智能型零功率PTC熱敏電阻器 產(chǎn)品特點(diǎn)FEATURES 智能型無(wú)功耗PTCR作為電子鎮(zhèn)流器、節(jié)能燈預(yù)熱軟啟動(dòng)元件，能大大地提高燈管的開(kāi)關(guān)次數(shù)和使用壽命，同時(shí)克服了普通PTCR在電子鎮(zhèn)流器、節(jié)能燈預(yù)熱啟動(dòng)后升溫、有功耗的缺點(diǎn)，從而提高了燈的光通量、發(fā)光效率等，堪稱綠色照明電器又一次突破性革命。 As the preheating and softly-starting component of the electronic ballasts and energy-saving lamps, the intelligent PTCR without power consumption can greatly increase the light switching time and operating time. Meanwhile, it can overcome the disadvantage of temperature-rising after preheating and starting of the electronic ballasts and energy-saving lamps, therefore improve the amount of the flowing light and the lighting efficiency of the lamps. It can be considered as another breakthrough revolution of green illumination electric appliances. 典型應(yīng)用TYPICAL APPLICATIONS 電子鎮(zhèn)流器和節(jié)能燈預(yù)熱啟動(dòng)preheating and starting of electronic ballasts and energy-saving lamps 工作原理： 智能型零功率PTC熱敏電阻器是由電壓開(kāi)關(guān)元件與PTC熱敏電阻器組合而成的具有復(fù)合功能的智能型元件，在節(jié)能燈、電子鎮(zhèn)流器上起延時(shí)啟動(dòng)作用。利用燈管啟輝電壓高、工作電壓低的特點(diǎn)，選用工作電壓高于燈管工作電壓、低于燈管啟輝電壓的電壓開(kāi)關(guān)元件，在燈管啟輝時(shí)電壓開(kāi)關(guān)元件導(dǎo)通，電流通過(guò)PTC元件使其阻值產(chǎn)生劇烈變化而使燈管點(diǎn)亮，燈管點(diǎn)亮后電壓回落到正常工作電壓，此時(shí)電壓開(kāi)關(guān)元件關(guān)斷不再有電流通過(guò)，該智能型元件不再消耗電能，達(dá)到零功率的目的。 優(yōu)點(diǎn)： 智能型零功率PTC熱敏電阻器的最大優(yōu)點(diǎn)是在燈正常工作時(shí)，不消耗電能使節(jié)能燈、電子鎮(zhèn)流器的效率更高； 由于在工作中PTC元件無(wú)電流通過(guò)因此不會(huì)產(chǎn)生熱量，有利于節(jié)能燈、電子鎮(zhèn)流器的穩(wěn)定工作，壽命更長(zhǎng)。 應(yīng)用： 智能型零功率PTC熱敏電阻器的應(yīng)用與傳統(tǒng)PTC元件應(yīng)用一致。
