Classes of Static Transfer Switches for Uninterruptible Power Supplies


In current data centers, you can use a Static Transfer Switch (STS) to give the power systems the option of switching input sources automatically without interruption. With an STS, you eliminate the chances of loss of power because of critical loads. You achieve this by it coordinating correctly with your electrical distribution system.

You can find both manual and automatic switch transfers. The automatic STSs get triggered after sensing one of the sources has gained or lost power. Read on to learn more about static transfer switch for Ups.

Large STSs

These STSs have an in-built bypassing system made up of 6 draw-out or plug-in circuit breakers to enable you to conduct routine maintenance of your electronics. You can use them on all critical applications where you should have continuity of power. This can help you keep your critical loads up every time.

These switches come with a list of alarms and status that can help you detect any problem in advance. You can use large STSs in traffic control sites, data centers, and process control. They also help in maintaining power to weapons and radar systems, especially in navy vessels.

Point of Use STSs

Also known as the rackmount static transfer switches (RMSTS), they come with extensive monitoring and user communication options. Here, the only difference between this switch and the large STSs is in terms of size. They’re reduced in size to fit rack mounting dimensions in point of use application.

By choosing this type of static transfer switch for Ups, you enjoy many functional advantages because of their mobility and closeness to the load. You also don’t need to run a unique conduit for a relocation because you can use any power feeder source.
