8. 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.
8.1 Peak Voltage:
2 KV (applies the Level 3 typical Industrial Environment” of IEC
61000-4-4)
8.2 Polarity : + / -
8.3 Repetition Frequency of the impulse : 5KHz.
8.4 Rise-Time : 5ns
±
30%
8.5 Impulse Duration: 50nS
±
30%
8.6 Relation to Power Supply: Asynchronous
8.7 Burst Duration: 15ms
±
20%
8.8 Burst Period: 300ms
±
20%
8.9 Climatic Conditions:
- Ambient Temperature: 15
°
C to 35
°
C
- Relative Humidity: 45% to 75%
- Atmospheric Pressure: 86kPa to 106kPa
8.10
Test Procedure:
The monitor Display set high-resolution mode, AC input use AC 240V.
Note :
8.10.1
8.10.2
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
(1KV).
For the comparison of wave-shape generated by different generator, so the test must uses
a scope with at least 400MHz bandwidth, and coupled to 50
Ω
to monitor the rise-time,
impulse, duration, and repetition rate of the impulses within one burst.
