Schneider Electric ATV312H055N4 Variable Speed Drive

Schneider Electric’s ATV312H055N4 Altivar 312 variable speed drive delivers 0.55 kW (0.75 HP) motor control for three‑phase asynchronous motors powered from 380–500 VAC, with a compact, heat‑sink‑equipped enclosure and an IP20 rating for indoor use. It provides 1.8 kVA apparent power and a rated input current of 1.9 A (2.8 A at 380 V, 2.2 A at 500 V), along with a 37 W heat dissipation figure, and a speed range of 1–50 Hz using sensorless flux vector PWM with a factory constant torque setting. Key integrated features include a C2 EMC filter, and built‑in CANopen and Modbus communications, making it suitable for automation panels and general‑purpose machine control. The drive weighs about 4.7 lb (≈2.15 kg) and operates over a temperature range of -10°C to 50°C, supporting UL Listed, CSA Certified, and CE Marked approvals. Assembly style with a heat sink, 3‑phase input and 3‑phase output, this Altivar 312 model is intended for precise, energy‑efficient control of small motors in industrial applications.
