5225 kW medium-voltage drive with 48-pulse input
The ATV1200A62501010 is a Schneider Electric Altivar 1200 medium-voltage AC drive rated for 5225 kW motor power with 6250 kVA apparent power, designed for large asynchronous motor loads in industrial applications. The 48-pulse diode rectifier bridge input stage provides inherent harmonic mitigation, reducing line-side distortion without external filters — a key advantage for installations with strict power quality requirements. Supply voltage range is 2970 to 3630 V AC, placing this drive firmly in the medium-voltage class for applications where step-down transformers are impractical or undesirable.
Overload capability and load profile matching
The drive offers two overload profiles: standard overload at 1.2× In for 60 s or 1.5× In for 3 s, and high overload at 1.5× In for 60 s or 1.85× In for 3 s. The high-overload curve suits variable-torque loads like conveyors or extruders that need short-duration torque bursts. Line current draw is 410 A at rated conditions; the prospective short-circuit current withstand is 31.5 kA for 150 ms, which sets the SCCR coordination requirement for upstream protection.
Physical footprint and cooling architecture
The drive ships in a floor-standing enclosure with separate air flows for power and control sections. Dimensions are 3040 mm high, 9070 mm wide, and 1600 mm deep — this is a large, dedicated drive room installation, not a panel-mount unit. Forced convection cooling moves 56,400 m³/h of air at standard efficiency. The audible noise level is 80 dB — hearing protection is required in the drive room during operation. Operating altitude derating applies above 1000 m: 0.6 % current derating per 100 m up to 2000 m. Ambient relative humidity range is 0 to 90 % (0 to 95 % optional).
Standards compliance and approvals
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. Pollution degree 2 per EN/IEC 61800-5-1 applies. Dielectric strength is 28 kV AC between earth and power terminals. Electrical isolation between power and control circuits is maintained per standard.
The product composition includes the plinth, phase-shifting transformer, medium-voltage arrestors, cooling fans, HMI, and 24 power cells. This is a complete drive system, not a bare chassis — the transformer and cell architecture are integral to the 48-pulse design.
