18.5 kW at 480 V — motor power and line-side draw
The ATV212HD18N4LCD: This Altivar 212 drive is rated for 18.5 kW (25 hp) output to an asynchronous motor at 480 V supply. Line current at that voltage is 27.8 A; at 380 V it draws 34.8 A. That 27.8 A figure governs the upstream breaker and cable sizing — the drive itself handles the lower-voltage current rise without derating the output stage.
Integrated C2 EMC filter — no external box needed
The ATV212HD18N4LCD ships with a Class C2 EMC filter built in. For a panel builder, that means the drive meets conducted emission limits for industrial environments (second environment / C2 per IEC 61800-3) without an add-on filter module. The standards list covers both C1 and C2 in environments 1 and 2, plus UL Type 1 — so it qualifies for North American and European installs with the same hardware.
Protection suite — 12 monitored faults
The drive monitors overcurrent, short-circuit between motor phases, earth faults on the output, DC bus overvoltage and undervoltage, input phase loss, motor thermal overload, PTC probe input, and control circuit break. That covers the commissioning checklist for most pump, fan, and conveyor starts — no external motor relay needed for the thermal protection leg.
Modbus RTU on RS-485 — standard comms, no option card
The drive has a 2-wire RS-485 physical interface with Modbus RTU protocol, configurable 9600 or 19200 bps, 8 data bits, 1 stop, parity configurable. Addressing range is 1–247. For a controls integrator wiring a multi-drive line, this is the native fieldbus — no extra communication card required for Modbus. An optional LonWorks card is listed for building automation tie-in.
