【正文】 EX: 純 ISDN產(chǎn)品 , DI300 Building Networks for People ? TNV2 Circuits Tele 產(chǎn)品之相關(guān)規(guī)定 whose normal operating voltages exceed the limits for an SELV CIRCUIT under normal operating conditions for telephone ringing signals, voltages such that the signal plies with the criteria of either clause (for Europe) or clause (for US). 一般而言 , TNV2 的線路是針對連接至 indoor tele 線路 , 且會 產(chǎn)生震鈴訊號高於 SELV ( or 60Vdc), 此類型產(chǎn)品必須做Annex 和 。角的傾斜面上時不可 產(chǎn)生失衡現(xiàn)象及造成使用者及維修人員 產(chǎn)生危險之情形 . 9. Impact Test Requirement : 以一直徑 50mm, 重為 500177。3% Period : 48 Hours 然後做 HiPot Test Building Networks for People 安規(guī)主要設(shè)計要求 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)計要求 5. 防火等級 : 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% 來作為測試的範(fàn)圍 . 100240V, 5060Hz, 1A = 測試點為 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。 60/50 Hz 。Building Networks for People 產(chǎn)品安規(guī)設(shè)計 之 要求與測試 Prepare by : 品質(zhì)工程部 / Gemmy Liu Building Networks for People General Principles IEC 60950 標(biāo)準(zhǔn)主要是在防止人體受到下述危險之傷害 : Hazards E
