Schneider ATV312HD11N4 Variable Frequency Drive

Overview

The Schneider Electric ATV312HD11N4 is an 11 kW variable frequency drive (VFD) from the Altivar 312 series. It controls three-phase asynchronous motors at 380–500 V. This drive provides precise speed and torque management while improving energy efficiency. It supports robust industrial performance and reduces mechanical stress on connected machinery. The ATV312HD11N4 is ideal for pumps, fans, conveyors, and general-purpose machines. Its compact design allows flexible wall or panel mounting. Integrated safety and communication features enhance reliability and system integration.
