Forty years ago, Cyberex revolutionized power distribution with its invention of the digital static transfer switch (STS). Since then, building on the innovation of ABB engineering and the technological advancements and commissioning of the most extensive installed base of STSs worldwide, the SuperSwitch®4 has evolved. Designed with a ‘true’ fault-tolerant architecture, SuperSwitch®4 ensures there is truly no single point of failure through the use of our patented transfer algorithms and robust electrical components. With an increased MTBDE to an estimated 1.5 million hours, SuperSwitch®4 reliability is unmatched. SuperSwitch®4 redefines power reliability with its exceptional design, serviceability and user-interface.

Reliability through design excellence

The Cyberex brand has been an industry leader in the design and development of mission critical systems that ensure uptime and business continuity for customers across the globe. We recognize that every customer has unique electrical requirements and we work closely with them to develop solutions that solve their most difficult challenges.

For 600A - 1200A, the SuperSwitch®4 is available in the traditional SuperSwitch® ultra-dense design that maximizes usage of physical floor space. Front access is required for operation and removal of serviceable components, while one side or rear access is required for installation and fastening of customer connections.

The Mission Critical (MC) Series provides redundant operation using two sources feeding one common group of output distribution devices within one unit.

By intergrating a Cyberex SuperSwitch4 Digital Static Transfer Switch (DSTS) and a Cyberex Power Distribution Unit (PDU), the MC series provides the highest level of configurability for diverse equipment loads and maximum growth. Coupled with advanced circuit management options and communications, the MC Series is the key to design element for ensuring maximum uptime for your facility.

The MC11 Series is a Cyberex SuperSwitch4 Digital Static Transfer Switch (DSTS) at the input of a transformer that feeds output distribution devices which may include sub-feed breakers and/or panelboards.

These integrated packages offer a single, easy-to-install, factory-tested unit that avoids expensive inter-cabinet wiring all within a compact footprint. This compact footprint maximizes valuable floor space and reduces power cabling costs. A multitude of available distribution features and comprehensive circuit management with advanced communications provides the ultimate in design flexibility and reliability.

Raritan's Intelligent Hybrid Rack Mount Transfer Switch system is the first in the world to offer both electromechanical relays and silicon-controlled rectifiers (SCRs) to overcome the limitations of a traditional automatic transfer switch (ATS). It provides load transfer times that are comparable to that of a static transfer switch (STS), more energy efficiently, and at a far more accessible price point. It is also the first in the world to offer inlet, outlet, and branch circuit level power metering; and outlet-level switching for better remote power control.

Raritan's rack transfer switch offers:

• Current sampling at 4,800 times per second for load transfers within 4 to 8ms.
• Oversized relays, rated at 48A, and SCRs, rated at 70A, even though the transfer switches are intended for 16A and 32A loads.
• Relay contact air gap of 3.3mm vs. the 0.6mm gap used in most transfer switch relays on the market to prevent electric arcing.
• Two single throw relays instead of one double throw relay (a single point of failure) to support reliable out-of-phase transfers.
• Inlet, outlet, and branch circuit level metering.
• Remote outlet switching.
