Product Description:
The 8I74T400150.010-1 is an AC drive module from B & R Automation that belongs to the 8I7 ACOPOS Inverters series. As a line-side inverter, it converts three-phase mains power into a pulse-width-modulated output that governs induction motor speed and torque in automated machinery. By integrating with the ACOPOS axis platform, the unit supplies controlled electrical power to conveyor, pump, and positioning applications.
Apparent power capability reaches 4.2 kVA, so the inverter can supply sufficient volt-ampere reserve for dynamic load changes while maintaining the rated motor output of 1.5 kW. Under continuous operation, the drive delivers a nominal phase current of 4.1 A, and its protective enclosure meets the IP20 rating for installation inside ventilated control cabinets. When energized, the power section draws an inrush current of 10 A, which should be considered when selecting upstream fuses and contactors. Additional operating data include a mains current of 6.5 A at 380 VAC, a transient current allowance of 6.2 A for 60 seconds, and a nominal clock frequency of 4 kHz that affects switching losses. Thermal loading is limited by 63 W of power dissipation, which is managed through cabinet airflow. The housing measures 245 mm deep and 317 mm high, and the motor lead may extend up to 50 m when a shielded cable is used.
A prospective fault is contained by a withstand level of 5 kA, enabling the drive to operate with branch circuit breakers rated for moderate industrial panels. For flexible machine layouts, non-shielded motor cabling can be run up to 100 m without violating EMC guidelines. The slim profile is only 45 mm wide, conserving rail space in densely packed control cabinets. The installation weight is 1.705 kg, which reduces the load placed on cabinet mounting hardware. These dimensions allow the module to fit into narrow panel spaces while maintaining suitable clearance for wiring and airflow.
