Medium-voltage drive for large synchronous and asynchronous motors
The Schneider Electric ATV1200A47604242 is an Altivar 1200 series medium-voltage AC drive designed to control synchronous and asynchronous motors up to 3979 kW. With an apparent power rating of 4760 kVA and a supply voltage range of 2970 to 3630 V, this drive is sized for large industrial loads such as pumps, compressors, conveyors, and fans in heavy process industries. The 24-pulse diode rectifier input topology reduces line-side harmonics below IEEE 519 thresholds without external filters — a key advantage for installations with weak grid connections or strict power quality requirements.
Overload capacity and motor starting duty
The drive delivers 1.2× rated current for 60 seconds under standard overload and 1.5× for 3 seconds, covering normal motor starting and process overloads. For high-overload applications, it sustains 1.5× rated current for 60 seconds and 1.85× for 3 seconds — suited for crushers, mills, or extruders with high breakaway torque demands. The speed range of 20 to 100 percent supports constant-torque applications down to 20% base speed, with forced-convection cooling maintaining thermal stability across the operating band.
Physical footprint and enclosure integration
Housed in a floor-standing enclosure with separate air flows, the drive measures 2740 mm high, 6670 mm wide, and 1800 mm deep — requiring a dedicated equipment room or outdoor kiosk with adequate floor loading and ventilation. The forced-convection cooling system moves 70,000 m³/h of air at standard efficiency, so the installation site must provide unobstructed intake and exhaust paths with sufficient free area to avoid static pressure buildup. Operating position is vertical within ±10 degrees, and the enclosure is rated for pollution degree 2 per EN/IEC 61800-5-1 — typical for controlled electrical rooms with non-conductive dust.
Standards compliance and regulatory acceptance
CE marked and designed to EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3 (EMC), EN/IEC 61800-4, and EN/IEC 61800-5-1 — covering electrical safety, EMC emission/immunity, and functional safety for adjustable-speed drives. Electrical isolation between power and control circuits, plus an integrated EMC filter, simplifies panel design and reduces external filtering components for most installations. The drive includes ground fault protection and a dielectric strength rating of 20 kV AC between earth and power terminals, meeting the isolation requirements for medium-voltage systems.
