Schneider Electric ATV12H055M2 Variable Speed Drive

Schneider Electric ATV12H055M2 Altivar 12 variable speed drive is a compact, 0.55 kW (0.75 HP) inverter designed to control a single‑phase 200–240 VAC motor in cabinet installations, with an integrated heat sink and an IP20 enclosure. It accepts 200–240 V mains (50/60 Hz) and delivers up to 3.5 A continuous output current, with a configurable output frequency range of 0.5–400 Hz and a motor speed range of 1–20. The unit belongs to the Altivar 12 family and is suitable for small conveyors, pumps, fans, and machine tools where precise speed control is required. Its I/O includes 4 digital inputs, 2 digital outputs, 1 analogue input, 1 analogue output, and 1 relay output, while communication is provided via Modbus over a 2‑wire RS‑485 port with an RJ45 connector. For protection, the drive includes safeguards such as line voltage over/under‑voltage, overcurrent between output phases and earth, overheating, and motor protection based on I²t calculations. Its compact footprint measures 72 mm in width, 143 mm in height, and 131.2 mm in depth, and it weighs about 0.8 kg, making it well suited to panel installations with limited space.
