ABB 3HAB5845-1 DSQC 334 S4C Power Supply Unit Specifications

ABB DSQC 334 3HAB5845-1 Power Supply Unit The ABB DSQC 334 (part number 3HAB5845-1) is an internal power supply unit designed for ABB S4C industrial robot controller systems. It performs AC-to-DC power conversion and distribution, delivering up to 6 A continuous output at 24 V DC to power the controller's internal electronics and associated field I/O circuitry. Housed in a cabinet-mountable assembly, it serves as a critical replacement power module for robotic control architectures. Technical Specification Parameter Specification Model DSQC 334 Brand ABB ABB Part Number 3HAB5845-1 Product Type Robot Controller Power Supply Compatible Controller Family ABB S4C robot controllers I/O Supply Rating 24 V DC Maximum 24 V I/O Load 6 A continuous Mounting Type Installed within robot controller cabinet Dimensions 18.5 × 22.4 × 24.1 cm (7.3 × 8.8 × 9.5 in) Weight 4.9 kg (10 lbs 14.4 oz) / 1 kg shipping weight (per alternate supplier data) Power Conversion and Controller Distribution The DSQC 334 unit converts incoming utility voltage to supply stable DC operating power across the backplane of S4C robot controllers. It features a dedicated 24 V DC output channel rated for up to 6 A continuous current, which feeds active logic modules, safety interlocks, and external peripheral I/O interfaces connected to the robot arm. System Integration and Physical Enclosure Engineered for internal cabinet mounting within S4C enclosure frames, the DSQC 334 interfaces directly with the controller's power distribution bus. Its physical footprint measures 18.5 × 22.4 × 24.1 cm with an operational weight of 4.9 kg, enabling direct replacement of legacy units during scheduled maintenance or system rebuilds.
