3HAB5845-1 | ABB DSQC334 | Robotics PSU for S4 S4C S4C+

Product Description

Primary Power Conversion for S4 Series Controllers

The DSQC334 (Model: DSQC334) is a specialized power supply unit (PSU) engineered for ABB’s legacy and highly reliable robot controller series, including the S4, S4C, and S4C+. As the central power distribution hub within the control cabinet, the DSQC334 (Part Number: 3HAB5845-1) converts 230 V AC input into multiple stabilized DC voltage rails. These outputs are critical for the simultaneous operation of the main CPU, digital/analog I/O boards, and the low-level logic of the drive system, ensuring deterministic robot motion and program execution.
