High-power DC power supply

1. High power density: 50kW for a single module and 500kW for a single cabinet
2. Master-slave multi-machine parallel connection technology: no parallel connection, parallel connection does not affect the response speed
3. Redundant design: any combination of modules and cabinets can be output
4. CPCI central control unit: the interface is fully optical fiber isolated
5. Electromagnetic compatibility design: electromagnetic shielding cabinet
6. Constant voltage, constant current and constant power can be selected
7. Perfect protection scheme
8. A variety of communication modes are optional
