Generator Automatic Voltage Regulator AVR AN-5-201

• Three-phase AC input (main winding) with auxiliary winding input.
• Voltage range: Main winding 400 VAC (nominal); auxiliary winding 55–200 VAC.
• Supports self-excitation start-up (residual voltage ≥ 5 VAC/30Hz required for start-up).
• Compatible with 50Hz/60Hz systems (automatically adaptive without manual switching).

• DC excitation output: Continuous current up to 5 A; instantaneous peak current 12 A (≤ 10 seconds).
• Output voltage range: 50–120 VDC (dynamically adjusts according to generator speed/load).

• Steady-state voltage regulation: ≤ ±1.5% RMS.
• Dynamic response: Recovery time ≤ 400 ms (when the voltage drops to 90% of the rated value) (derived from parameters of similar AVR models).

• Built-in over-excitation protection.
• Short-circuit current limitation: Not explicitly specified in available data.
• Under-voltage/over-voltage protection: Supported (specific thresholds not detailed).
• Overtemperature protection: Not explicitly specified in available data.

• Encapsulation: Epoxy resin potting (a common design for AVRs used in generator applications).
• Protection class: IP20 (dust and moisture resistant) (derived from parameters of similar AVR models).
• Operating temperature range: -30°C to +70°C (derived from industry standards for generator components).
