Medium-voltage drive for heavy industrial loads
The Schneider Electric ATV1200A23005555 is an Altivar 1200 series medium-voltage AC drive rated for 1923 kW motor power with a supply voltage range of 2970 to 3630 V. This is not a 480 V class drive — it sits in the medium-voltage tier, designed for large induction and synchronous motors in applications like pumps, fans, compressors, and conveyors in mining, oil and gas, water treatment, and heavy process industries. The 30-pulse diode rectifier input provides inherent harmonic mitigation — it effectively cancels the 5th, 7th, 11th, and 13th harmonics without needing an external active filter. This matters for installations where IEEE 519 compliance is required and where transformer or generator capacity is limited.
Physical footprint and installation planning
This drive ships as a floor-standing enclosure with separate air flows for the power cells and control section. The standard-efficiency variant measures 4660 mm wide × 1600 mm deep × 2670 mm high; the high-efficiency variant is 4960 mm wide × 1700 mm deep × 2670 mm high. These dimensions dictate the floor space and lifting plan — expect a dedicated equipment room or outdoor shelter with crane access. Cooling is forced convection requiring 23,100 m³/h of air volume, and the noise level at full load is 80 dB — ear protection zones and ventilation ducting should be factored into the site layout. Operating altitude is 1000 to 2000 m with a 0.6% current derating per 100 m above 1000 m.
Overload capability and duty selection
Two overload profiles are available: standard overload allows 1.2× rated current for 60 seconds and 1.5× for 3 seconds; high overload allows 1.5× for 60 seconds and 1.85× for 3 seconds. The high-overload setting is for applications with heavy starting torque or cyclic overloads — crushers, mills, or extruders. The standard overload suits variable-torque loads like centrifugal pumps and fans. The prospective line short-circuit current withstand is 31.5 kA for 150 ms, and the dielectric strength between earth and power terminals is 20 kV AC. These figures confirm the drive's ability to ride through and clear faults on a medium-voltage distribution system without cascading damage.
The ATV1200A23005555 carries CE marking and complies with EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1. The EN/IEC 61800 series covers adjustable-speed drive safety, EMC, and functional safety — this is the standard suite for European machine builders and system integrators. The product composition includes a phase-shifting transformer, 15 power cells, medium-voltage arrestors, cooling fans, and a human-machine interface. The integrated EMC filter simplifies panel wiring — no external filter needed for most industrial environments.
