AVR R150 Automatic Voltage Regulator Replace for Diesel Generator Alternator Genset
The main function is to stabilize and regulate the voltage of the generator.

Details

1) Sensing input

– Voltage: 240 V AC ±10% for 1 phase, 380 V up to 480 V AC ±10% for 3 phase, 2 line sensing AVR Senses true average of the line to line waveform. Use Resistor (SMD) network for trouble free sensing & control of sensed voltage / regulation.

2) Input power

– Voltage: 415V for 3 phase and 240V for 1 phase

– Frequency: 50/60 Hz

3) Output power

– Voltage: 105 V DC at 240V AC Input

– Current:

6 Amps DC Continuous

8 Amps for 30sec. (when allowed by field resistance)

4) Operating temperature: -20ºC to +70ºC

5) Storage temperature: -40ºC to +80ºC

6) Voltage adjustment: min ± 10% of rated voltage.

7) Stability adjustment: adjustable to get Steady state Stability good transient response.

8) Remote Voltage adjustment: to get ±10% of set terminal voltage (with 2W / 2.5W , 1 Watt pot).

9) Droop for parallel operation: 4% droop for 5 Amps from «U» phase.

10) Auxiliary input A1 & A2: ±4.5V DC will give change in terminal voltage by ±10%.

11) Under frequency roll – off adjustment: available below 46 Hz for 50 Hz & below 56 Hz for 60 Hz.

12) Voltage Build up: ≥ 2 Volts (L-N)

13) Voltage regulation: ± 0.8% at AVR terminals.

14) Thermal drift: ± 1% for 30º C change in temperature.

15) Response time: less than 50 milli seconds.

16) Closed loop response: typically 0.5sec to recover to 98% of the set voltage for a field forcing ratio of 1:2.

17) Sense Loss protection: voltage should collapse, when the sensing circuit is open.

18) Over excitation protection: 10V DC to 85V DC. Set point : 60 V DC

19) Fuse for protection: 6 Amps, 240 Volts AC.

20) All potentiometers: multi-turn except Droop pot (Droop-single turn)

21) Sealing of Potentiometers: except V – trim pot all pots are sealed.
