) ## **Diagram** ## **Schematics** Dimensions : Millimetres Newark.com/multicomp-pro Farnell.com/multicomp-pro sg.element14.com/b/multicomp-pro 11/11/24 V1.1 Page <1> ## **Thermally Protected Varistors** ## **Operation Principle** ## **Thermal Protection** Figure a is a surge protection circuit commonly used in power supplies. MOV is used to suppress the surge voltage and protect the subsequent circuit. There is a risk of burning when the varistor degrades or fails. In the high-reliability surge protection circuit of Figure b, in order to improve the safety of the circuit, a thermal protection varistor MPTFMOV is used as the surge voltage protection element. MPTFMOV is a combination of varistors (MOV) and thermal protection component. When the temperature of the MOV is abnormally exceeded, the thermal fuse will be opened first, so that the failure mode of the MOV appears to be open-circuit failure. **==> picture [46 x 8] intentionally omitted <==** **----- Start of picture text -----**
