Generator AVR Automatic Voltage Regulator AVR AN-5-201A

• Three-phase AC input (main winding 400 VAC nominal; auxiliary winding 55–200 VAC).
• Supports self-excitation start-up (residual voltage ≥ 5 VAC/30Hz triggers 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 with generator speed/load).

• Steady-state voltage regulation: ≤ ±0.5% RMS.
• Dynamic response: Recovery time ≤ 400 ms (when voltage drops to 90% of rated value).

• Built-in over-excitation protection, under-voltage/over-voltage protection.

• Epoxy resin potting, protection class IP20 (dust and moisture resistant).
• Operating temperature range: -30℃ to +70℃.
