Product Description:
The 8I74S200075.010-1 inverter is produced by B&R Automation as part of the 8I7 ACOPOS Inverters series. It converts the incoming utility supply into regulated motor voltage and frequency and is intended for use with the ACOPOS motion platform. Within automated lines, the device provides speed control for small conveyors, indexing tables, or pump drives, allowing precise acceleration profiles and reduced energy consumption compared with fixed-speed starters.
Its continuous motor output is rated at 0.75 kW, which indicates the mechanical shaft power available to the connected machine without derating. The inverter’s apparent input demand reaches 2.0 kVA, so upstream fusing and wiring must accommodate that level of volt-ampere loading. Because the power stage is designed for a single-phase supply, installation requires two supply conductors and a protective earth connection. When the mains supply is 200 VAC, the module draws 10.1 A. At 240 VAC, the current decreases to 8.5 A because the higher voltage delivers the same power with less amperage. Control integration is handled by six digital inputs, three analog inputs, and two relay outputs, while the analog output channel provides 10-bit resolution. A 40 Ω external brake resistor can be connected to dissipate regenerative energy during rapid deceleration.
Internal charge storage is provided by an 880 µF DC-link capacitor. The DC-link voltage reaches 283 V with a 200 VAC line and 339 V with a 240 VAC line, establishing the modulation range available to the motor terminals. During regenerative braking, the brake transistor can switch up to 395 V to the braking circuit to keep the bus voltage within operating limits. Estimated power loss is 51 W, so cabinet ventilation must remove the resulting heat during continuous operation. The housing has an IP20 protection rating, indicating finger-safe openings and suitability for installation inside an electrical enclosure.
