18.5 kW at 480 V — motor power and line current
The ATV212WD18N4 is a 3-phase AC drive rated for 18.5 kW motor power at 480 V, drawing 27.8 A line current at that voltage (34.9 A at 380 V). This places it squarely in the mid-power segment of the Altivar 212 family, sized for standard asynchronous motors in pump, fan, and compressor duty.
Integrated C2 EMC filter — compliance without external add-ons
A Class C2 EMC filter is built in, covering conducted emissions for industrial environments per IEC 61800-3. This eliminates the need for a separate external filter in most installations, simplifying panel layout and reducing component count. The drive also carries CE marking and complies with EN 55011 Class A Group 1 and multiple IEC 61800-3 environment categories (C1, C2, C3).
Protection coverage and control features
The drive includes thermal protection for both the power stage and the motor, short-circuit protection between motor phases, overcurrent between output phases and earth, overvoltage/undervoltage on the DC bus, input phase loss detection, and motor phase break monitoring. An adjustable PI regulator is built in for closed-loop process control without an external controller.
