Floor-standing medium-voltage drive, 8151 kW
The ATV1200A97506666 is a Schneider Electric Altivar 1200 series AC drive rated for 8151 kW motor power at a supply voltage of 2970-3630 V. It uses a 36-pulse diode rectifier bridge input, which reduces line-side harmonics compared to 6- or 12-pulse topologies — relevant for installations where IEEE 519 compliance or utility-imposed THD limits apply. The drive is assembled in a floor-standing enclosure with separate air flows for the power section and control compartment. The enclosure is grey (RAL 7032) and measures 9770 mm wide by 3340 mm high by 1700 mm deep — this is a large-format drive that requires a dedicated equipment room or outdoor shelter with crane access for positioning.
36-pulse topology and overload profile
The 36-pulse diode rectifier bridge draws a line current of 850 A and delivers an apparent power rating of 9750 kVA. The prospective line short-circuit current withstand is 31.5 kA for 150 ms — this sets the upstream fault-clearing requirement for the supply transformer and switchgear coordination study. Overload capability is specified in two duty classes: standard overload allows 1.2× In for 60 s or 1.5× In for 3 s; high overload allows 1.5× In for 60 s or 1.85× In for 3 s. The high-overload profile is typically selected for applications with intermittent peak torque demands, such as crushers or extruders, while standard overload suits centrifugal pumps and fans. The drive includes integrated EMC filtering and provides electrical isolation between the power and control circuits. Dielectric strength is rated at 20 kV AC between earth and power terminals — a figure that confirms the drive is designed for ungrounded or high-resistance-grounded medium-voltage distribution systems.
Product composition and control interface
The ATV1200A97506666 ships as a complete assembly comprising two plinths, a phase-shifting transformer, medium-voltage arrestors, cooling fans, a human-machine interface, and 18 power cells. The phase-shifting transformer is the key component that enables the 36-pulse rectification — each power cell receives a phase-shifted secondary winding, cancelling harmonics up to the 35th order. Control wiring connects to four software-configurable analogue inputs (0-20 mA or 4-20 mA, 24 V max, 250 Ohm impedance) and one analogue output of the same type. Discrete I/O includes six digital inputs standard, expandable to ten with an optional module. The control supply requires an external 220 V AC source at 3 kVA; the cooling fans draw 380 V AC from an internal supply. Power connections use M10 screw-type bars with a clamping capacity of 6 × 40 mm² per phase (/R, /S, L3/T), with cable entry from the top or bottom. The drive is designed for vertical installation within ±10° and requires 100,000 m³/h of cooling air at standard efficiency — this airflow demand must be factored into the room HVAC design.
Standards compliance and environmental limits
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. The pollution degree is 2 per EN/IEC 61800-5-1, and the overvoltage category is II — this means the drive is intended for installation in a clean, controlled environment (typically a dedicated electrical room) rather than directly on a production floor. Relative humidity range is 0-90% (0-95% optional), and the operating position is vertical within ±10°. The noise level is 80 dB — hearing protection is required within the equipment room during operation.
