1 Thermally Protected MOVs (TMOV) Product Catalog 产品手册 Xiamen SET Electronics Co., Ltd 厦门赛尔特电子有限公司 November. 2010

2 Introduction of Thermally Protected MOV 热保护压敏电阻介绍 SET Thermally protected MOV (Abbreviated TMOV) is a new patent technology in the field of surge protection. The TMOV is a fail-safe device, which integrated a disk varistor and a thermal fuse in a single package. The thermal fuse is designed to disconnect the MOV from the circuit, in case of MOV s failure. Because the MOVs might thermally run away due to the increasing leakage current, or burn and burst in the event of a shortcircuit fault. The TMOV can offer faster response owing to its good thermo-coupling with the physical body of the MOV, comply with UL1449 3rd, IEC , IEC , GB and ROHS compliant. The TMOV can substitute the standard MOV and provide enhanced security, never fire or burn, suitable for type 2 SPDs, Type 3 SPDs, AC Power supplies, Solar control panel and etc. SET TMOV series have two versions: one has three lead wires with indication of MOV s failure, another has five lead wires with indication and isolated remote signal. Both versions are ROHS compliant and wave solderable. 赛尔特 ( 简称 TMOV), 是合金型温度保险丝与压敏电阻的聚合体, 具有过电压过电流和过温多重保护功能的专利产品 ; 本产品的压敏电阻具有高热容量和优良的过电压耐受能力, 内置温度保险丝的很低内阻特性造就了其具有与压敏电阻 I MAX 相符的通流量, 确保了 TMOV 整体浪涌抑制能力, 通过压敏电阻与温度保险丝紧凑的结构设计达到优良的热传导性能, 确保了压敏电阻在各种过电压情况下失效后能迅速从电路中脱离, 有效避免了火险隐患本产品符合 UL1449( 第三版 ),IEC ,IEC 和 ROHS 等标准要求随着安规标准要求的不断提升,TMOV 高可靠的安性能较普通压敏电阻更适合应用于各类电源防雷器防雷插座电源适配器消费类电子电源及太阳能风能铁路等领域赛尔特 TMOV 系列产品均具有状态指示接点, 且 20S 25D 25S 34S 系列产品还可具有独立遥信功能接点 ( 型号后缀 -IT) TMOV 产品安装于电路板时, 可采用波峰焊工艺 2
