8. Power Line Surge Test (IEC 61000-4-5 Surge)

The climatic conditions shall be within the following ranges:

8.1.1

Ambient Temperature: 15

8.1.2

Relative Humidity: 10% to 75%

8.1.3

Atmospheric Pressure 86kPa(860 mbar)to 106kPa (1060mbar)

Note: The temperature and relative humidity should be recorded in the test report.

8.2.1

Open circuit voltage:

Short circuit current:

8.2.2

Polarity:

8.2.3

Phase shifting:in a range between 0º to 270º versus the AC line phase angle

8.2.4

Repetition rate:at least 1 per minute

8.2.5

Number of tests: at least 5 positive and 5 negative at the selected points.

8.3

The surge will be applied between lines and between lines and ground.

8.4

If not otherwise specified, the surge to power supply circuits shall be applied synchronized

to the voltage phase at the zero crossing and the peak value of the AC voltage wave.

(Positive and negative)

8.5

The surge voltage for test is from 1 KV and increases 1 kV for each step.

8.6

The recommended severity levels for the surge voltage test is 2.0 KV, and without any

degradation or loss of function that is not recoverable due to damage of component or

software allowed.

8.7

C to 35

(1.2 / 50 µs)
