We have ENGGA WT-3 AVR in our regular stock!

The Brands mentioned here are for reference purpose only, our parts can exactly replace the original ones. 

The Engga AVR WT-3 is an encapsulated unit contained in a plastic case. The WT-3 Engga AVR controls the dc exciter field power of conventionla 50 or 60 Hz brushless generators that have a max 63Vdc exciter field to regulate the generator output voltage. Regulation is provided by sensing the generator output voltage, Converting it to a dc signal and comparing the signal to a reference voltage signal. An error signal is develped and used to control the dc dield power in order to maintain a constant generator output.
