Medium-voltage drive for large asynchronous and synchronous motors
The Schneider Electric ATV1200A22906060 is a medium-voltage variable frequency drive from the Altivar 1200 family, rated for 1914 kW motor power at 2290 kVA apparent power. It is designed to control both asynchronous and synchronous motors in high-power applications such as pumps, fans, compressors, and conveyors in heavy industry. The drive accepts a supply voltage of 2970–3630 V AC and draws 220 A line current through a 30-pulse diode rectifier bridge, which inherently reduces line-side harmonics to meet IEEE 519 without external filters.
Architecture and overload capability
The ATV1200A22906060 uses a modular cell-based topology: 15 power cells fed by a phase-shifting transformer, with two plinths, medium-voltage arrestors, cooling fans, and a human-machine interface. This architecture allows ride-through of individual cell faults without tripping the drive. Overload capability is configurable: standard overload allows 1.2× In for 60 s and 1.5× In for 3 s; high overload allows 1.5× In for 60 s and 1.85× In for 3 s. The 1.2× In standard overload profile suits variable-torque loads like centrifugal pumps; the 1.5× high overload profile matches constant-torque loads such as conveyors or extruders.
Physical footprint and installation constraints
The drive is supplied in a floor-standing enclosure with separate air flows for the power section and control electronics. Dimensions vary by efficiency variant: standard efficiency measures 4660 mm wide × 1600 mm deep × 2670 mm high; high efficiency is 4960 mm wide × 1700 mm deep × 2670 mm high.
The drive carries CE marking and complies with EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3 (EMC), EN/IEC 61800-4, and EN/IEC 61800-5-1. Pollution degree 2 per EN/IEC 61800-5-1 and overvoltage category II apply to the control circuits. Dielectric strength between earth and power terminals is 20 kV AC. The integrated EMC filter covers conducted emissions for the first environment (unrestricted distribution) per EN/IEC 61800-3. Operating altitude is 1000–2000 m with a current derating of 0.6 % per 100 m above 1000 m. Ambient relative humidity range is 0–90 % (0–95 % optional). The drive is rated for vibration resistance of 4.9 m/s² at 10–50 Hz.
