11-4 Technical Specifications
590 Series DC Digital Converter
Electrical Ratings - Power Circuit
Refer to Chapter 3: “Earth Fault Monitoring Systems” for circuit breaker details.
Configuration: 590, *598 - Two anti-parallel 3-phase thyristor bridges
591, *599 - One 3-phase fully controlled thyristor bridge
* External stack options
Short circuit protection semiconductor fuses should be installed in the 3-phase supply to the 590
products. These fuses are suitable for branch circuit short-circuit protection of the solid-state
motor controllers only.
