The 598/9P External Stack Controller Assembly provides the Hardware necessary to interface the 590Plus Control Door to an existing 3 Phase Stack assembly. The Design assumes that a Fully Controlled 3 Phase Six Pulse Converter exists which is complete with Thyristor Suppression, Current Feedback, Temperature Monitoring and Suitable Fusing.
The External Stack Controller Module provides: –
• Thyristor Firing Signals;
• Thyristor Firing Pulse Transformers;
• ACCT Feedback Rectification and Scaling;
• Armature Voltage Feedback Interface;
• Coding and Phase Rotation Interface;
• Mains Present Monitoring
• Heatsink Over-temperature Input;
• Field Power Modules and Input / Output Terminations;
• Field Current Monitoring and Scaling;
• All Standard 590Plus I/O Terminations.
