The Basler Electric SR8A2B05B3A is a legacy static automatic voltage regulator (AVR) from Basler’s SR series, designed to regulate the terminal voltage of AC synchronous generators by controlling current supplied to the exciter or generator field. The SR8A family can be used with brushless rotary exciters, brush-type rotary exciters, or direct generator-field excitation within its rated capacity.

- Static electronic regulator design
- Suitable for brush and brushless generators
- 125 VDC-class excitation output
- Fast voltage-regulator response
- Approx. ±0.5% regulation
- Adjustable stability circuit
- Generator paralleling provisions
- Reactive droop compensation capability
- Single- or three-phase sensing configurations
- Designed to withstand severe shock and vibration
- Suitable for demanding generator installations
- Legacy SR8A units can be upgraded using Basler’s current retrofit solution
Typical Applications
- Marine generator sets
