Power Line Transient Test (Iec 61000-4-4 Fast Transients/Burst); Peak Voltage; Polarity; Repetition Frequency Of The Impulse: 5 Khz - Hitachi CML174SXW2 Service Manual

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 50Ω 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: 5 KHz.

8.4 Rise-Time: 5ns

8.5 Impulse Duration: 50 nS

8.6 Relation to Power Supply: Asynchronous

8.7 Burst Duration: 15 ms

8.8 Burst Period: 300 ms

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 is AC 240V.
Note :
8.10.1
IEC 61000-4-4 defines that power supply, I/O line and control line all shall perform the
transient test. The I/O line and control line is applied with only half of peak voltage (1
KV).
8.10.2
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 50Ω to monitor the rise-time,
impulse, duration and repetition rate of the impulses within one burst.
