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.

20%
7.8
Burst Period: 300 ms
±
20%
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
7.10.2
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).
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
Ω
to monitor the rise-time,
impulse, duration, and repetition rate of the impulses within one burst.
