Product Description:
The 8I74T400110.010-1 is an AC inverter module produced by B&R Automation for the 8I7 ACOPOS Inverters series. It provides the power interface between a plant’s three-phase mains supply and a compatible synchronous or induction motor. The module converts fixed-frequency utility power into a pulse-width-modulated output, allowing a connected control system to regulate motor speed and torque in automated machinery. This conversion method supports responsive operation in positioning equipment, material-handling systems, and other applications that require controlled acceleration and deceleration.
The power section can deliver an apparent power of 3.3 kVA. Its enclosure has an IP20 protection rating, which guards against accidental contact with internal electrical parts but does not provide protection from water. When paired with a suitable motor, the inverter supports a continuous mechanical output of 1.1 kW and supplies a nominal phase current of 3 A to the stator windings. Connection to a 380 VAC network requires 5 A of line current, while operation from a 500 VAC supply reduces the demand to 3.8 A. The control electronics operate at a nominal switching frequency of 4 kHz, providing current regulation suitable for fast positioning tasks. Internal power losses produce 50 W of heat, which is removed through natural convection. Adequate vertical clearance around the module allows warm air to rise through the enclosure without forced cooling.
The housing measures 45 mm in width, 317 mm in height, and 245 mm in depth. Its panel-mounted mass is 1.705 kg, limiting the load placed on the cabinet mounting surface. Screw terminals accommodate motor wiring for installations with distributed drive and motor locations. The maximum motor-cable length is 100 m for an unshielded cable or 50 m for a shielded cable, and these limits should be observed when routing conductors through a machine. During brief acceleration periods, the inverter can supply 5 A for 2 seconds to support a rapid increase in motor torque. It can also deliver 4.5 A for as long as 60 seconds when a longer overload interval is required. After either overload period, the output must return to a level that remains within the inverter’s continuous thermal capacity.
