●热保护型压敏电阻(TFMOV)是压敏电阻与热保护脱离部件的组合。压敏电阻存在老化特性,热保护型压敏电阻能够在压敏电阻(MOV)劣化或失效时,通过热保护部件的动作将压敏电阻从主回路中脱离。常用于光伏逆变器,通信设备,机房电源等对可靠性和耐候性要求高的场所。
●TFMOV is a combination of varistors (MOV) and thermal protection component. Since varistor has the characteristics of aging or degrading; TFMOV 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.
