What this MV drive is and the load it handles
The ATV1200A35006060 is a medium-voltage variable speed drive from the Altivar 1200 series, rated for 2926 kW motor power at a supply voltage of 2970 to 3630 V AC (3.3 kV class). It drives both synchronous and asynchronous motors — a single drive platform for pump, fan, compressor, or conveyor loads in the 2-3 MW range. The 30-pulse diode rectifier input stage keeps line current harmonics low enough to meet IEEE 519 without external filters — a key advantage for installations where the utility demands clean power at the point of common coupling. The integrated EMC filter covers conducted emissions per EN/IEC 61800-3. Line current draw is 410 A at the rated apparent power of 3500 kVA. Prospective short-circuit withstand is 31.5 kA for 150 ms — the drive's input section is built to ride through a fault without upstream breaker coordination headaches.
Overload profile and protection envelope
Overload capability is defined for two duty classes: standard overload allows 1.2× In for 60 s and 1.5× In for 3 s; high overload allows 1.5× In for 60 s and 1.85× In for 3 s. The 60-second window at 1.5× In in high-overload mode is the spec to check if the application has a crusher or centrifuge start cycle that pulls heavy current through the ramp. Ground fault protection is integral to the drive. Dielectric strength is 20 kV AC between earth and power terminals, and isolation between power and control circuits is electrical — no optocoupler drift to track over temperature. Pollution degree 2 per EN/IEC 61800-5-1 and overvoltage category II define the drive's installation environment: it expects a clean, controlled electrical room, not a dusty substation floor. Operating altitude derating starts at 1000 m, 0.6 % per 100 m up to 2000 m — factor that into the site survey before the plinth is poured.
Physical footprint and cooling demand
The drive ships in a floor-standing enclosure measuring 6070 mm wide by 1700 mm deep by 2670 mm high. The enclosure colour is grey RAL 7032. Cooling is forced convection with separate air flows for power and control sections, moving 29700 m³/h of air — the room HVAC must handle that rejection, not just the drive's own fans. Acoustic noise is 80 dB — ear protection zone signage is mandatory near the enclosure. The operating position is vertical ±10°, and vibration resistance is 4.9 m/s² at 10 to 50 Hz. Product composition includes 15 power cells, a phase-shifting transformer, medium-voltage arrestors, cooling fans, and a human-machine interface. Power connections are bar-type screw terminals M10, accepting 6 × 40 mm² cable per phase, entry from top or bottom.
Control I/O and auxiliary supply options
The control section offers 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. Control power requires an external 220 V AC supply at 3 kVA. The cooling fan circuit needs a separate 380 V AC feed — both can be supplied as external options. This split-supply architecture means the control cabinet must provide two independent feeds, not a single transformer tap. Speed range is 20 to 100 %. Relative humidity tolerance is 0 to 90 % non-condensing, with an optional 95 % rating.
Production status and sourcing posture
Sourced to order against your BOM quantity through independent distribution channels. Compliance documentation includes CE marking and conformance to EN/IEC 60204-11, 60529, 61800-3, 61800-4, and 61800-5-1. The drive meets the relevant machinery directive and EMC standards for industrial environments.
