7. Power Line Transient Test (IEC 61000-4-4 Fast

Transients/Burst)

TEST CONDITIONS & PROCEDURE: (Follow IEC 61000-4-4)

Test Condition :

The condition is base on operating with 50 Ω load.

7.1 Peak Voltage:

2 KV (applies the Level 3 typical Industrial Environment” of IEC

61000-4-4)

7.2 Polarity : + / -

7.3 Repetition Frequency of the impulse : 5 KHz.

7.4 Rise-Time : 5ns

7.6 Relation to Power Supply: Asynchronous

7.7 Burst Duration: 15 ms

±

7.9 Climatic Conditions:

- Ambient Temperature: 15 ° C to 35 ° C

- Relative Humidity: 45% to 75%

- Atmospheric Pressure: 86 kPa to 106 kPa

7.10 Test Procedure:

The monitor Display set high-resolution mode, AC input use AC 240V.

Note :

7.10.1

IEC 61000-4-4 defines that power supply, I/O line, and control line all shall be performed the transient test, but the I/O line and control line is applied with only half of peak voltage (1 KV).

7.10.2

For the comparison of wave-shape generated by different generator, so the test must uses a scope with at least 400 MHz bandwidth, and coupled to 50

to monitor the rise-time, impulse, duration, and repetition rate of the impulses within one burst.
