An automatic voltage regulator (AVR) is a device used in generators with the purpose of automatically regulating voltage.

We offer AVR parts with OEM quality and widen usage. We offer replacement 
AVR parts used for Honda, Leroy Somer, Generator Gensets and so on.

Application:Marathon and stamford alternator,FG Wilson genset with Perkins engine,Leroy Somer Generator,Caterpillar CAT engine,Kutai,Denyo 45ESI 150SPM 150ESK Genset Generator......

What are the signs of a faulty AVR in a generator?
1 - Unstable generator engine speed.
2 - Current overload.
3 - Power surge.
4 - Short circuit.
5 - Age.

What causes an AVR to fail?
It was concluded that the cause of AVR damage was due to the generator driving motor which experienced a decrease in performance so that when subjected to electric load the engine rotation experienced instability which caused voltage fluctuations where this caused the AVR to work abnormally resulting in AVR damage.

    R120 AEM230RE005 

    Description: 
    Automatic Voltage Regulator AVR 

    Specification:
    Sensing input:
    - Voltage: 277 VAC ± 10% for 1-phase,
    415 VAC line-to-line ± 10% for 3-phase,
    2-line sensing. The AVR senses the true
    average of the line-to-line waveform. Use
    the resistor (SMD) network for trouble-free
    Sensing and control of sensed voltage/regulation.
    Input power:
    - Voltage: 277 VAC rms ± 10%
    - Frequency: 50/60 Hz
    Output power:
    -Voltage: 95 VDC for 240 VAC Input
    -Current:
    4 A DC
    6 A for 30 sec. (when allowed by the field resistance)
    Operating temperature: -20ºC to +70ºC
    Storage temperature: -40ºC to +80ºC
    Voltage setting: min ± 10% of rated voltage.
    Stability setting: can be adjusted to obtain
    a correct transient response in a steady state.
    Under frequency roll-off setting: available
    Below 46 Hz for 50 Hz and below 56 Hz for 60 Hz.
    Voltage build-up: 2 Volts (L-N)
    Voltage regulation: ± 1% at the AVR
    terminals with a THC <5%.
    Thermal drift: ± 1% for 30ºC change in temperature.
    Response time: less than 50 ms.
    Closed loop response: typically 0.5 sec to recover 98% of the defined voltage for a field forcing ratio of 1:2.
    Sensing loss protection: the voltage
    should disappear when the sensing circuit is open.
    Overexcitation protection: 10 VDC to 85 VDC.
    Set point: 60 VDC
    Protection fuse: 4 A, 240 VAC.
    Potentiometer sealing: except for the
    V-trim potentiometer, all potentiometers are sealed.
    Frequency roll-off indicator: LED provided (UF).
    Sensing loss indicator: LED provided (SL).
    Overexcitation indicator: LED provided (OE).
    Protection on the devices: suitable R-C
    snubber to be provided for the device used
    to protect against voltage surges.
    Potting/Encapsulation details: the
    components on the AVR should be
    completely encapsulated with suitable PU
    resin compound to absorb transients/
    vibrations during operation.
    Alternator excitation details: (typical)
    -Full load:
    Excitation voltage: 40 to 50 V
    Excitation current: 2.5 to 4.0 A
