KS X 3126 EMC Testing of Broadband Data Transmission Systems
The KS X 3126 EMC test standard, previously known as KN 301-489-17, defines test methods for immunity to ripple at the d.c. input power port of electronic and electrical equipment. KS X 3126 compliance testing applies to certain low-voltage d.c. power ports of equipment. This specific equipment is supplied by external rectifier systems or batteries that are being charged.
The object of KS X 3126 testing is to establish a reproducible but common basis for testing, in a laboratory, electronic and electrical equipment that is subjected to ripple voltages. These voltages are similar to those generated by rectifier systems and/or auxiliary service battery chargers overlaying on d.c. power supply sources.
The KS X 3126 EMC test standard defines several criteria. These include but are not limited to:
- The test voltage waveform.
- The range of test levels.
- The test setup.
- The test generator.
- The test procedure.
The KS X 3126 EMC standard test procedure applies to electrical or electronic systems and equipment. It also applies to modules or subsystems whenever the equipment under test (EUT) rated power is greater than the test generator capacity specified in the compliance testing document.
The South Korean EMC test does not apply to equipment connected to battery charger systems that incorporate switch-mode converters. KS X 3126 lab testing does not specify the tests to be applied to particular apparatus or systems. The primary objective is to give a general basic reference to IEC product committees.
These KS EMC product committees or users or manufacturers of equipment are responsible for the appropriate choice of the test. They are also responsible for the severity level to be applied to their equipment. Dedicated test procedures are in use for testing specific categories of electrical or electronic equipment. Examples of this include equipment connected to d.c. supply network of telephone switching centers.
