48-pulse architecture for medium-voltage motor control
The Schneider Electric ATV1200A23401010 is a medium-voltage AC drive from the Altivar 1200 family, rated for 1956 kW motor power with 2340 kVA apparent power. Its 48-pulse diode rectifier bridge input delivers low harmonic distortion without a separate filter — a key advantage for installations where IEEE 519 compliance is a constraint. Supply voltage range is 2970–3630 V, placing it in the medium-voltage class. The output voltage is limited to or below the supply voltage, so the motor nameplate voltage must align with the available line feed.
Overload profile and thermal budget
The overload withstand table defines two duty cycles: standard overload handles 1.2× In for 60 s and 1.5× In for 3 s; high overload pushes to 1.5× In for 60 s and 1.85× In for 3 s. This means the drive can ride through a crusher jam or a conveyor start without tripping, but the high-overload window is short — the 3 s limit at 1.85× In is a hard ceiling, not a suggestion. Forced convection cooling moves 23,100 m³/h through the floor-standing enclosure. The noise level is 80 dB — ear protection zones around the drive are expected in a typical installation.
Architecture and internal composition
The drive is built from 24 power cells fed by a phase-shifting transformer, plus medium-voltage arrestors, cooling fans, and a human-machine interface, all housed in a grey (RAL 7032) floor-standing enclosure with separate air flows for power and control sections. Electrical isolation between power and control means the control electronics can be safely referenced to earth while the power section runs at medium voltage — a standard safety separation for drives at this class. Dielectric strength is 28 kV AC between earth and power terminals, confirming the insulation coordination for a 3.3 kV class system.
The drive 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. Prospective line short-circuit current withstand is 31.5 kA for 150 ms — this sets the upstream fuse or breaker requirement for coordination. The integrated EMC filter covers conducted emissions for the first environment per EN/IEC 61800-3.
Sourcing and lifecycle position
Sourced through independent distribution channels. For a drive of this scale — 1956 kW, floor-standing, 24 power cells — the quote should include the full enclosure dimensions (1700 mm depth, 5160 mm width, 2670 mm height) for site access planning.
