The Schneider Electric ATV950U55N4 is a 5.5 kW class variable speed drive from the Altivar Process 950 series, designed for heavy-duty industrial process control where reliability, energy efficiency, and advanced system connectivity are essential.
It is widely used in pumps, conveyors, crushers, mixers, extruders, and wastewater treatment systems, especially in environments where continuous operation and stable torque control are required under variable load conditions.
As part of Schneider Electric’s process automation drive platform, it integrates embedded intelligence for energy monitoring, predictive diagnostics, and industrial communication, enabling seamless integration into modern digital infrastructure such as SCADA and IIoT systems.
Its IP55-rated wall-mounted enclosure allows decentralized installation close to the machine, reducing cabinet complexity and improving installation flexibility in harsh environments.
