泰科电子全新的Raychem电路保护产品系列.LVR系列的PolySwitch可复式组件,额定电压为240V交流,最大容许电压达265V交流,工作电流范围为50-400 mA。新产品的热激活功能能有效保护电源初级和变压器的电流和温度过载,专为在线电压装置而设计。 LVR组件可保护控制板和元器件免受损坏。在次级短路、过载,或电压不正常时,通过限流而提供保护。与一次性保险丝不同,可复式LVR组件能在电流微增而导致温度上升时提供保护。当安装在可能产生热的元器件如磁性组件、功率开关管或大功率电阻的附近时,单
Tyco Electronics’ new line of Raychem circuit protection products, the PolySwitch multi-component part of the LVR series, is rated for 240Vac and has a maximum allowable voltage of 265Vac and a working current range of 50-400mA. The new product’s thermal activation feature effectively protects the primary and transformer current and temperature overloads, designed for on-line voltage devices. LVR components protect the control board and components from damage. In the secondary short circuit, overload, or voltage is not normal, through the current limit and provide protection. Unlike disposable fuses, the retrofit LVR components provide protection against rising temperatures as the temperature rises. When installed in the possible heat of components such as magnetic components, power switches or high-power resistance in the vicinity, the single
