Schneider Electric ATV312H075N4 AC Variable Speed Drive

The Schneider Electric ATV312H075N4 Altivar 312 AC variable speed drive provides precise speed control for small to mid-size asynchronous motors, rated at 0.75 kW (1 hp) with a 2.4 kVA output and a 41 W draw at rated load. It accepts a 380–500 V three-phase supply, with some regional listings extending to 323–550 V, making it compatible with common industrial mains in Europe and beyond. This drive is commonly used to control motors in pumps, fans, conveyors, and other automated equipment requiring variable torque and speed, and it is part of the Altivar 312 family that emphasizes straightforward parameterization for motor control tasks. Integrated communications include CANopen and Modbus, enabling easy connection to PLCs and SCADA systems, while the enclosure measures about 107 mm wide, 143 mm tall, and 152 mm deep for compact installation. Schneider lists ATV312H075N4 with a contemporary replacement in many markets: the ATV320U07N4C, a 0.75 kW, 380–500 V three-phase option, useful for planning replacements or upgrades.
