Coupling decoupling network
The coupling network has to couple the interference pulses to the lines of a power supply system (AC or DC) or
to signal and control ports of the EUT. Capacitive coupling is the specified coupling mode for surge testing.
8.3.1.
Coupling to ac / dc power supply lines
The surge generator OCS 500N6 has an integrated coupling network in accordance with IEC 61000-4-12. It must
be possible to test with different coupling modes:
Line
→
GND
(source impedance is 12
/ 30
)
Neutral
→
GND
(source impedance is 12
/ 30
)
L + N
→
GND
(source impedance is 12
/ 30
)
Line
→
Neutral
(source impedance is 12

The release of the surge pulses is mostly related to a certain phase angle.
The surge pulses are synchronized to the input signal at the rear Sync-connector.
