The Schneider ATV212HU55N4LCD is a 5.5 kW (7.5 hp) variable speed drive from the Altivar 212 series, designed for three-phase asynchronous motors on 380...480 V supplies. It draws 10.9 A at 380 V and 8.6 A at 480 V line current, with an apparent power rating of 9.1 kVA at 380 V. The integrated Class C2 EMC filter covers most industrial installations without an external filter — saves a DIN-rail slot and a wiring step. Communication is over a 2-wire RS 485 Modbus RTU link at 9600 or 19200 bps, addressing up to 247 nodes, which fits into a standard control network without a gateway. The drive includes an adjustable PI regulator for closed-loop process control (pressure, flow, level) without a separate controller. Protection covers motor and drive sides: thermal overload, short-circuit between motor phases, input phase loss, DC bus overvoltage/undervoltage, and PTC probe input for motor overtemperature.
Footprint is 184 mm high by 142 mm wide by 150 mm deep, with a heat sink on the back. Mount vertical within ±10° for proper airflow — the fan moves 74 m³/h. Leave clearance above and below for convection; the heat sink dissipates drive losses without derating up to 1000 m altitude. Above that, derate 1 % per 100 m, and for corner-grounded distribution networks limit to 2000 m. The IP20 enclosure is panel-mount only, not for washdown or outdoor use without a separate cabinet.
