Product Description:

The 8I64T400220.000-1 is an ACOPOS Inverter which is designed to provide stability and system integration to ensure dependable performance within intricate automation systems. Manufactured by B & R Automation, this inverter has a three-phase input voltage range of 380 VAC (-15%) to 500 VAC (+10%), hence suitable for industrial power systems over the world.

This inverter has a nominal clock frequency of 4 kHz to offer high-quality modulation of motors and reliable control performance. This inverter has a 50-60 Hz input frequency with a tolerance of ± 5 % for stable operation under standard frequency changes. This inverter produces an output voltage of 24VDC with a minimum voltage of 19VDC and a maximum of 30VDC in order to provide the consistency of voltage for the attached control units. The transient current of this inverter is 8.3 A and can perform for 60 seconds to meet the short-time overload requirements. The maximum output current of this inverter is 100 mA, which is enough for the transmission of control signals. The 500 VAC input apparent power of this inverter is 5.9 kVA to support medium-duty motor drives. At maximum output current conditions, the 8I64T400220.000-1 inverter has a 79 W power dissipation to permit efficient thermal design in control cabinets.

The communication interfaces of this inverter comprise both X2X and CANopen for providing effortless integration with B & R Automation systems. The environmental durability of the 8I64T400220.000-1 is assured through adherence to IEC 60721-3-3 classification 3C3 (chemical effect) and 3S2 (mechanical stress). These ratings make this inverter appropriate for operation in environments with corrosive gases and medium mechanical stresses. This inverter is designed for vertical mounting with ±10% positional tolerance to ensure adequate airflow and cooling performance.
