Description:

-Generator regulator AVR circuit diagram AVR DSR is a half-wave phase controlled thyristor type automatic voltage regulator and forms part of the excitation system for a brushless generator. In addition to regulating the generator voltage, the AVR circuitry includes under speed and sensing loss protection to ensure safe, reliable control of the generator.
-Positive voltage build up from residual levels is ensured by the use of proficient semiconductors in the power circuitry of the AVR. Which is linked with the main stator windings and the exciter field windings to offer closed loop control of the output voltage with load regulations of +/-1.5%.

Features:
• Full digital controlled regulator, based on DSP
• On-board machine installation
• Suitable for all self-regulated alternators
• Voltage supply: 40V AC-270V AC (from auxiliary winding, output voltage or PMG)
• Frequency range: 12Hz-72Hz
• “Sensing” of voltage with true RMS or average measurement (70-280V AC)
• Maximum continuous output current: 4A DC;
• Precision of voltage regulation: ± 1% from no-load to nominal load in static condition, with any power factor and for frequency variations ranging from -5% to +20% of the nominal value.
• Transient power drops and overvoltage within ± 15%
• Voltage recovery time within ± 3% of the value set, in less than 300msec.
• Transient overvoltage during start up: less than 5% of nominal voltage.
• Single phase sensing
• Parameters: VOLT, STAB, AMP and Hz can be set with trimmers (default) 50/60Hz through a
  “jumper” (default); all parameters can be programmed via software.
• Analogical remote control of output voltage is possible through external voltage (0-2.5V DC) or with a 10Kohm linear potentiometer.
• Environmental temperature: -25℃~+70℃
• Underspeed protection with adjustable threshold and slope
• Overvoltage and undervoltage alarms
• Excitation overcurrent protection with delayed intervention
• Management of temporary short circuits (start up of asynchronous motors)
• Open collector output (not insulated) signalling intervention of protective devices (insulation on optional DI1 module) with programmable activation with respect to the individual alarms and the possibility to delay intervention.
• Abnormal operation conditions storage (type of alarm, number of events, duration of the last event, total time)
• Memorization of the regulator operation time (starting from revision 11 of the Firmware)
• RS232 and RS485 serial communications interface (with optional DI1 module)
