ADVR-083

ADVR-083

Product catalog summary
Overview: The ADVR-083 is a hybrid analog/digital automatic voltage regulator (AVR) designed for brushless generators. It supports both single-phase and three-phase sensing and power input, with a capacity of 8 Amps.
Features:
  • Supports single-phase or three-phase voltage sensing and power input.
  • Includes digital voltage sensing and under frequency protection circuits to enhance thermal drift characteristics.
  • Features over-excitation protection, under-frequency protection, and soft start voltage ramping.
  • Compatible with generators operating in parallel.
  • Equipped with a high-capacity protection fuse and EMI suppression.
  • Can be used with KUTAI Auxiliary Excitation Booster to enhance motor starting capability.
Specifications:
  • Sensing Input: Voltage range of 90 to 520 Vac for 1 phase/3 phase, frequency of 50/60 Hz.
  • Power Input: Voltage range of 60 to 300 Vac for 1 phase/3 phase, frequency of 40 to 500 Hz.
  • Excitation Output: Continuous 63 Vdc 8A, maximum 90 Vdc 10A for 10 seconds.
  • Voltage Regulation: Less than +/-0.5% with 4% engine governing.
  • System Response: Less than 20 milliseconds.
  • Under Frequency Protection: Factory presets at 45 Hz for 50 Hz systems and 55 Hz for 60 Hz systems.
  • Over Excitation Protection: Adjustable from 25 to 105% of input power.
  • Thermal Drift: Voltage drift less than 3% from -40 to +70 °C, under-frequency knee point drift less than +/-0.1 Hz.
Environmental and Physical Specifications:
  • Operating Temperature: -40 to +60 °C.
  • Storage Temperature: -40 to +85 °C.
  • Relative Humidity: Maximum 95%.
  • Vibration: 5.5 Gs at 60 Hz.
  • Dimensions: 150.0 x 135.0 x 61.0 mm (5.91 x 5.31 x 2.40 inches).
  • Weight: 750 g +/-2% (1.654 lb +/-2%).
Accessories: Includes M5L35 screws and jumper terminals.
