The 36-pulse diode rectifier front end cleans up line harmonics well below IEEE 519 thresholds without external filtering. Supply voltage range is 2970...3630 V. Output voltage follows the supply, so the motor sees the full line voltage minus rectifier drop. The 36-pulse topology means the transformer feeding it needs 6 secondary windings phase-shifted 10 degrees apart. ## Overload duty and thermal management Standard overload profile: 1.2× In for 60 s, 1.5× In for 3 s. High overload profile steps up to 1.5× In for 60 s and 1.85× In for 3 s. The high overload setting is the one to budget for if the driven load has breakaway torque demands — a crusher or centrifuge, not a centrifugal pump. Forced convection cooling moves 13,200 m³/h in the standard-efficiency build, 19,800 m³/h in the high-efficiency variant. That volume of air needs ducting out of the room — the drive rejects heat at the transformer and cell level, not through a backplane heat sink. Acoustic noise hits 80 dB, so plan for ear protection in the vicinity during commissioning. ## Physical footprint and site prep Floor-standing enclosure with separate air flows. Standard-efficiency footprint: 3060 mm wide × 1400 mm deep × 2520 mm high. High-efficiency build: 3360 mm wide × 1500 mm deep × 2670 mm high. The width difference matters for cable entry planning — the high-efficiency cabinet has more cell bays and wider buswork. Electrical connection via M10 screw-type bar terminals, clamping capacity 6 × 40 mm² per phase. Entry from top or bottom. The 31.5 kA prospective short-circuit current for 150 ms means the upstream protection must coordinate — a 36-pulse transformer typically has higher impedance than a 6-pulse unit, so the fault let-through is lower, but the SCCR rating of the drive itself needs to match the installation. ## System composition and control interface The drive ships as a complete assembly: 2 plinths, phase-shifting transformer, medium-voltage arrestors, cooling fans, HMI, and 18 power cells. The 18 cells means 6 cells per phase in a 36-pulse configuration — each cell is a low-voltage inverter stage fed from its own transformer secondary. If a cell faults, the drive can typically continue at reduced voltage with the remaining cells. Control interface: 4 software-configurable analogue inputs (0...20 mA / 4...20 mA, 250 Ohm impedance), 1 analogue output, 6 discrete inputs standard with optional expansion to 10. The control supply is 220 V AC at 3 kVA — this powers the control electronics independently of the main power bus, so the HMI and I/O stay live even with the main breaker open. ## Compliance and standards coverage CE marked. Standards compliance includes EN/IEC 60204-11 (safety of machinery), EN/IEC 61800-3 (EMC for drive systems), EN/IEC 61800-4 (voltage disturbances), and EN/IEC 61800-5-1 (electrical safety). Pollution degree 2 per EN/IEC 61800-5-1 — the enclosure is rated for a clean industrial environment, not cement dust or foundry grit. Dielectric strength tested at 20 kV AC between earth and power terminals. Electrical isolation between power and control means the 24 V I/O loop is galvanically separated from the 3 kV bus — no ground-loop coupling through the control cable shield.","metaTitle":"Schneider ATV1200A9406666 Altivar 1200 VFD, 940 kVA, 786 kW","metaDescription":"Schneider Electric ATV1200A9406666 medium-voltage VFD, 940 kVA apparent power, 786 kW motor rating, 36-pulse input, CE marked.
