Temp. : 20 ~30℃ Humidity : 95%177。3% Period : 48 Hours 然後做 HiPot Test Building Networks for People 安規(guī)主要設(shè)計(jì)要求 4. 距離要求 (絕緣 ) Secondary Primary D B O TNV B(S) D B(S) D : Double( Reinforced) S : Supplementary B : Basic O : Operational(Functional) Building Networks for People 安規(guī)主要設(shè)計(jì)要求 5. 防火等級(jí) : 945V, 94V0, 94V1, 94V2, HF1, HF2, HB, HBF Internal Plastic Part Material flammability rating minimum 94V2 Enclosure flammability rating minimum 94V0 Building Networks for People Building Networks for People 依 Input Power Rating +6%, 10% 來作為測(cè)試的範(fàn)圍 . 100240V, 5060Hz, 1A = 測(cè)試點(diǎn)為 90V/ 50Hz 及 60Hz 254V/ 50Hz 及 60Hz If the rated voltage is 230V single phase or 400V three phase the tolerance shall not be less than +10% and 10% 判定 : not exceed the rated current by more than 10% under normal load. 1. Input Test 安規(guī)主要測(cè)試要求 Building Networks for People 1. Input Test Building Networks for People 適用情形 : 有開孔之外殼 A. 上蓋之開孔 i) not exceed 5mm in any dimension. ii) not exceed 1mm in width regardless of length iii) be so constructed that direct, vertical entry of a falling object is prevented from reaching such bare parts by means of trap or restriction.(如下圖例 ) (圖例 ) EX: 左圖之綠色虛線部分不可超過５ mm 2. Accessibility Test : Building Networks for People B. 側(cè)邊之開孔 a. not exceed 5mm in any dimension. b. not exceed 1mm in width regardless of length. c. 開孔位置適當(dāng) , 並在其 5176。 角範(fàn)圍內(nèi) , 無具危險(xiǎn)電 壓零件存在 . 投影 5176。角範(fàn)圍的定義 (如下頁(yè)附圖 ) 2. Accessibility Test : Building Networks for People 以類似百葉窗的開孔方式 , 使其 5176。角的投影範(fàn)圍內(nèi)無危險(xiǎn)電壓零件 2. Accessibility Test : Building Networks for People C. 底部之開孔 因目前廠內(nèi)許多產(chǎn)品皆是共用 case, 在 safety st
