Active production — 960 kVA medium-voltage drive for 3.3 kV motors
The ATV1200A9605555: This is a floor-standing drive cabinet with separate air flows for power and control sections — the cooling fan draws 23200 m³/h (high-efficiency variant) and the unit measures 3460 mm wide by 2740 mm tall by 1600 mm deep in the high-efficiency configuration. Forced-convection cooling with an integrated EMC filter.
Overload profile and fault coordination
The drive handles 1.2× In for 60 s under standard overload, and 1.5× In for 3 s. High-overload duty allows 1.5× In for 60 s or 1.85× In for 3 s — useful for starting high-inertia loads like large fans or centrifuges. Ground-fault protection is built into the drive. Prospective line short-circuit current withstand is 31.5 kA for 150 ms. Dielectric strength between earth and power terminals is 20 kV AC. Pollution degree 2 per IEC 61800-5-1, overvoltage category II. The 30-pulse input rectifier reduces line harmonics without external filtering. Ambient relative humidity range is 0-90 % (0-95 % optional). Vibration resistance 4.9 m/s² at 10-50 Hz.
Compliance and standards documentation
CE marked. Designed to EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1. Electrical isolation between power and control circuits. The drive is intended for both asynchronous and synchronous motors. Product composition includes two plinths, a phase-shifting transformer, medium-voltage arrestors, cooling fans, a human-machine interface, and 15 power cells. Control supply is 220 V AC at 3 kVA; internal fan supply is 380 V AC. Optional external supplies available for both.
