A static transfer switch's principal function is to ensure trouble-free and safe changeover from utility power to standby power. Additionally, it preserves the isolation of one source from the other while performing this switch.
Static Transfer Switches are crucial components for boosting the resilience and minimising downtime in any mission-critical electrical infrastructure. It is widely used in data centre environments with a two-node setup to provide redundancy for devices that do not have multiple power supplies. Typically fed by two independent UPSs or a group of UPSs, they effortlessly shift the important load between UPSs for maintenance purposes or in the event of a complete failure of one of the supplies.
They can provide the next degree of redundancy inexpensively for essential installations when 2N configuration is not available and infrastructure changes would be excessively expensive and disruptive to company operations. They are available in a variety of configurations, ranging from small DIN-rail-mounted units to single-phase bypass switches for industrial applications, rack-mounted single and three-phase static switches for telecommunications and data centre applications, to wall-mounted and freestanding single and three-phase static switches for protecting entire departments or critical infrastructure.
Our Solid-State-Static-Transfer-Switch transfers load effortlessly between sources. The iSTS is entirely solid-state and incorporates intelligent features that optimise switching between asynchronous supply and load transfer for inductive and non-linear loads.
