Product Description:
The 8I74T400750.01P-1 is an AC inverter module produced by B&R Automation for the 8I7 ACOPOS Inverters series. It channels three-phase mains energy into a controlled DC link and then generates a variable AC output, allowing plant controllers to command torque and speed on connected motors. The device is suited for conveyor zones, secondary packaging machines, and compact machining centers that need decentralized drive power close to the load while still providing diagnostic access through built-in field I/O ports and the motion bus interface.
This model supplies up to 16.2 kVA to the DC link and matches a motor rating of 7.5 kW. A continuous load is supported by a nominal output current of 17 A, while the three-phase line draws 26.5 A at 380 VAC under full load. An internal DC-bus capacitance of 1110 µF stores energy during brief mains dips and helps smooth peak demand. Switching and magnetic losses appear as 263 W of heat, so the enclosure requires adequate cabinet airflow. Control wiring is supported by six digital inputs, three analog inputs, and two relay outputs for local limit sensing or contactor control. The housing measures 150 mm in width, 232 mm in depth, and 308 mm in height for panel mounting.
During acceleration or shock loading, the drive tolerates a transient current of 25.5 A for sixty seconds, and external braking resistors as low as 27 Ω can be connected to dissipate regenerated energy. On 500 VAC networks, the supply draw falls to 18.7 A because the higher line voltage reduces current for the same power level. The unit weighs 4.20 kg, which keeps handling manageable while still providing a stable thermal mass. Using an appropriate brake resistor together with the internal energy storage helps limit DC-bus overvoltage during rapid deceleration.
