二、美國AMETHERM部分產品介紹
1.AMETHERM浪涌電流限制器MM35-DIN系列
浪(lang)(lang)涌電(dian)(dian)(dian)(dian)流高是(shi)電(dian)(dian)(dian)(dian)氣(qi)設備在初始加電(dian)(dian)(dian)(dian)期(qi)間汲取的(de)(de)最(zui)大(da)瞬時(shi)輸入電(dian)(dian)(dian)(dian)流的(de)(de)結(jie)果。隨著技術的(de)(de)不(bu)斷發展，當今大(da)多(duo)數系(xi)統都可(ke)以高效運行并保持低阻抗，進而導(dao)致高浪(lang)(lang)涌電(dian)(dian)(dian)(dian)流。浪(lang)(lang)涌電(dian)(dian)(dian)(dian)流限制器(qi)用(yong)于減少在打開電(dian)(dian)(dian)(dian)氣(qi)設備時(shi)發生(sheng)的(de)(de)浪(lang)(lang)涌電(dian)(dian)(dian)(dian)流。AMETHERM的(de)(de)MM35-DIN系(xi)列浪(lang)(lang)涌電(dian)(dian)(dian)(dian)流限制器(qi)具有在680V RMS時(shi)從50A到(dao)80A的(de)(de)連(lian)續電(dian)(dian)(dian)(dian)流額定值和1,200焦耳的(de)(de)能量，可(ke)以應對工業環境中發現(xian)的(de)(de)高功(gong)率水平。

2.AMETHERM熱敏電阻CL20系列
CL20系列PTC熱(re)敏(min)電(dian)(dian)(dian)(dian)阻在(zai)高壓應(ying)用中提供穩(wen)定(ding)性和可靠性，可承受數(shu)百(bai)次最大浪涌電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)沖擊(ji)，而不(bu)會降低(di)性能。PTC熱(re)敏(min)電(dian)(dian)(dian)(dian)阻不(bu)需要復位時間(jian)，因此在(zai)重(zhong)復使用期間(jian)不(bu)會產生(sheng)大的(de)(de)(de)浪涌電(dian)(dian)(dian)(dian)流(liu)(liu)，因為它們(men)的(de)(de)(de)電(dian)(dian)(dian)(dian)阻保持在(zai)高狀態。CL20系列PTC熱(re)敏(min)電(dian)(dian)(dian)(dian)阻的(de)(de)(de)器件具有22.5 mW /°C的(de)(de)(de)耗散常(chang)數(shu)，2.0 J /°C至(zhi)3.45J /°C的(de)(de)(de)熱(re)容(rong)，+ 120°C的(de)(de)(de)轉變溫度和65 s的(de)(de)(de)熱(re)時間(jian)常(chang)數(shu)。這些PTC熱(re)敏(min)電(dian)(dian)(dian)(dian)阻的(de)(de)(de)開關電(dian)(dian)(dian)(dian)流(liu)(liu)和連續電(dian)(dian)(dian)(dian)流(liu)(liu)分別為450 mA至(zhi)1750 mA和225 mA至(zhi)850 mA。它們(men)還(huan)提供容(rong)易(yi)的(de)(de)(de)PCB安裝，直(zhi)徑為22毫米(mi)(mi)，直(zhi)引(yin)線，并(bing)且大多數(shu)帶有可選的(de)(de)(de)外(wai)部或內部扭結引(yin)線。Ametherm還(huan)提供直(zhi)徑從6毫米(mi)(mi)到(dao)20毫米(mi)(mi)的(de)(de)(de)較小PTC電(dian)(dian)(dian)(dian)路保護設備(bei)。

3.熱敏電阻探頭組件PANR系列
AMETHERM的PANR系(xi)列熱敏電阻(zu)探(tan)頭組件(jian)(jian)由特殊配方的金屬氧(yang)化物陶(tao)瓷(ci)材(cai)料(liao)制成，該材(cai)料(liao)在(zai)檢測溫度(du)方面極為精確。PANR探(tan)頭組件(jian)(jian)可(ke)用(yong)于具有(you)定制設計(ji)功能的各種外殼中(zhong)，于變壓器，電動機，空氣(qi)傳感器和(he)HVAC系(xi)統。環形接線端子可(ke)實(shi)現簡(jian)單(dan)而牢固(gu)的表(biao)面安裝，為PT100 RTD和(he)熱電偶提供高穩定性替代品，與(yu)其(qi)初始電氣(qi)值(zhi)之間的漂移最小。

4.AMETHERM浪涌電流限制器bigAMP系列
AMETHERM的(de)(de)(de)bigAMP浪涌(yong)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)限制器是(shi)專門設計(ji)的(de)(de)(de)熱(re)敏(min)電(dian)(dian)(dian)(dian)(dian)阻(zu)，能(neng)夠承受(shou)高達36安(an)培(pei)的(de)(de)(de)連續電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)和260焦耳的(de)(de)(de)輸(shu)入能(neng)量(liang)。當電(dian)(dian)(dian)(dian)(dian)氣設備開啟時(shi)，bigAMP浪涌(yong)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)限制器會吸收(shou)大(da)量(liang)浪涌(yong)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，方(fang)法(fa)是(shi)對電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)提供高電(dian)(dian)(dian)(dian)(dian)阻(zu)，一旦(dan)穩態(tai)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)開始流(liu)(liu)過(guo)熱(re)敏(min)電(dian)(dian)(dian)(dian)(dian)阻(zu)，電(dian)(dian)(dian)(dian)(dian)阻(zu)就會迅速減(jian)小。在(zai)(zai)開關電(dian)(dian)(dian)(dian)(dian)源中(zhong)，瞬(shun)時(shi)浪涌(yong)能(neng)量(liang)是(shi)由較大(da)的(de)(de)(de)輸(shu)入濾(lv)波電(dian)(dian)(dian)(dian)(dian)容器和交流(liu)(liu)輸(shu)入電(dian)(dian)(dian)(dian)(dian)壓引起的(de)(de)(de)。在(zai)(zai)吸收(shou)能(neng)量(liang)的(de)(de)(de)過(guo)程中(zhong)，熱(re)敏(min)電(dian)(dian)(dian)(dian)(dian)阻(zu)的(de)(de)(de)初始高電(dian)(dian)(dian)(dian)(dian)阻(zu)在(zai)(zai)幾(ji)毫秒內下降到可以(yi)忽(hu)略(lve)不計(ji)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)阻(zu)，以(yi)準備允許高水平的(de)(de)(de)穩態(tai)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)流(liu)(liu)過(guo)而電(dian)(dian)(dian)(dian)(dian)路(lu)中(zhong)的(de)(de)(de)功率(lv)損耗(hao)最小。bigAMP浪涌(yong)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)限制器將吸收(shou)高達260焦耳的(de)(de)(de)輸(shu)入能(neng)量(liang)，并攜帶(dai)36安(an)培(pei)的(de)(de)(de)穩態(tai)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)。
