ABB ACS880-01-07A2-3+K492

The ABB ACS880-01-07A2-3+K492 is a premium wall-mounted single industrial variable frequency drive equipped with the factory-installed +K492 integrated internal brake chopper module, belonging to ABB’s flagship ACS880 high-performance drive series for precise AC motor regulationmjplc.com. Designed for 3-phase 380–415V AC power supply, its rated output current reaches 7.2A, supporting a nominal driving power of 3kW under light overload operation and 2.2kW for heavy-duty working scenarios, suitable for squirrel-cage induction motors, permanent magnet motors and synchronous reluctance motors with ABB’s patented Direct Torque Control (DTC) technology delivering ultra-fast torque response within 5ms.

The integrated K492 brake chopper efficiently absorbs regenerative energy generated during motor quick deceleration, emergency stop and frequent reversing operations when matched with external brake resistors, preventing DC bus overvoltage faults and ensuring stable operation of high-inertia loads such as conveyors, small cranes and fansmjplc.com. STO (Safe Torque Off) function is embedded as standard to meet global machinery safety requirements, together with comprehensive built-in protections including overcurrent, overvoltage, overtemperature, overload and phase loss protection. This drive adopts industrial-grade coated circuit boards, standard IP21 enclosure protection and built-in input choke to suppress grid harmonic interference, achieving an operational efficiency up to 98%. It supports flexible fieldbus expansion, rich digital and analog I/O terminals, plug-and-play configuration via Drive Composer PC tool and portable memory unit backup. Featuring compact R1 frame size, easy wall-mounted installation and long service cycle up to 9 years under regular maintenance, it serves as a reliable solution for medium-precision industrial automation, water treatment pumps, ventilation fans and light-duty material handling equipment with frequent braking demandsABB Group.
