Product Description:

The 8I76S200037.00-000 is a compact AC inverter produced by B&R Automation within the 8I7 ACOPOS Inverters series. It interfaces between a 240 Vac mains supply and a three-phase induction motor, regulating voltage and frequency to match commanded speed and torque profiles in automated machinery. Its design targets distributed motion axes in packaging and material-handling lines where cabinet space is restricted.

At the motor terminals, the unit supports a continuous mechanical output of 0.37 kW, suited for fractional-horsepower drive sections such as indexing tables or small pumps. The apparent power drawn from a 240 Vac supply reaches 1 kVA, which indicates the combined real and reactive demand the installation wiring must accommodate. Nominal mains current under full load is 4.3 A, which helps with circuit breaker selection and conductor thermal sizing. The housing has a width of 45 mm, allowing high-density mounting on DIN rails, and its height is 325 mm, leaving clearance for cable bend radii inside shallow enclosures. A built-in Class C3 line filter permits motor cable runs up to 10 m without exceeding conducted emission limits.

Thermal management is aided by a power dissipation of 38 W, so forced ventilation requirements remain moderate. During energization, the capacitors draw an inrush current of 9.6 A, so protective devices should be sized accordingly. The device can withstand a maximum assumed short-circuit current of 1 kA, enabling coordination with upstream protective equipment in industrial panels. Total mass is 2.4 kg, which simplifies vertical mounting on machine frames. A depth of 232 mm keeps cabinet intrusion low, and the enclosure includes an integrated brake chopper to absorb regenerated energy during rapid deceleration as well as an integrated EMC filter that attenuates high-frequency noise on the supply conductors.
