Scope

This standard specifies the ripple immunity test method for DC power input ports of electrical and electronic equipment. This section applies to low-voltage direct current power supply ports of equipment powered by external rectification systems or batteries being charged. The purpose of this standard is to establish a general and reproducible basis for the immunity of electrical and electronic equipment under laboratory conditions to the ripple voltage superimposed on the d.c. disturbance test. This standard specifies: - the waveform of the test voltage; - the range of test levels; - the test generator; - the test configuration; - the test procedure. The following test requirements apply to electrical and electronic equipment and systems. When the rated power of the equipment under test is greater than the capacity of the test generator described in Clause 6, this test is also applicable to its components or subsystems. This test does not apply to equipment powered by battery charging systems switched in switch mode. This section does not specify tests for special equipment or systems. The main purpose of this part is to provide a general basic basis for relevant professional standardization technical committees. Relevant professional standardization technical committees (or users and manufacturers) are responsible for selecting appropriate test items and severity levels for their equipment. Special test procedures are applicable to special electric or electronic equipment, such as equipment connected to the DC power supply network of telephone exchange centers; relevant professional standardization technical committees should evaluate the relevance and applicability of the test procedures given in this basic standard.
