Medium voltage drive for 2.6 MW asynchronous motors
The ATV1200A31301010 is a Schneider Electric Altivar 1200 medium voltage variable speed drive rated for 2617 kW motor power at 3130 kVA apparent power, supplied from a 2970...3630 V three-phase line through a 48-pulse diode rectifier bridge. This is a floor-standing enclosure with separate air flows for the power cells and transformer, measuring 1500 mm deep by 6870 mm wide by 2670 mm high in its standard-efficiency configuration. It is designed for asynchronous (induction) motors and includes an integrated EMC filter, ground fault protection, and forced convection cooling.
Overload profile and short-circuit withstand
The drive handles 1.2× rated current for 60 seconds and 1.5× for 3 seconds under standard overload; a high-overload profile allows 1.5× for 60 seconds and 1.85× for 3 seconds. Prospective line short-circuit current is rated at 31.5 kA for 150 ms, and the dielectric strength between earth and power terminals is 28 kV AC. Operating altitude is 1000...2000 m with a 0.6 % current derating per 100 m above 1000 m; pollution degree 2 per EN/IEC 61800-5-1 and overvoltage category II apply.
Control supply and I/O complement
Control power requires an external 220 V AC supply at 3 kVA; the cooling fan draws from an internal 380 V AC supply. An optional external 220 V AC/DC control supply is available. The drive provides 4 software-configurable analog inputs (0...20 mA / 4...20 mA, 24 V max, 250 Ω impedance) and 1 analog output of the same type, plus 6 discrete inputs (10 optional). Electrical isolation is maintained between power and control circuits. The main power connection uses bar-type screw terminals M10, accepting up to 6 × 40 mm² cable per phase, entry from bottom or top.
Standards compliance and environmental limits
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. Relative humidity range is 0...90 % standard, 0...95 % optional. Vibration resistance is 4.9 m/s² at 10...50 Hz. Operating position is vertical ±10 degrees. Noise level is 80 dB. The enclosure is grey (RAL 7032). The product composition includes 2 plinths, a phase-shifting transformer, medium voltage arrestors, cooling fans, a human machine interface, and 24 power cells.
