Medium-voltage drive for 660 kW motors — 30-pulse rectifier, floor-standing
The ATV1200A7906060 is a Schneider Electric Altivar 1200 medium-voltage AC drive rated for 660 kW motor power with 790 kVA apparent power, supplied from a 2970–3630 V three-phase line via a 30-pulse diode rectifier bridge. This is not a 480 V drive — it sits in the medium-voltage class, designed for large induction and synchronous motors in high-power applications like pumps, compressors, fans, and conveyors in heavy industry. The 30-pulse input topology is the key differentiator here — it cancels the 5th, 7th, 11th, 13th, 17th, and 19th harmonics at the input without a separate active filter. For a site with IEEE 519 compliance requirements, this drive meets the harmonic limits at the point of common coupling without additional line reactors or multi-pulse transformers beyond the integrated phase-shifting transformer.
Physical footprint and site planning — 1400 mm deep, 2860 mm wide
This drive ships in a floor-standing enclosure with separate air flows for the power cells and control section. The standard-efficiency variant measures 1400 mm deep by 2860 mm wide by 2590 mm high; the high-efficiency version adds depth to 1500 mm, width to 3460 mm, and height to 2740 mm. Plan for a dedicated equipment room with overhead clearance for the lifting beam — this is not a wall-mount drive. Forced convection cooling moves 16600 m³/h (standard efficiency) or 23200 m³/h (high efficiency) of air. The noise level is 80 dB — hearing protection zones around the enclosure are expected. The enclosure colour is grey RAL 7032.
Overload capability and duty selection
Two overload profiles are available: standard overload (1.2 × In for 60 s, 1.5 × In for 3 s) and high overload (1.5 × In for 60 s, 1.85 × In for 3 s). The standard profile suits variable-torque loads like centrifugal pumps and fans where the overload duration is short; the high-overload profile is for constant-torque loads like conveyors or extruders that need sustained torque during start-up or jam conditions. The drive includes ground fault protection on the output and an integrated EMC filter. Dielectric strength is 20 kV AC between earth and power terminals — essential for medium-voltage isolation integrity.
Active production — current lifecycle status
Compliance documentation includes CE marking and conformity to EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1. Pollution degree 2 per IEC 61800-5-1, overvoltage category II.
