B&R 8I74T400750.010‑1 P74 Series High Performance Frequency Converter

Product Description

B&R 8I74T400750.010‑1 is a high‑performance frequency inverter from the ACOPOSinverter P74 series with nominal power of 7.5 kW for three‑phase 380‑500 VAC supply. It integrates built‑in EMC filter and brake chopper, equipped with POWERLINK real‑time industrial Ethernet interface and STO Safe‑Torque‑Off safety function. Supporting sensor‑less vector control and V/F control modes for asynchronous motors, it delivers precise speed and torque regulation. Digital & analog I/O channels are provided, parameters can be set via local panel or engineering software. DIN‑rail cabinet‑mount design, manufactured in Austria. Deployed as drive unit for machinery OEM integration, spare‑part replacement and production‑line retrofitting projects.
