Schneider Electric ATV312HU11N4 Variable Frequency Drive

Schneider Electric ATV312HU11N4 is a 1.1 kW Altivar 312 variable-frequency drive designed to control 3-phase asynchronous motors from a 380–500 VAC supply. Packaged with a heatsink, it delivers a 3.2 kVA apparent power rating and up to 4.9 A at 380 V (3.7 A at 500 V), with Isc of 5 kA and 48 W dissipation at nominal load. It supports sensorless flux vector control with PWM and a factory-set constant torque profile, providing smooth speed ramping across a 1–50 Hz range. The unit includes an integrated EMC filter and is designed for industrial motor control with a 3‑phase input. Sited in the Altivar 312 family, it drives 3‑phase asynchronous motors in applications such as pumps, fans, and conveyors, where a compact, integrated heatsink drive is advantageous.
