1045 kW medium-voltage drive with 48-pulse rectifier
The Schneider Electric ATV1200A12501010 is an Altivar 1200 series AC drive rated for 1045 kW motor power at 1250 kVA apparent power, designed for medium-voltage applications with a 48-pulse diode rectifier bridge input. Supply voltage limits span 2970...3630 V, making it a medium-voltage drive suited for large induction motor loads like pumps, conveyors, and compressors in heavy industry.
Overload profile and cooling
Standard overload capability is 1.2 In for 60 s and 1.5 In for 3 s; high overload pushes to 1.5 In for 60 s and 1.85 In for 3 s, giving flexibility for different duty cycles. Cooling is forced convection with a separate internal supply at 380 V AC, and the drive is assembled in a floor-standing enclosure with separate air flows to manage thermal load. Noise level is 80 dB — a consideration for installation near occupied areas or where acoustic limits apply.
Physical footprint and integration
The floor-standing enclosure measures 2670 mm high, 4260 mm wide, and 1700 mm deep — this is a large drive requiring dedicated floor space and a reinforced foundation. Product composition includes 2 plinths, a phase-shifting transformer, medium voltage arrestors, cooling fans, human machine interface, and 24 power cells — a complete system, not just a drive module. Electrical connection uses M10 screw-type bars with clamping capacity for 6 x 40 mm² cables, entry from bottom or top, matching typical MV switchgear practices.
The drive carries CE marking and complies with EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1, covering electrical safety, EMC, and environmental protection. Pollution degree 2 per EN/IEC 61800-5-1 and overvoltage category II apply, with dielectric strength of 28 kV AC between earth and power terminals. Integrated EMC filter is included, and electrical isolation between power and control circuits is standard.
This is a large, custom-configured drive — not a stock item.
