測試在於驗証產品在電壓下降

 

Test voltage:                     AC Line, 1kV

Polarity:                            Positive / Negative

Impulse frequency:     5 kHz

Duration:                    60 seconds

b)  Surge Testing

Test voltage:                     1kV, 1.2 msec rise time

Polarity:                            Positive / Negative

Angel:                            0∘ / 90∘ / 180∘ / 270∘

Number of surge:           5 Surge / Polarity

Repetition rate             60 seconds

4)  判定標准 (Criteria)

在普通模式下用正極脈沖﹐然後重復用負極脈沖。在正常操作條件下無任何損壞和偏移。

 Positive pulses were applied in normal mode, then repeated using negative pulses. There is no damage incurred or deviation from normal operation condition during the test.

 

5.3.10  Sag / Drop Out Test (Dip)

1)  目的 (Objective)

         此項測試在於驗証產品在電壓下降﹐中斷和變化條件下的免疫性。它規定了產品在可能出現電流波動情況下的性能規格。

These tests are designed to verify immunity for the voltage dip, interrupt and variation. It provides of the product's performance under condition of power fluctuations that may occur.

2)  參照 (Reference)

IEC 61000-4-11    Dip

3)  規格 (Specification)

a)  電壓瞬間下降 Line Voltage Sag

它要求所有單一產品的額定電壓是120V﹐輸入電壓為108V, 在0.5秒內下降到80.5V,然後再回升到108V。
