Product Description

The 8I74T400750.01P-1 ACOPOSinverter P74 from B&R is a powerful and versatile device designed for advanced motor control applications. With a robust power rating of 7.5 kW (10 HP), this inverter operates efficiently with an input voltage range of 3x 380 VAC -15% to 500 VAC +10% and an input frequency of 50 to 60 Hz ~5%. It supports multiple motor control profiles, including asynchronous motors with flux vector control without an encoder, as well as various voltage/frequency ratio options such as the U/f curve with 2 or 5 points, a pump/fan profile with a quadratic curve, and an energy-saving profile. This flexibility allows the inverter to adapt to diverse industrial requirements, providing both efficiency and precision.

The 8I74T400750.01P-1 inverter is equipped with extensive protection functions, including thermal protection against overheating, short-circuit protection between motor phases, overcurrent protection between output phases and ground, overvoltage protection on the DC bus, and overspeed protection. These features ensure reliable operation even under demanding conditions. It also includes two relay outputs rated at 30 VDC / 250 VAC, 24 VDC digital outputs with 100 mA capacity, and analog outputs ranging from 0 to 10 V or 0 to 20 mA, providing comprehensive control and monitoring capabilities.

The inverter also integrates an EMC filter, ensuring compliance with electromagnetic compatibility standards, and features an adjustable control capacity that supports both source and sink configurations. With a swift switching time of 2 ms, integrated diagnostic functions, and forced air cooling, the 8I74T400750.01P-1 is engineered for optimal performance in various environmental conditions. Its durability is further supported by an UL E225616 environmental rating, making it a reliable choice for industrial automation tasks.
