The Schneider ATV9B0C45T4 is a modular Altivar Process ATV900 drive rated 650 hp at 480 V normal duty and 550 hp heavy duty, with line current 626 A normal duty and 533 A heavy duty. Apparent power hits 520 kVA at 480 V normal duty, 443 kVA heavy duty. Supply rails are split: 24 V DC (19…30 V) for digital inputs, a 10.5 V DC reference for a 1–10 kΩ potentiometer, and a separate 24 V DC (21…27 V) rail for digital inputs and STO. Integrated EMC filter meets IEC 61800-3 category C3 for 300 m cable runs.
Two duty curves are on record: normal duty at 626 A line current (650 hp), heavy duty at 533 A (550 hp). The regenerative mode ratings are slightly lower — 543.4 A normal duty, 457.4 A heavy duty. Pick the heavy-duty column if the load profile includes sustained overload or high starting torque; normal duty covers constant-torque variable-speed applications.
Safety and compliance
The drive carries CE marking and complies with IEC 61800-3, IEC 61800-5-1, IEC 61000-3-12, IEC 60721-3, UL 61800-5-1, and pollution degree 2. EMC filter is integrated to category C3.
