UNITROL® 5000 Excitation Systems
A microprocessor-based static excitation system for medium and high power output.

Hardware complexity:

- Due to the system architecture and the use of ARCnet® field bus system, the maximum quantity of inputs/outputs for internal and external use is practically not limited. 
- The use of decentralized converter electronic modules allows the control of several parallel thyristor bridges. 
- Reduced wiring complexity and volume for the interconnection of the system components due to the use of ARCnet® field bus.

UNITROL® F Static Excitation Systems
UNITROL® F Static Excitations are microprocessor-based systems for synchronous machines of small and medium sizes.

Application range of Excitation Systems:
 Static Excitation Systems (SES) with output currents up to approx. 1000 ADC:

- Highly standardized single channel systems with few options for max 500VAC and system currents 370 / 540 / 780ADC 
- Custom-made single and dual channel systems
