Schneider Electric ATV312H075N4 Variable Frequency Drive

Schneider Electric's ATV312H075N4 is a 0.75 kW Altivar 312 variable-frequency drive (VFD) designed to run three-phase asynchronous motors from a 380–500 V supply, with a 50–60 Hz input range and a compact heat-sink assembly. It provides 2.4 kVA of apparent power, draws 3.6 A at 380 V or 2.7 A at 500 V, and dissipates about 41 W under nominal load, with an integrated EMC filter to suppress conducted emissions and a heat-sink package. The drive uses sensorless flux vector control with PWM, is factory-set to a constant-torque profile, and supports a speed range of 1–50, enabling precise speed control for small to medium automation tasks. Schneider Electric discontinued ATV312H075N4 on January 26, 2021, and recommends the ATV320 family as the replacement, for example ATV320U07N4C, which maintains the 0.75 kW rating and 380–500 V three-phase operation.
