Atlas Copco DSQC345E Inmotion Servo Drive Module

Atlas Copco's DSQC345E Inmotion Servo Drive Module is the DC-link rectifier used in the Inmotion servo drive family to generate the high-voltage DC bus that powers the servo amplifiers. Also cataloged as ABB 3HAB8101-14 (Rectifier DC-Link DC4), this unit measures 6.875 in long, 4.875 in wide, and 14.5 in high (roughly 174.6 x 123.8 x 368.3 mm) and is commonly referenced for replacement or repair under the same DSQC345E family. Designed for robotics and automation applications that deploy Atlas Copco's Inmotion drives (notably the S4C series), the DSQC345E handles the rectification function that feeds the DC link from AC mains and provides a stable supply for precise servo control. The 06B revision variant appears in distributor catalogs alongside 3HAB8101-14 cross-references, confirming its role as the DC-link rectifier module within the Inmotion servo drive architecture.
