Product Description:
The 8I44T200300.000-1 inverter is produced by B&R Automation within the 8I4 ACOPOS Inverters series. This unit converts fixed-frequency mains power into a variable output that lets three-phase induction or synchronous motors follow speed commands in automated production lines, conveyors, and packaging equipment. It links to higher-level PLCs over an RS-485 interface for parameterization and diagnostics, and its compact housing supports dense panel layouts. The drive is intended for cabinet-mounted motion and speed control where reliable motor response is required across changing load conditions.
Its apparent power capacity is 6.6 kVA, which is the maximum combination of real and reactive power the drive can present to a motor. During continuous duty on a 240 Vac line, the inverter delivers 12.2 A of output current, while start-ups or load steps may draw up to 15.9 A from the mains. Internal control loops operate at a nominal switching frequency of 4 kHz, which sets the PWM pattern that shapes the output waveform. Normal operation dissipates 94 W of heat, so panel ventilation must remove this loss to keep semiconductor junctions within limits. The unit supports 3 kW of motor power and accepts up to 100 m of unshielded motor cable or 50 m when shielded conductors are used. The enclosure is 170 mm high, 140 mm wide, and 141.2 mm deep, which provides clear spacing data for cabinet layout.
The housing carries an IP20 protection rating, so it is intended for installation inside closed electrical cabinets where accidental contact with live parts is limited. For sixty-second overloads, the converter can supply a transient output of 18.3 A, supporting acceleration of high-inertia axes without tripping. Upstream devices should match its short-circuit withstand rating of 5000 A for coordinated interruption under fault conditions. Despite these electrical strengths, the inverter weighs only 2 kg, which keeps handling manageable during installation. The compact mass also reduces panel loading in smaller control enclosures.
