• OverviewAVR Automatic Exciter Regulator R150The automated voltage regulator is a compact, excessive functionality encapsulatedunit The avr contains latest expertise and effective semiconductor to achieve a high degree of miniaturization when utilized to 3Ø and 1Ø ac brush-less generator inside its input and output limits, the unit provides splendid reliability The avr supplies dc excitation to the exciter feld of a brushless generator to keep the terminal voltage within shut limits from no-load to complete load The recovery time on unexpected loading is likely to be round 0 sec To get well 98% of the rated voltage Please observe that the transient performance like voltage dip and restoration time are chiefly decided by means of the generator and exciter design parameters Best functionality from the regulator could be received through retaining full load excitation around 60 Vdc InputVoltage: 240 Vac to 10% for 1 phase, 380 V up to 480 Vac to 10% for 3 phase, 2 line sensing avr senses true average of the line to line waveform Use resistor (SMD) network for hassle loose sensing & management of sensed voltage I legislation Power Voltage: 415 V for 3 section and 240 V for 1 part Frequency: 50/60HzOutput Power Voltage: one hundred and five Vdc at 240 Vac Input Current: 6 Amps dc continual 8 amps for 30 sec (when allowed by way of feld resistance)Operating Temperature: -20% to +70℃ Storage Temperature: -40% to +80℃ Voltage Adjustment: Mint 10% of rated voltage Stability Adjustment: Adjustable to get Steady state Stability good temporary reaction Remote Voltage Adjustment: To get to 10% of set terminal voltage (with 212, 1 watt pot) Droop for Parallel Operation: 4% droop for 5 amps from «U» phase Auxiliary InputA1 & A2: To 4 dc will give replace in terminal voltage through 10% Under Frequency Roll-off Adjustment: Available under forty six Hz for 50Hz &below 56Hz for 60Hz Voltage Build Up: 2 2 Volts (L-N) Voltage Regulation: To 0% at avr terminals Thermal Drift: To 1% for 300 C change in temperature Response Time: Less than 50 milli seconds Closed Loop Response: Typically 0 sec to recover to 98% of the set voltage for a feld forcing ratio of 1:2 Sense Loss Protection: Voltage should collapse, when the sensing circuit is openOver Excitation Protection: 10V dc to 85V dc Set point: 60V dc Fuse for Protection: 6 Amps, 240 Volts ac All Potentiometers: Multi-turn except hunch pot (droop-single turn) Sealing of Potentiometers: Except V-trim pot all pots are sealed Frequency Roll Off Indicator: LED supplied (UF) Sense Loss Indicator: LED offered (SL) Over Excitation Indicator: LED offered (OE) Protection On The Devices: Suitable R-C snubber to be supplied for the system used to protect this from surge Potting/Encapsulation Details: The substances on the avr must be completely encapsulated with appropriate pu resin compound to soak up transients vibrations whereas in operation Excitation Details of Alternator: (Typical) Full load Excitation Voltage: 40 to 50 Volts, Excitation Current: 2 to five Amps Terminal Marking: Refer Drawing AVR: Testing: Burn in test, thermal cycling, static test, voltage variation check, building up test, fro check, stability check, qdc check, remote voltage check, dc enter voltage checkDimension: Overall: a hundred and fifty five x one hundred ten x 50(in mm) Mounting: one hundred fifteen x 90 (in mm) Mounting Hole Dia: 9 (in mm)31) Weight: 0 KGS
