Multiple outputs enable a cost-effective power supply for rack-mounted devices. Various inputs and outputs for distributing 120 V, 208 V, or 230 V mains voltage across multiple connections provide users with the flexibility to adapt to different power requirements. The devices support up to 14.4 kW of power per branch whip. Multiple devices can be powered through a branch whip; this is a particularly convenient method of supplying power to rack devices. By using a branch whip with standard connections, the time and cost involved in installation are reduced. Models for horizontal, vertical, and tool-less mounting provide power connections exactly where they are most needed in the racks, in close proximity to the devices.
