Coupling/Decoupling networks for testing relays and protecting equipment
The CNV 504N5series of coupling/decoupling networks are used to apply slow damped oscillatory waves onto signal/data lines as per EN/IEC 61000-4-18. A capacitor of 0.5uF is specified to couple the pulses on to the lines. Each line has a decoupling inductor of 1.5mH or 3.0mH to protect equipment from being subjected to the test pulse. The disturbance signal used for this test is a damped oscillatory pulse with a frequency of 100kHz or 1MHz, being generated by the EMTEST OCS 500N6 or OCS 500N6F.
The CNV 504N5 series supports voltages of up to 250V AC/DC and a current of up to 4A AC/DC.
