Brush less Digital Excitation & Control system for 500KW to 60MW Synchronous Machine

Compact Excitation System for 5MW or Below Synchronous Machines

Amtech offers a high powered, low-cost digital excitation control system. This environmentally rugged product is ideally suited for controlling the output of brush-less excited synchronous generators up to 5MW. This has a very impressive 7Adc output from a pulse width modulated power stage. It is perfect for machines that will be paralleled to other generators and/or to the utility system. It is ideal for distributed generation, co-generation and peak shaving applications. It is easy to use, and it has communications capability with a PC. It utilizes microprocessor technology and control algorithms pioneered by us for longer than a decade. It shares many features and functions of our larger excitation control systems. It is fifth generation of microprocessor-based excitation system.
