SIST EN 61000-4-17:2001

Overview

SIST EN 61000-4-17:2001 is a European standard developed by CLC, addressing electromagnetic compatibility (EMC) in electronic and electrical equipment. This standard specifies the testing and measurement techniques for evaluating immunity to ripple on d.c. input power ports. It is particularly relevant for equipment using low-voltage d.c. power supplied by external rectifier systems or batteries that are in the charging process.

EMC ripple immunity tests are critical for ensuring that devices can operate reliably in environments with fluctuating d.c. voltages. SIST EN 61000-4-17:2001 enhances the robustness of products by detailing precise test conditions and procedures for measuring susceptibility to voltage ripple interference.

Key Topics

SIST EN 61000-4-17:2001 covers essential topics related to EMC testing for ripple immunity at d.c. input power ports, including:

• Test Voltage Waveform: Defines the shape and characteristics of the test voltage waveform used to simulate ripple.
• Test Levels: Specifies the acceptable range of test voltages and frequencies.
• Test Generator: Outlines the requirements for equipment used to create the voltage ripple.
• Test Set-up: Provides guidelines for configuring the test environment, equipment connections, and operational modes.
• Test Procedure: Details step-by-step methods for performing the immunity tests, ensuring repeatability and reliability.

These topics collectively ensure uniform testing methods across manufacturers and laboratories, supporting reliable EMC compliance.

Applications

SIST EN 61000-4-17:2001 applies broadly across sectors where electrical and electronic equipment are powered via low-voltage d.c. supply ports. Typical applications include:

• Industrial automation systems
• Telecommunications devices
• IT and computing equipment
• Portable and stationary electronic devices powered by battery or rectified d.c. supply
• Battery charging equipment and systems

By following this standard, manufacturers and testing labs can:

• Verify product immunity to power supply ripple disturbances.
• Ensure ongoing operational reliability in environments with variable d.c. power quality.
• Facilitate product certification for EMC compliance within European markets.
• Mitigate risks of malfunctions and downtimes caused by voltage ripple effects.
