Medium-voltage drive for large asynchronous motors
The ATV1200A95301010 is a medium-voltage drive in the Altivar 1200 series, rated for 7967 kW motor power at 9530 kVA apparent power — sized for large pumps, conveyors, fans, and compressors in mining, mineral processing, and heavy industrial plants. Input voltage range is 2970 to 3630 V AC, with a 48-pulse diode rectifier bridge that keeps line harmonics low enough to avoid external filters in most installations.
Floor-standing footprint and site prep
This drive ships in a floor-standing enclosure with separate air flows for the power section and control compartment — plan for a footprint of 14.48 m wide by 1.6 m deep, 3.04 m tall, with 140,000 m³/h of cooling air volume. Operating position is vertical ±10 degrees; altitude derating starts at 1000 m at 0.6% per 100 m. Ambient relative humidity 0-90% (95% optional). Noise level is 80 dB — hearing protection zone likely required.
Overload profile and protection
Standard overload rating is 1.2× In for 60 seconds and 1.5× In for 3 seconds; high overload goes to 1.5× In for 60 s and 1.85× In for 3 s. Ground fault protection is integrated into the drive. Dielectric strength is 28 kV AC between earth and power terminals. Prospective short-circuit current withstand is 31.5 kA for 150 ms — coordination with upstream protection is critical.
Control wiring and I/O complement
Control supply requires an external 220 V AC source at 3 kVA (optional 220 V AC/DC). The drive includes 4 software-configurable analogue inputs (0-20 mA / 4-20 mA, 250 Ω impedance), 1 analogue output (same range), and 6 discrete inputs (10 optional). Electrical isolation between power and control circuits is maintained throughout. Pollution degree 2 per EN/IEC 61800-5-1, overvoltage category II.
Marked CE, compliant with EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1. Integrated EMC filter is standard. Product composition includes 2 plinths, a phase-shifting transformer, medium-voltage arrestors, cooling fans, a human-machine interface, and 24 power cells — each field-replaceable.
