It is a crucial part of industrial automation since it incorporates several aspects that make it run smoothly and efficiently.

Technical Specifications:

The ATV312HD11N4 variable speed drive operates at 50 € “60 Hz and needs 380V. Its flexibility is a bonus as industrial voltage variations are common. In diverse operational conditions, the drive can deliver power efficiently and steadily by managing a maximum line current of 37.2 A at 380 V and 28.4 A at 500 V.

This drive meets electromagnetic compatibility standards with a 25 kVA apparent power rating and EMC filter. EMC filters reduce device interference, improving system reliability. The ATV312HD11N4's inherent maximum transient current capacity of 41.6 A for 60 seconds protects coupled motors from short-term current surges.

The ATV312HD11N4 provides vector control and factory-adjusted torque due to its high-tech motor control. These control methods optimize motor performance throughout a wide speed range by accurately managing motors.

The drive has a 100 mA rating and an internal supply that can handle logic inputs ranging from 19 to 30 V, so it's rather safe from overloads and short circuits. Thanks to this function, the device's durability is boosted and its operating stability is guaranteed for the long haul.

Performance:

When it comes to performance and dependability, the Schneider Electric ATV312HD11N4 is second to none. Its power dissipation is 397 W at nominal load, therefore it uses energy efficiently and performs well.

Various motor control needs in industrial contexts can be met by this device, which offers a wide speed range of 1 to 50. Ensuring full safety throughout operation, its strong design features protective mechanisms against input phase breaks, overvoltage, undervoltage, and motor phase breaks.

An output frequency range of 0 to 500 Hz and the capacity to sustain a continuous output current of 27.7 A make the ATV312HD11N4 incredibly versatile. It can be customized to meet individual operational needs by adjusting its switching frequency from 2-16 kHz, with a nominal setting of 4 kHz.

Environmental and Safety Features:

ATV312HD11N4 meets all safety and environmental standards. Its dielectric strength is 2410 V DC between the earth and power terminals and 3400 V AC between the control and power terminals. This drive's excellent insulation ensures its long-term reliability and security in harsh industrial environments. The ATV312HD11N4 works consistently up to 60 °C (with derating). It meets IEC 60068-2-3 and can withstand 5%-95% relative humidity without condensation.
