This model belongs to the Schneider PacDrive motion control series servo power supply unit. It is a dedicated DC bus power supply module for the old Lexium/PacDrive multi-axis servo system, mainly used in packaging, machine tools, and multi-axis linkage scenarios of assembly lines. The model segmentation meaning is as follows: PS = Power Supply; 5/10/20 represent the adapted drive expansion capacity; 400 represents the adapted 400V industrial grid; 00 is the standard basic version.

Core Functional Features
Centralized bus power supply: A single module supplies the DC bus to multiple servo drives, eliminating the need for each drive to have its own rectification circuit, simplifying the wiring in the control cabinet and reducing energy consumption;
Integrated braking circuit: Built-in braking resistors allow the motor to convert its deceleration energy into local consumption, eliminating the need for an additional external braking unit;
Dual power supply output: One high-power DC bus drives the servo motor, and one independent 24V supplies power to PLC, sensors, and panels. One set of power supplies covers the entire machine’s power supply;
Flexible expansion for multiple axes: Expand the number of axes by using the DB-5 distribution box, suitable for small and medium-sized multi-axis production lines ranging from 5 to 20 axes;
Wide power grid compatibility: Supports 220V single-phase and 380/400V three-phase industrial power grids, allowing for direct deployment in new or old workshops.
Typical Application Scenarios
High-speed packaging equipment: Pillow packaging, vertical bag-making machines with multi-axis film movement and cutting linkage control;
Specialized CNC machines: Small milling and grinding equipment, robotic joints with multi-axis servo clusters for power supply;
Workstation on the production line: Sorting and transplanting, reciprocating positioning equipment with multi-axis synchronous drive;
Existing old equipment spare parts: Fault replacement parts for outdated PacDrive systems, the same model can be directly plugged in and replaced.
