UNITROL® F AVR systems are microprocessor-based voltage regulators for small and medium power applications.
Application range:
Automatic Voltage Regulator (AVR) systems for exciter machines with output currents:
- from 1 to 75 ADC with supply voltage up to 400 VAC 50/60 Hz with fully controlled single or three phase thyristor bridge
- from 1 to 25 ADC with supply voltage up to 250 VAC or DC. Used for DC or AC 50/60Hz supply using an IGBT chopper stage
Highly standardized single channel systems with few options and custom-made single and dual channel systems available.
