The new GE Zenith STS-3 static transfer switches provide power source redundancy in uninterruptible power supply (UPS) system architectures to increase product mean time between failure between the power source and the critical load, using features such as internal triple redundancy of control power and logic, GE says.
Customers who deploy two independent UPS systems in their critical power infrastructure with downstream GE static transfer switches can enhance system reliability by about 30 percent as compared to paralleled UPS system designs that do not deploy static transfer switch devices, according to GE.
This architecture also provides added flexibility because one UPS can be isolated for repair or maintenance while the other protects critical loads via a manually initiated static transfer switch source transfer, GE says.
The new GE Zenith STS-1 Series static transfer switches provide a single-phase solution for customers who want to deploy the switches in a rack-mount form factor to provide dual input source capabilities to rack-mounted single-cord IT servers or other non-IT critical process equipment.
GE Zenith STS-3 Series three-phase units are aimed at data center, telecommunications, financial and industrial critical infrastructure customers seeking centralized power source redundancy, while the GE Zenith STS-1 single-phase static transfer switches are for point-of-use power source redundancy at the localized rack level, GE says.
