24VDC Power Hub 3500 Operator Manual
Power Hub Introduction
The primary function of the DC Power Hub is to serve as a singular collection, management and
distribution tool for DC power in a Hybrid Power System (HPS).
The Hub is designed specifically for operation between energy-storage batteries and DC generation
sources, including photovoltaic (PV) arrays, wind generators, fuel cells, small hydro generation,
vehicular power, and more. It regulates the incoming power, making it compatible for a connected
battery, loads, or distribution devices such as inverters.
Power Hubs play a critical role in applications where any combination of the following is necessary:
• Renewable power generation is required to support a battery
• Reducing generator run-time in a hybrid system is critical
• Less reliance on grid-utility power is desirable
• DC power management and distribution is required for a battery platform
It is a modular component of the HPS architecture, and its flexible design allows use with other
technologies that collectively meet specific mission requirements.
All Power Hubs are “Plug & Play”-compatible with the Inter-Connect circuit and are modular and
scalable. Their design allows multiple Power Hubs to be used in a single application where power
management requirements exceed the ability of a single Hub, or when multiple DC loads are
required to meet the demand.
The Power Hub includes one DC Inter-Connect Cable for connection to an HPS.
