Generator AVR Automatic Voltage Regulator AVR AS420

  1. Input
    • Three-phase AC input, voltage range: 170–520 VAC.
    • Supports self-excitation start-up (residual voltage ≥ 5 VAC/30Hz triggers start-up).
    • Compatible with 50Hz/60Hz systems (switchable via configuration).
  2. Output
    • DC excitation output: Continuous current up to 3 A; instantaneous peak current 6 A (≤ 10 seconds).
    • Output voltage range: 60–130 VDC (dynamically adjusts with generator speed/load).
  3. Regulation
    • Steady-state voltage regulation: ≤ ±0.5% RMS.
    • Dynamic response: Recovery time ≤ 300 ms (when voltage drops to 90% of rated value).
  4. Protection
    • Built-in over-excitation protection, short-circuit current limitation, and under-voltage/over-voltage protection.
  5. Environment
    • Epoxy resin potting, protection class IP20 (dust and moisture resistant).
    • Operating temperature range: -40℃ to +60℃.
