Automatic Voltage Regulators

Genaust AVR380 Automatic Voltage Regulator - G/A AVR 380     

The AVR 380 is a solid state device designed to give accurate and stable voltage regulation of 50 or 60 Hz AC alternators under varying load conditions. Directly replaces the Dunlite UVR100 but will also electronically replace almost all known voltage regulators with or without separate excitation.  We do have exchange units available & also offer a repair service.         RRP $653, Trade Price is less.

The AVR has several features:

*Voltage adjustment                                     *Overload sensing & shutdown
*Underspeed adjust (& voltage droop)              *Remote voltage adjustment
*T/former isolated voltage sensing                   *Wide range of stability
*Overvoltage crow bar protection

This unit will replace the following AVR's: Caterpillar, Dunlite, Stamford, Markon Contrology, Stone, McColl, Brush, Modra, Arrow, Kato, Artemus, Taiyo, Lister, Newton Derby, Reliance, Marathon, Kubota, Basler and many more.

Dunlite P1000 F88 Automatic Voltage Regulator - DUN P1000     

This Automatic Voltage Regulator is no longer manufactured.
We no longer offer a repair service or exchange units.

Dunlite produced a portable 1000VA generator that utilised this AVR, but it is now obsolete.  There is no direct replacement for this regulator, however utilising the existing plastic housing,  it is possible to externally mount and connect a Genaust PR1 or PR2, to perpetuate the alternator's operation.

Refer to "Genaust" section for details.
