What is BS EN 61000-4-17:2011?

BS EN 61000-4-17:2011, also known as Electromagnetic Compatibility (EMC) — Part 4-17: Testing and Measurement Techniques — Ripple on DC Input Power Port Immunity Test, is a technical standard that focuses on testing and measuring the immunity of electrical and electronic equipment to ripple on its DC power input ports.

Understanding the Purpose

The main purpose of BS EN 61000-4-17:2011 is to ensure that electrical and electronic equipment can function properly even when subjected to certain forms of electromagnetic disturbances. DC power supply ports are particularly vulnerable to ripple interference, which can disrupt the normal operation of devices and cause malfunctions or failures.

By complying with this standard, manufacturers can assess the immunity of their equipment to ripple interference and take necessary measures to improve its performance in real-life scenarios where such disturbances may occur. This helps ensure the reliability and safety of electrical and electronic products for users.

The Testing Process

The testing process outlined in BS EN 61000-4-17:2011 involves subjecting the equipment under test to various levels of ripple voltage and assessing its performance. The standard specifies the necessary procedures, measurement techniques, and test setups to accurately evaluate the equipment's immunity to ripple interference.

Ripple voltage is intentionally applied to the DC input power port while monitoring the behavior of the device. The testing covers both continuous and discontinuous ripple, simulating different real-world scenarios. The standard provides guidance on how to measure the effects of ripple on the device's functionality and establish pass/fail criteria based on acceptable performance levels.

Benefits and Compliance

Complying with BS EN 61000-4-17:2011 brings several benefits to both manufacturers and end-users of electrical and electronic equipment. Manufacturers can ensure that their products meet the necessary immunity requirements, making them more reliable and less prone to malfunctions caused by ripple interference.

For end-users, compliance with this standard gives them confidence in the quality and performance of the equipment they purchase. It ensures that the devices will continue to function properly even in environments where ripple interference is present, such as industrial settings or locations with unstable power supplies.

BS EN 61000-4-17:2011 provides a standardized approach for testing and evaluating the immunity of equipment to ripple interference. By following the guidelines set forth in the standard, manufacturers can enhance the overall quality and reliability of their products, while consumers can be assured of using safe and durable electrical and electronic devices.
