ABB ACS800-104-0105-3+Q967
Product Name
ABB ACS800-104-0105-3+Q967 Air-Cooled Inverter Module (Multidrive, 105 A Output, 400 V Class, with Safe Torque Off/STO Option +Q967).
Product Description
The ABB ACS800-104-0105-3+Q967 is a 3-phase air-cooled inverter module for ACS800 Multidrive systems, engineered for cabinet mounting in industrial automation, process control, and heavy-duty motion applications (e.g., pumps, fans, conveyors, compressors, and mill drives). It operates from a shared DC bus, enabling high power density, parallel operation for redundancy/higher power, and optimized cabinet integration with a bookshelf form factor, auto-regulating cooling fan, and quick-connect terminals for motor wiring. Equipped with ABB’s Direct Torque Control (DTC) for precise speed/torque regulation across the speed range, it includes the +Q967 Safe Torque Off (STO) option—an ASTO board-based safety function compliant with EN 61800-5-2, EN ISO 13849-1, and IEC 61508—to disable output power semiconductors and prevent unintended motor rotation while maintaining power to control electronics. Rated for 105 A continuous output current (400 V class), it is ideal for demanding multi-axis and process-critical installations requiring both performance and functional safety.
