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.
