You're looking at a 380-480 V three-phase drive in an IP55 wall-mount enclosure, so it's ready for direct installation in washdown or dusty environments without an extra cabinet. The compliance package covers UL 508C, IEC 61800-3, IEC 61800-5-1, IEC 61000-3-12, IEC 60721-3, IEC 61508, and IEC 13849-1. EMC immunity is tested to level 3/4 on key transients, which simplifies approvals for process lines or marine panels. The 90 kW normal duty covers variable-torque loads like pumps and fans; drop to 75 kW heavy duty for constant-torque applications such as conveyors or extruders. The continuous output current is 173 A at 2.5 kHz switching frequency — higher switching derates that number. The integrated EMC filter covers conducted emissions; an optional EMC plate is available. The load break switch and braking chopper are built in. Mount it vertical ±10°, wall-mount style. Line-side screw terminals accept 95 mm², motor side up to 120 mm². Control terminals are 0.5-1.5 mm² screw. Slots A/B/C accept communication modules (Profibus, PROFINET, EtherNet/IP, EtherCAT, CANopen) or I/O extensions. Encoder feedback options for slot B include 5/12 V digital, analog, or resolver. IP55 with chemical resistance class 3C3 and dust class 3S3 per IEC 60721-3-3. Rated for 15 gn shock (11 ms) and 1 g vibration (13-200 Hz). The operating altitude window is up to 4800 m with 1% current derating per 100 m above 1000 m.","metaTitle":"ATV950D90N4E Altivar Process ATV900 VSD, 90 kW, 173 A, IP55","metaDescription":"Active production Altivar Process ATV900 VSD, 90 kW normal duty, 380-480 V, 173 A output, IP55, with braking chopper.
