What this medium-voltage drive powers
The ATV1200A16003333 is a medium-voltage Altivar 1200 drive rated for 1338 kW motor power at 1600 kVA apparent power, fed from a 2970...3630 V supply through an 18-pulse diode rectifier bridge. That 18-pulse front end cuts line-side harmonics below IEEE 519 thresholds without an external filter — one less cabinet to spec and wire. It drives both synchronous and asynchronous motors, with a speed range of 20...100% and overload profiles of 1.2 In for 60 s (standard) or 1.5 In for 60 s (high overload). The 1.5 In high-overload profile matters for applications like crushers or extruders that need short torque bursts without oversizing the drive.
Floor-standing enclosure and site prep
This drive ships in a floor-standing enclosure with separate air flows for the transformer and power cells — that separation keeps the transformer heat out of the electronics compartment. Standard-efficiency configuration measures 3560 mm wide x 2820 mm high x 1500 mm deep; the high-efficiency variant widens to 3860 mm and deepens to 1600 mm. Forced convection cooling moves 29900 m³/h (standard) or 33200 m³/h (high efficiency) of air — that volume dictates the room HVAC capacity, not just a vent grille. Noise level is 80 dB, so ear protection zones around the drive are expected. Power connection uses bar terminals with M10 screws, accepting 6 x 40 mm² cable per phase, entry from bottom or top. The control supply needs an external 220 V AC source at 3 kVA; the cooling fan runs off 380 V AC internal supply.
Protection, isolation, and compliance package
Dielectric strength is 10 kV AC between earth and power terminals — that test voltage confirms the insulation coordination for a 3.3 kV class drive. Ground fault protection is built into the drive, and the prospective short-circuit current rating is 31.5 kA for 150 ms. Electrical isolation between power and control circuits is standard. The integrated EMC filter covers conducted emissions per EN/IEC 61800-3 without an add-on box. CE marked, with compliance to EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-4, and EN/IEC 61800-5-1. Operating altitude is 1000...2000 m with 0.6% current derating per 100 m above 1000 m.
I/O complement and control wiring
The drive carries 4 software-configurable analogue inputs accepting 0...20 mA or 4...20 mA at 24 V max, 250 Ohm impedance, plus 2 analogue outputs of the same type. Discrete inputs number 6 standard, expandable to 10 with an option card. Internal architecture includes a phase-shifting transformer, 9 power cells, medium-voltage arrestors, cooling fans, and a human-machine interface — all factory-integrated in the enclosure. The 18-pulse rectifier and multi-cell topology mean the drive presents a near-sinusoidal current draw to the line and a clean voltage waveform to the motor.
