DC hydraulic power units (HPUs) are battery-operated and used to power tail-gate lifts, agricultural and marine equipment, dump trailers, and other portable hydraulic tools. They are smaller and more compact than AC power units and can be installed in hard-to-reach areas. DC hydraulic power units can be operated where access to a reliable electrical power source is limited or unavailable. They provide higher amounts of force than traditional electrical and mechanical systems, allowing hydraulic power units to lift and move heavier loads in a smaller footprint. DC hydraulic power units also provide precise movement and speed control over a wide range of speeds and load weights.
