8I76T400150.0P-000
The 8I76T400150.0P-000 inverter from B & R Automation is a robust solution in the 8I7 ACOPOS Inverters series, engineered for demanding industrial automation. It delivers a rated motor output of 1.5 kW (2 HP) and operates from a three-phase input voltage of 380–500 VAC (–15%/+10%). Designed as a Tie Rod assembly, it is constructed of high-strength 42CrMo4 material with a Phosphated coating for corrosion resistance. The unit measures 1500 mm in length and weighs 19.2 kg, providing a compact yet durable form factor for machine integration.
Technical capabilities of the 8I76T400150.0P-000 include an apparent power rating of 3.8 kVA at 500 VAC and a peak surge current limit of 10 A, ensuring safe startup and motor protection. Mains current draw is 5.8 A at 380 VAC and 4.4 A at 500 VAC, while the maximum short-circuit current at the connection point is 5 kA. The inverter integrates an internal EMC filter compatible with up to 50 m of shielded cable or 100 m of non-shielded cable without external filtering. For extended cable runs or higher immunity requirements, an optional 8I0FT015.200-1 filter enables C1 operation up to 20 m and C2 up to 50 m of motor cable.
Operational features include an adjustable output frequency range of 0.1–599 Hz and a nominal clock frequency of 4 kHz, which can be tuned between 2 kHz and 16 kHz for optimized acoustic and dynamic performance. When paired with a braking resistor, the inverter can deliver up to 170% of rated braking torque and sustain a transient current of 6.2 A for 60 seconds. No output current derating is required up to 50 °C ambient temperature at the nominal clock frequency, with a current reduction rate of 1% per 100 m above 1000 m altitude. Normal operation at full load dissipates 63 W of heat, and the internal design features a Machined end finish, quenched and tempered heat treatment, 280–320 HB surface hardness, 1100 MPa tensile strength, and 850 MPa yield strength to ensure long-term mechanical integrity.
Integration into industrial systems is streamlined by the inverter’s standardized tie-rod dimensions, M76 thread diameter, 4.0 mm thread pitch, and 6g thread tolerance, simplifying mounting and alignment procedures. The robust 42CrMo4 construction and Phosphated surface treatment resist environmental stress in assembly lines, packaging machines, and conveyor drives. Its built-in EMC filter and optional external filtering solutions support reliable operation in electrically noisy environments. Overall, the 8I76T400150.0P-000 inverter is ideally suited for applications requiring precise speed control, high reliability, and easy integration into modern automation architectures.
