Schneider Electric ATV312H075N4 AC Drive Inverter

The Schneider Electric ATV312H075N4 AC Drive Inverter is a 1 HP variable frequency drive designed to precisely control speed and torque of three-phase motors in industrial automation. Part of the Altivar 312 family, it delivers 0.75 kW (1 HP) with input 380–500 VAC, 3‑phase, and a 3‑phase output up to the input voltage, supporting an output frequency range of 0–500 Hz and a continuous output current of about 2.3 A. Control methods include V/F and sensorless vector control, with built-in Modbus and CANopen communication. The drive provides 6 digital inputs and multiple analog inputs/outputs for flexible integration, and it offers overload capability up to 150% for 60 seconds, along with protection features such as overload, overvoltage, undervoltage, short-circuit, and phase loss. Mounting is panel mount (IP20). Common applications include conveyors, pumps, fans, and light industrial machinery for precise motor speed and torque control; in broader use it supports manufacturing systems, material handling equipment, HVAC, and packaging machinery to optimize energy use and process control.
