Product Of The Month: Static Transfer Switches

What is a Static Transfer Switch?

Useful Bypass Switch

A Static Transfer Switch (STS) is a device used in power distribution systems to ensure seamless and uninterrupted power supply. A static Transfer Switch's key difference from a mechanical transfer switch is that a static transfer switch doesn't have moving parts.

A Static Transfer Switch (STS) relies on solid-state components to transfer the load between two power sources, typically between the mains/utility power and a backup power source like a generator or an uninterruptible power supply (UPS).

How does an STS Work?

Static transfer switches provide ultra-fast switching between two synchronised input power sources, offering uninterrupted power to your electronic equipment and devices. A static transfer switch will also allow you to have maintenance and repairs completed on your power protection units without the need to shut down critical equipment, offering business continuity.

Why You Need an STS

Maintaining electrical power to your mission critical applications is paramount to keeping your IT systems running. Although uninterruptible power supplies are an important part of your electrical infrastructure, what would happen if the UPS output failed! The ability to switch rapidly from one power source to another is required to keep your systems running smoothly.

These static transfer switches can be set to use source A or B as the primary supply for the critical load, on failure of the selected source the load will be transferred automatically to the alternative source. When the primary source returns, the load will be seamlessly re-transferred to the primary supply.

Single and three phase systems with 3 or 4 pole switching are available with power ratings from 16A to 800A, having manual bypass mechanisms and an LCD screen providing status, metering and alarm information.
