Ensuring safety, reliability, and minimal downtime

07Mar

An automatic transfer switch (ATS) is a means of transferring power between a primary electrical power source and an alternative source, such as a generator, in the case of power failure.

Automatic transfer switches are critical for the smooth, consistent operation of facilities that require near-constant uptime. While manual transfer switches require an operator, and pose a variety of safety and time management concerns, an ATS can sense critical shifts in electrical power, such as the loss of the power source, or when voltage frequency varies from a preset limit, and automatically transfer power from the alternate source. Additionally, an ATS can detect when power is restored in the primary source, and retransfer the load back.
