Technical Specifications
-
Input: three-phase 200–240 V AC
-
Output: regulated DC bus for servo drives
-
Built-in: surge suppression, EMI filter, overvoltage/undervoltage/overcurrent protection
-

Functional Features
-
Shared DC bus across axes
-
Regenerative energy shared on common bus
-
Reduces harmonic sources from parallel switch-mode supplies
Application Scenarios
Robotics, semiconductor equipment, high-end CNC, multi-axis gantry systems.
Working Principle
Three-phase AC enters bridge rectifier → filter capacitors smooth DC → DC bus bar distributes to drive DC links → protection circuits monitor bus voltage and temperature.
Installation Requirements
Use proper three-phase breaker and contactor. Leave vertical airflow clearance. Torque DC bus copper bars to manual specification.
Usage Notes
Verify drive-side bus voltage rating before connection. Discharge bus capacitors fully before any maintenance.
