WMZ11A型PTC熱敏電阻

1.應(yīng)用范圍:
   WMZ11A型PTC熱敏電阻用于各種熒光燈電子鎮(zhèn)流器、電子節(jié)能燈中,不必改動線路,將適當(dāng)?shù)臒崦綦娮柚苯又锌缃釉跓艄艿闹C振電容器兩端,可以變電子鎮(zhèn)流器、電子節(jié)能燈的硬啟動為預(yù)熱啟動,使燈絲的預(yù)熱時間達(dá)0.4~2秒可延長燈管壽命三倍以上。

2.特點:
   WMZ11A型PTC熱敏電阻利用材料PTC特性制作而成,產(chǎn)品體積小、耐電壓高、壽命長、正常工作時功耗小。

3.應(yīng)用原理:

?? WMZ11A型PTC熱敏電阻應(yīng)用PTC熱敏電阻實現(xiàn)預(yù)熱啟動原理如右圖所示:剛接通開關(guān)時,R t 處于常溫態(tài),其阻值遠(yuǎn)遠(yuǎn)低于C 2 阻值,電流通過C 1 ,R t 自熱溫度超過居里點溫度T c 躍入高阻態(tài),其阻值遠(yuǎn)遠(yuǎn)高于C 2 阻值,電流通過C 1 、C 2 形成回路導(dǎo)致LC諧振,產(chǎn)生高壓點亮燈管。
