1672 kW motor power — what it means for the load
The ATV1200A20001010 is rated for 1672 kW motor output, which places it squarely in the medium-voltage drive class for large asynchronous motors — think mainline pumps, mine conveyors, or large fans where the motor frame size starts above 1 MW. Apparent power is 2000 kVA at the input, so the upstream transformer and switchgear need to be sized for that throughput, not just the motor nameplate. The supply voltage range is 2970-3630 V, meaning this drive connects to a 3.3 kV class MV bus — not a 480 V or 690 V distribution level.
48-pulse rectifier — harmonic management built in
The 48-pulse diode rectifier bridge is the key harmonic-mitigation feature: it cancels the 5th, 7th, 11th, and 13th harmonics at the input, so the drive meets IEEE 519 without external filters on most installations. That rectifier topology drives the need for the phase-shifting transformer listed in the product composition — the transformer's secondary windings are phased to feed each 6-pulse group. The integrated EMC filter covers conducted emissions per EN/IEC 61800-3, which is the drive-specific EMC standard for adjustable-speed drives.
Overload profiles and duty cycle
Two overload profiles are available: standard overload handles 1.2× rated current for 60 seconds and 1.5× for 3 seconds; high overload handles 1.5× for 60 seconds and 1.85× for 3 seconds. The high-overload profile suits applications with heavy starting torque or intermittent overloads — crushers, extruders, or centrifuge drives where the peak demand exceeds the steady-state rating.
Physical footprint and installation constraints
Cooling is forced convection with 23100 m³/h airflow — the room HVAC must handle that heat rejection, and the intake/exhaust louvres need to be sized for the full air volume. The enclosure has separate air flows for the power cells and the control section, which keeps the electronics compartment cooler and reduces the dust ingress risk on the control board.
Protection, isolation, and standards compliance
Electrical isolation between power and control circuits is standard — the control supply can be fed from an external 220 V AC source (3 kVA) or an optional 220 V AC/DC supply, keeping the control electronics on a clean supply separate from the MV bus. Ground fault protection is integrated at the drive level, so a phase-to-ground fault inside the drive or motor cable is detected and cleared by the drive itself, not by the upstream feeder breaker. The drive is CE marked and complies with EN/IEC 60204-11 (safety of machinery), EN/IEC 60529 (ingress protection), EN/IEC 61800-3 (EMC for drives), EN/IEC 61800-4 (drive ratings), and EN/IEC 61800-5-1 (electrical safety). Dielectric strength is 28 kV AC between earth and power terminals — this is the insulation test voltage, not the operating voltage, and confirms the MV isolation design.
