Medium-voltage drive for synchronous and asynchronous motors
The ATV1200A16406363 is a medium-voltage AC drive from the Altivar 1200 series, designed for synchronous and asynchronous motors up to 1237 kW. Rated apparent power is 1480 kVA with a line current of 135 A, fed through a 36-pulse diode rectifier bridge that reduces line-side harmonics below IEEE 519 thresholds without external filtering. Supply voltage range is 2970-3630 V AC — this is a medium-voltage drive, not a 480 V unit, so the incoming feeder and transformer must match the class.
Overload profiles and motor starting duty
Standard overload rating: 1.2 × In for 60 seconds or 1.5 × In for 3 seconds. High overload rating: 1.5 × In for 60 seconds or 1.85 × In for 3 seconds. This covers both normal starting and heavy-duty cycling applications like crushers or conveyors. The speed range is 20-100 %, meaning the drive can regulate down to 20 % of base speed without a tachometer feedback option — adequate for centrifugal loads but not for full-torque zero-speed holding.
Physical footprint and cooling requirements
Floor-standing enclosure with separate air flows for power section and control. Standard-efficiency variant: 3960 mm wide × 1500 mm deep × 2670 mm high. High-efficiency variant: 4260 mm wide × 1600 mm deep × 2670 mm high. Forced convection cooling pulls 16500 m³/h (standard) or 19800 m³/h (high efficiency) — the room ventilation system must handle this airflow, and the intake filters need regular MRO attention. Acoustic noise is 80 dB — ear protection zone around the drive during commissioning and maintenance.
Standards compliance and isolation
CE marked. Complies with EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3 (EMC), EN/IEC 61800-4, and EN/IEC 61800-5-1. Electrical isolation between power and control circuits. Pollution degree 2 per EN/IEC 61800-5-1, overvoltage category II. Dielectric strength tested at 20 kV AC between earth and power terminals. Integrated EMC filter — no external filter needed for first environment installations.
