Choose AVR at WDPART
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.

    Application:
    The voltage regulator type “MARK V”, is suitable for Synchronous Generators of MARELLI MOTORI make, MJB series, size range 160-225 frames. The regulator is fully insulated in order to maintain high reliability also with severe ambient conditions (high level of humidity, dust, salt atmosphere), and in case of high vibrations level. The regulator is proper both for single and 3-phase generators.
