Abstract

According to one embodiment, an automatic transfer switch (ATS) module for an electronic rack includes a container and four pairs of relays that are disposed within the container, each pair having a first relay connected in series with a second relay. A first two pairs of relays are arranged to connect to a first power source and are arranged to connect to a power supply unit, and a second two pairs of relays are arranged to connect to a second power source and are arranged to connect to the power supply unit. The four pairs of relays are arranged in one of several open-closed configurations, such that in a first open-closed configuration the first source connects to the power supply unit through a first two pairs of relays and in a second open-closed configuration the second source connects to the power supply unit through a second two pairs of relays.

Description

technical field [0001] Embodiments of the present disclosure generally relate to automatic transfer switches (ATS) for electronic racks. Background technique [0002] Large clusters of computer servers can be kept in dedicated equipment, usually in rack-mount enclosures. Servers can be used to support the data center industry. In order to enable server functions, a power supply unit (PSU) is used to power the server and thus is an essential element of a rack cabinet. Specifically, the PSU converts power (eg, alternating current) from a utility, such as an alternating current (AC) power source, into regulated direct current (DC) power that is provided to the server. Therefore, PSU resiliency is a high priority, especially in critical facilities where servers may be running 24 hours a day, 7 days a week, such as hospitals and data centers. [0003] A common practice to increase resiliency is to install one or more primary PSUs with at least one additional PSU installed in t...
