To offer greater consistency and efficiency, GE's Critical Power business has recently unveiled a new line of GE Zenith STS-3 Series three-phase static transfer switches and GE Zenith STS-1 Series single-phase static transfer switches, useful for critical infrastructure applications.
The STS-3 Series three-phase units are best suited in the area where centralized power source redundancy is required, such as a data center, telecommunications, financial or industrial critical infrastructure usage. On the other hand, the new GE Zenith STS-1 Series static transfer switches offer a single-phase solution for customers that want to deploy the switches in a rack-mount form factor.
The GE Zenith STS-3 Series static transfer switches offer critical loads with two sources of electrical power to select. Thanks to the technology, the new STS-3 Series enables out-of-phase transfers between power sources without undue inrush current on the electrical system, when power distribution unit transformers are employed on the load side of the static transfer switch.
With a sense and transfer time of less than 4ms, the STS-3 represents the highest performance power switching solution available, according to the company.
The new GE static transfer switches are currently available in a wide range of ampere ratings and are part of a complete GE critical power distribution solution. These switches include UPS systems upstream of the static transfer switch units and power distribution units, and/or power overhead busway systems downstream of the static transfer switch units.
"We're delivering a full line of static transfer switch solutions to meet a wide range of customer requirements in the data center and other critical process markets," said Ray Prince, Americas UPS segment leader at GE's Critical Power business.
The pricing for the new GE Zenith STS-3 Series starts at $10,000 and pricing for the GE Zenith STS-1 Series starts at $1,700, depending on the amp rating.
