Medium-voltage drive for large asynchronous and synchronous motors
The ATV1200A19706363 is a Schneider Electric Altivar 1200 series AC drive rated for 1371 kW motor power with a supply voltage range of 2970 to 3630 V. It uses a 36-pulse diode rectifier bridge input topology, which reduces line-side harmonics without requiring external filters for most grid codes. The drive is designed for both asynchronous and synchronous motors, making it suitable for large pumps, fans, compressors, and conveyors in heavy industrial applications.
Physical footprint and site integration
This drive ships as a floor-standing enclosure with separate air flows for power and control sections. Standard efficiency dimensions are 3960 mm wide, 2740 mm high, and 1500 mm deep; the high-efficiency variant is 4260 mm wide and 1600 mm deep. Forced convection cooling requires 29900 m³/h (standard efficiency) or 33200 m³/h (high efficiency) of cooling air — plan the room HVAC capacity accordingly. Acoustic noise at full load is 80 dB, which may require hearing protection in the vicinity or enclosure treatment.
Electrical ratings and protection
Apparent power rating is 1640 kVA with a line current of 150 A at the nominal supply voltage. Output voltage is limited to the supply voltage level. Overload capability: 1.2× rated current for 60 seconds (standard overload), 1.5× for 3 seconds (standard), and 1.5× for 60 seconds (high overload), 1.85× for 3 seconds (high overload). This allows sizing for either normal or heavy-duty starting profiles. Prospective line short-circuit withstand is 31.5 kA for 150 ms. Dielectric strength between power terminals and earth is 20 kV AC. Ground fault protection is integrated into the drive.
Control interface and auxiliary supplies
The drive includes 4 software-configurable analog inputs (0-20 mA / 4-20 mA, 250 Ohm impedance) and 1 analog output of the same type. Discrete inputs are 6 standard, expandable to 10. Control electronics require an external 220 V AC supply at 3 kVA. The cooling fan has its own internal 380 V AC supply, with an optional external 380 V AC fan supply available. Power connection uses M10 screw-type bar terminals accepting up to 6 × 40 mm² cable, with entry from bottom or top.
Standards, environment, and compliance
CE marked and designed 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, overvoltage category II per EN/IEC 61800-5-1. Operating altitude is 1000 to 2000 m with current derating of 0.6% per 100 m above 1000 m. Relative humidity range is 0-90% (0-95% optional). Installation must be vertical within ±10 degrees. Vibration resistance is 4.9 m/s² at 10-50 Hz. An integrated EMC filter is included.
