The Vertiv™ Geist™ Rack Transfer Switch (RTS) delivers redundant power to single corded devices. Two independent power inputs enables users to connect to a primary and secondary power source. The Vertiv™ Geist™ Rack Transfer Switch automatically detects the loss of power and switches the power load to the alternative power source in less than 4-8 milliseconds without the need for human intervention. This ensures equipment remains powered until the primary power source returns providing ultimate mission-critical power reliability. The Rack Transfer Switch is an open transition switch utilizing a break-before-make process for transferring between the primary and secondary power source. This method of switching does not require phase synchronization between the two power feeds making it suitable for use in both data center and edge locations. It also includes enhanced redundant switches and fail-safe fused thermistors to mitigate current surge during transfers ensuring critical equipment is protected during fail-over.
