What’s SEMI F47?

SEMI F47-0706 is an industry standard for voltage sag immunity. It states that industrial equipment must tolerate voltage sags, or dips, on the AC mains supply to specific depths and duration. It’s an useful standard that many other industries use it, either formally or informally. Equipment that complies with the SEMI F47 has been proven to be more reliable and productive.

How Expensive is SEMI F47 Testing?

It’s quite inexpensive. In most cases, it’s not necessary to add expensive power conditioning devices to the industrial equipment. Instead, Semi F47 testing by Powerside (formerly Power Standards Labs) identifies the weak points, and suggests low-cost or zero-cost solutions. These solutions rane from minor changes in power supply configuration, to software delays, to different relay, or contractor selection.
