Schneider Electric ATV312HU15N4 Variable Frequency Drive

Schneider Electric ATV312HU15N4 AC Variable Frequency Drive is a 1.5 kW (2 HP) motor controller in the Altivar 312 family, designed to regulate speed and torque of three-phase motors in conveyors, pumps, fans, and light industrial machinery where precise control is required. It accepts 380–500 VAC, three-phase input and delivers an output frequency range of 0–500 Hz with an output current of about 4.1–6.4 A and an apparent power of roughly 4.2 kVA, with overload capability at 150% for 60 seconds. Control methods include V/F control and sensorless vector control, and the drive features built-in Modbus and CANopen communications, an integrated EMC filter, and a panel-mount IP20 enclosure. Maintenance teams and system integrators commonly use ATV312HU15N4 for replacement, retrofit, and system upgrades to improve efficiency and performance in industrial automation environments.
