Altivar 212 drive, 18.5 kW at 480 V
The ATV212HD18N4 is a variable-speed drive from the Schneider Altivar 212 range, rated for 18.5 kW motor power on a 3-phase 480 V supply. Line current draws 27.8 A at 480 V (34.8 A at 380 V), so the upstream protection and cable sizing should be based on the higher figure if the installation runs at 380 V.
Integrated C2 EMC filter and compliance suite
This drive ships with a built-in class C2 EMC filter, which covers most industrial environments without an external filter. The standards list includes IEC 61800-3 categories C1 through C3, EN 55011 Class A Group 1, and IEC 61800-5-1 — meaning it meets conducted and radiated emission limits for first-environment (residential) and second-environment (industrial) installations, depending on cable length and installation practice. CE marking is on the nameplate.
Protection and monitoring coverage
The drive's protection suite covers overheating of the power stage, short-circuit between motor phases, earth faults, input phase loss, DC bus overvoltage and undervoltage, motor thermal protection, and motor phase break detection. It also accepts PTC probes for direct motor winding temperature monitoring. The adjustable PI regulator handles closed-loop process control for fans, pumps, and conveyors without an external controller.
Communication and control interface
Standard communication is via a 2-wire RS-485 physical interface using Modbus RTU protocol at 9600 or 19200 bps, 8-bit data, configurable parity. An RJ45 connector provides the bus connection. An optional LonWorks communication card is available for building-automation networks. The analogue inputs are switch-configurable between voltage (0–10 V DC) and current (0–20 mA), with 10-bit resolution.
Mounting and environmental limits
The drive measures 330 mm high, 245 mm wide, and 190 mm deep, with a vertical mounting tolerance of ±10°. It requires 100 mm clearance above and below for airflow — the fan moves 214 m³/h. Full rated current is available up to 1000 m altitude; above that, derate 1 % per 100 m up to 3000 m. For corner-grounded distribution networks, limit altitude to 2000 m. Pollution degree 2 per IEC 61800-5-1 applies.
