AVR DIRCI04 | CÔNG TY TNHH ĐIỆN CÔNG NGHIỆP SÀI GÒN

• Completely digitally controlled regulator, based on DSP

• Installation on board the machine

• Suitable for all self-regulating alternators

• Supply voltage: 30Vac ÷ 280Vac (from auxiliary winding, output voltage or PMG)

• Frequency operation interval: 12Hz ÷ 72Hz

• “Sensing” of the voltage with measurement of the true effective value or the average value (0-900Vac)

• Maximum direct current at output: 5Adc; up to 15Adc during transients

• Precision of the voltage regulation: +  0.25% from no load to nominal load in static conditions with any power factor and for frequency variations included between -5% and +20% of the nominal value.

• Transient voltage droop and overvoltage within +  15%

• Voltage reset time: +  3% of the value set in less than 300 msec.

• Transient overvoltage at starting: less than 5% of the nominal voltage

• Single phase or three phase “sensing”, also on the phase with load

• Regulation at minimum, maximum or average voltage of the three phase voltages

• Parameters: VOLT, STAB, AMP, Hz, settable with trimmers (default), 50/60Hz with “jumper” (default); all the values can also be programmed via software

• Possibility of analogic remote control of the output voltage by way of external voltage (-5Vdc ÷ +5VDC) or with potentiometer

• Visualisation of the parameters and the operating conditions from a 7-segment display

• RS232 and RS485 serial communication interfaces

• Ambient temperature: -25°C - +70°C

• Under frequency protection with adjustable threshold and slope

• Overvoltage and undervoltage alarms with adjustable limits

• Excitation over-current protection with delayed intervention

• Transient short circuit handling (starting asynchronous motors)

• Signalling of winding overheating (optional module)

• Fault finder on the rotating diode bridge (currently R.B.D.)

• Protection against reference loss

• Insulated protection intervention signalling output

• Saving of the irregular operation conditions (type of alarm, number of events, duration of last event, sum of the times)

•  Possibility of working with P.F.R. function (Power Factor Regulator, currently PFR96/A)
