What this drive is built for
The Schneider Electric ATV1200A29604242 is an Altivar 1200 medium-voltage drive rated for 2475 kW motor power with an apparent power of 2960 kVA, fed from a 2970...3630 V supply via a 24-pulse diode rectifier bridge. It drives both synchronous and asynchronous motors across a 20...100 % speed range, with overload capability of 1.2 In for 60 s (standard) or 1.5 In for 60 s (high overload).
Physical footprint and enclosure
This is a floor-standing enclosure with separate air flows for power and control sections — standard efficiency measures 5170 mm wide × 2670 mm high × 1600 mm deep; high efficiency is 5470 mm wide × 2670 mm high × 1700 mm deep. Forced convection cooling moves 26,400 m³/h of air, and the drive is rated for vertical operation within ±10 degrees.
Input harmonics and power quality
The 24-pulse input rectifier reduces line current harmonics without an external filter — line current is 410 A at the rated load, and the integrated EMC filter meets EN/IEC 61800-3 conducted emission limits. Prospective line short-circuit current withstand is 31.5 kA for 150 ms, and dielectric strength between earth and power terminals is 20 kV AC.
Control power and I/O
Control electronics require an external 220 V AC, 3 kVA supply; the cooling fan runs on 380 V AC internal supply, with optional external supply for both. The drive provides 4 software-configurable analog inputs (0...20 mA / 4...20 mA, 250 Ω impedance), 2 analog outputs (same range), and 6 discrete inputs (expandable to 10).
CE marked, pollution degree 2 per EN/IEC 61800-5-1, overvoltage category II. Operating altitude is 1000...2000 m with 0.6 % current derating per 100 m above 1000 m. Relative humidity range is 0...90 % (0...95 % optional), and vibration resistance is 4.9 m/s² at 10...50 Hz. Noise level is 80 dB.
