Technical Specifications of the AVR

  • Range of stabilization: +/- 20%
  • Output range: less than +/- 1%, which means greater accuracy than 99%.
  • Stabilization coefficient : 20 (Ratio between the input and the output stabilization range)
  • Response time: 1 cycle
  • Frequency accepted: 50 or 60Hz + / -5% (other on request)
  • Harmonic Distortion: Do not introduce
  • Yield: 98%
  • Power Factor: 0.98
  • Sensing: TRUE-RMS independent of frequency and temperature variation
  • Adjustment system: indirect induction through a "buck-booster" transformer
  • Signaling events: display and sound messages.
  • Protection of under-voltage, over-voltage, over-load and current and phase failure
  • Thermomagnetic circuit-breaker protection on input
  • Electromagnetic contactor to drive the load and for protection even when in By-Pass mode
  • By-Pass automatic and independent for each phase uninterrupted power with programmable limits and keeping active protection of the charge.
  • Manual By-Pass independently for each phase and total to all phases
  • Control panel with display of more than 50 parameters
  • Viewing messages and events
  • Liquid crystal display with 4 lines where you can find a Voltmeter, an Ammeter, the Frequency of all three phases, the messages of events and all the data from the device.
  • Soft start: starts and after subtracting the voltage will rise slowly to the rated voltage.
  • Automatic reset and programmable delay and number of times
  • Manual reset via pushbutton or keyboard.
  • Transformer with electrostatic shield (optional)
  • Alpha-numeric keypad with 16 keys, each key lets you select for viewing 04 simultaneous parameters, also serves to set the desired variable parameter
