Micro Hydraulic AC Power Pack
What is a Micro Hydraulic AC Power Pack?
A Micro Hydraulic AC Power Pack is a compact, self-contained hydraulic system designed to generate high-pressure fluid power using an AC electric motor. It is typically used in applications where space is limited, but precise and powerful hydraulic actuation is required.
Unlike full-sized hydraulic units, micro packs are smaller (often under 1 HP), efficient, and ideal for light- to medium-duty operations like lifting, clamping, or actuating mechanisms in machines, tools, medical devices, and mobile equipment.
