What this MV drive is and where it lands
The ATV1200A69005555 is a medium-voltage drive from the Altivar 1200 family, rated for 5768 kW motor power with a supply voltage range of 2970 to 3630 V. It is a multi-cell topology drive — the product composition includes a phase-shifting transformer, 15 power cells, medium-voltage arrestors, cooling fans, and a human-machine interface, all housed in a floor-standing enclosure with separate air flows for power and control sections. The 30-pulse diode rectifier input stage delivers very low line-current harmonic distortion, which simplifies compliance with EN/IEC 61800-3 EMC requirements without additional external filtering. The integrated EMC filter is standard. This drive is designed for large asynchronous and synchronous motors in heavy industrial applications — pumps, fans, compressors, conveyors, and mills where the load exceeds the practical range of low-voltage drives.
Physical footprint and site preparation
The enclosure measures 1700 mm deep, 8970 mm wide, and 3040 mm high — a substantial floor-standing footprint that requires a dedicated equipment room or outdoor shelter with a reinforced floor. The operating position is vertical ±10 degrees. Forced convection cooling moves 90,000 m³/h of air at standard efficiency. The noise level is 80 dB — hearing protection is necessary within the operating zone. The enclosure colour is grey RAL 7032. Site altitude must be accounted for: the drive is rated for operation from 1000 m to 2000 m with a current derating of 0.6% per 100 m above 1000 m. Relative humidity limits are 0-90% (0-95% optional).
Overload capability and fault coordination
The drive offers two overload profiles. Standard overload: 1.2 × In for 60 s and 1.5 × In for 3 s. High overload: 1.5 × In for 60 s and 1.85 × In for 3 s. The selection determines whether the drive is sized for normal duty (pumps/fans) or heavy duty (crushers/extruders). The prospective line short-circuit current rating is 31.5 kA for 150 ms, which drives the upstream fuse or breaker coordination. Dielectric strength between earth and power terminals is 20 kV AC. Ground fault protection is built into the drive. Electrical isolation between power and control circuits is standard, and the pollution degree is 2 per EN/IEC 61800-5-1. Overvoltage category is II.
Control I/O and compliance suite
The drive includes 4 software-configurable analogue inputs (0-20 mA / 4-20 mA, 24 V max, 250 Ω impedance) and 1 analogue output of the same type. Discrete inputs are 6 standard, expandable to 10. An external control supply of 220 V AC at 3 kVA is required; the internal cooling fan supply is 380 V AC. Compliance documentation covers EN/IEC 60204-11 (machinery safety), EN/IEC 60529 (enclosure protection), EN/IEC 61800-3 (EMC for drives), EN/IEC 61800-4 (adjustable speed drives), and EN/IEC 61800-5-1 (electrical safety). CE marking is applied.
