Schneider Electric ATV312HU40N4 Variable Frequency Drive

The Schneider Electric ATV312HU40N4 AC Variable Frequency Drive is a 5 HP motor drive designed to regulate speed and torque for three-phase motors in industrial automation. It serves conveyors, pumps, fans, compressors, and packaging machinery that require precise variable-speed control, with the capability to improve energy efficiency and process stability in manufacturing and material handling environments. Key specs include 380–500 VAC three-phase input, 9.2 kVA apparent power, and an output frequency range of 0–500 Hz with an approximate 9.5 A output current. It supports Sensorless Vector control and V/F control, with overload capability up to 150% for 60 seconds, and communications via Modbus and CANopen. Protection features cover overcurrent, overvoltage, and thermal protection, and the unit is panel-mounted with a heat sink, featuring an IP20 enclosure rating (typical) and a weight of about 3.1 kg. Common replacements for compatibility include Schneider Electric ATV320U40N4C, reflecting its place within Schneider Electric’s family of motor drives. This drive is widely deployed in manufacturing plants, processing facilities, and HVAC or material handling systems to enable smoother motor performance and tighter process control.
