UL 508C for Motor Drives has been Withdrawn – Learn About its Replacement UL 61800-5-1

Accelerate global efficiency in your adjustable speed motor drive certifications.

Adjustable speed motor drives in variable speed applications are increasingly being used as a result of the high efficiency and reliability that they offer. These drives provide precise electrical motor control and only use the energy required, unlike fixed speed motor drives that utilize excess energy. Because motors consume most of the energy produced, the control of motors has become particularly important as the desire to reduce energy consumption increases. With the rising demand for adjustable speed motor drives globally, the need to reduce time and cost to market is critical. And understanding applicable standards, as well as necessary testing and certification requirements, can help streamline global market entry.

On Feb 1, 2020, the safety Standard used for adjustable speed electrical power drive systems changed from UL 508C, Standard for Power Conversion Equipment, to UL 61800-5-1, Standard for Adjustable Speed Electrical Power Drive Systems. This educational webinar will cover what this transition means for your motor drives covered under UL 508C and how you can simultaneously expand your product's marketability while reducing product development time and cost.

Objectives:

  • Understand the major differences between UL 508C and UL 61800-5-1 and how you can transition your certification to the new Standard
  • Learn how the alignment of requirements will allow you one investigation that provides certification to UL 61800-5-1, CSA C22.2 No. 274 and a CB certificate or test report to IEC 61800-5-1, helping you reduce costs and time to global markets
  • Introduce the UL spacings tool that can help to determine if the spacings in your adjustable speed electrical power drive products are in compliance with the Standard
